• The modern concept of
biological evolution began in
the nineteenth century thanks
to the ideas of Lamarck and
creationists of the time (
Darwin).
• Lamark
• Darwin
THE THEORY OF EVOLUTION
OF LAMARCK • Lamarck proposed
that the evolution of species is a progression, in which the organisms causing life forms are increasingly complex and "perfect". His theory was based on the following principles:
1-All organisms tend to perfection, because of an internal force or life force.
2-Changes in the environment generate among agencies needs .
3-The needs make organisms are forced to use certain organs, which are developed for their
use. By contrast, the disuse of an organ or structure causes atrophy.
4-Faced with the changing environment, there are features in organisms called acquired characteristics. They are inherited from generation to Lamarck. The great contribution is to have postulated the first scientific theory of evolution.
THE THEORY OF EVOLUTION
OF DARWIN • Life forms are not
static but evolve, species change continuously, some others originate and become extinct.
The process of evolution is gradual, slow and continuous, discontinuous jumps or sudden changes.
Similar organisms are related and descended from a common ancestor. All living organisms can be traced to a single origin of life.
Natural selection is the key, in two phases, which explains the whole system.
The first stage is the
production of variability: generating spontaneous changes in individuals. The second, the selection through survival in the struggle for life: the fittest individuals, those born with favorable spontaneous changes to address the environment will be more likely to survive, reproduce and leave offspring with these advantages.
Mammals are a kind
of vertebrates
characterized
especially because
mothers feed their
babies through the
breasts. That gives
them the name.
The mammals
descended from
reptiles. Not
appear to be very
similar now,
because mammals
appeared about
195 million ago
years. Back then,
reptiles ruled the
world.
The mammals are the
animals most
complex and
evolved. They can
live in land, fly, or
live in water.
CHARACTERISTICS OF
THE MAMMALS • Of general form we
can say that the
mammals are
characterized by
the following thing:
• They are of warm
blood and his
temperature is
constant.
• Most of the
mothers are
provided with
mammary glands.
• The mouth is
surrounded with
lips in order that
this way the
babies can suck.
• They present
abundant glands
and, generally,
abundant hair.
• The majority have
teeth.
• They have
pulmonary
breathing.
• The circulation is
double
(pulmonary and
general).
• The majority of
they are
viviparous.
The proboscis
monkey:
• Both males and
females have a big
nose. His nose
swells and turns
red when they are
excited or angry.
They also create
loud noises as a
warning when they
sense danger
• Ninety-five percent
of their diet
consists of leaves
of mangrove trees.
But they also eat
fruits and seeds.
• The females give
birth the one baby.
In general, they
give birth in the
night. Males reach
sexual maturity at
4-5 years and
females at 4 years.
Their life
expectancy is
about 20 years.
• It is in danger of
extinction, they are
found only on the
island of Borneo.
The naked mole rat:
• This animal is a
subterranean rodent
that lives in complex
tunnel systems
isolated from the
outside world, with
individuals who live
in colonies in which
only a few are
breeding females.
• They have the size
of a mouse, which
lives in arid
equatorial East
Africa.
• A naked mole rat,
can live at least
getting to reach the
thirties. Moreover it
is an animal
resistant to cancer,
some types of pain
and can live without
oxygen a long time
so hold the record of
holding without
breathing between
mammals.
• Interested in their
incredible abilities,
researchers around
the world have
investigated very
thoroughly his life
underground.
• The almiqui is
known by the
common name or
solenodontes
almiquís in Cuba.
They are
insectivores own
the Antilles and
are among the
rarest mammals in
the world. There
are two very
similar species:
the almiqui of
Cuba (Solenodon
cubanus) and
paradoxical
almiqui
(Solenodon
paradoxus), who
lives on the island
of La Spanish
(Dominican
Republic and
Haiti).This animal
is a true living
fossil whose
ancestors of bones
found dating back
30 million years.
This is a primitive
mammal, and of
the few who own
venom.
• The body has
a length of 28
to 32 cm and
the tail is from
17 to 27 cm.
From
nocturnal
habits, walks
in zigzag their
saliva is
poisonous:
the second
incisor on
each side of
its lower jaw
has a slot
connected
with a poison
gland, the
poison is very
active: when
two of these
animals are
and fight
happens that
one of the two
dies poisoned
because of
the opponent
bites.
Mammal that put eggs
• The platypus is a
semi-aquatic
mammal species
endemic to eastern
Australia and
Tasmania.
• The bizarre
appearance of this
egg-laying mammal,
poisonous, with
beak-shaped snout
duck, beaver tail
and otter paws
baffled European
naturalists when
they first
encountered it.
• It is one of the few
venomous
mammals, males
have a spur on the
hind legs that
delivers a venom
capable of
producing severe
pain to humans.
• The platypus is the
animal emblem of
the state of New
South Wales.
• The grizzly bear
is a subspecies of
the brown bear's
largest planet,
which usually lives
in the highlands of
U.S. territory. They
can reach weights
up to 550 kg,
although some
specimens have
reached weigh 680
kg. They measure
1 meter to 4 feet,
while standing,
reaching 2.4
meters.
• The muscles of the
hind legs are
strong enough for
the bear to rely
solely on them,
and to allow them
to walk short
distances in
bipedal form. Can
reach 55 miles per
hour when running
on 4 legs.
• They are
omnivores and
before entering
hibernate usually
increase about
180 kg.
A grizzly bear killed a
trekker in Yellowstone
National Park
• A hiker who was
visiting
Yellowstone
National Park died
after attack by a
grizzly bear in
2011.
• The incident
occurred 2.5
kilometers from
the start of the
Wapiti Lake when
a couple of tourists
came across a
bear and her cubs.
• According to park
officials, the
animal reacted
violently to
humans to
perceive who were
a threat.
• The man died after
the bear attack
without him time to
transfer him to a
hospital, while the
woman was
unharmed.
• The last time a
person was killed
by a grizzly bear
attack in
Yellowstone was
in October 1986.
• The blue whale is
the largest creature,
with a 170-ton,
nearly 35 meters
long, the weight of
22 elephants and
giraffes lying over 7.
• They feed almost
exclusively krill but
also small amounts
of copepods. The
species of
zooplankton eaten
by blue whales
varies from ocean to
ocean. An adult can
eat up to 40 million
krill in a day and can
consume during
high season power
up to 4 tones of krill
in one day.
• The male sexual
maturity occurs at
about five years of
age, when
measured around
20 to 21 m and from
females when
measured 21-23 m,
also at five years.
The history of Koko • Koko (born July 4,
1971 in San
Francisco,
California) is the
name of a gorilla
trained by Dr.
Francine 'Penny'
Patterson. The
objective of the
training was to
communicate with
her through more
than 1,000 signs
based on sign
language. It
comprises about
2,000 words of
spoken English.
• Koko has lived
most of her life in
Woodside,
California.
• It is also
recognized
worldwide as one
of the few animals
able to show their
feelings clearly.
• Koko feels a great
affection for cats.
In studies it has
been relating from
his childhood with
them.
• The shrews have a light weight of just 2 grams and a head body length, not including their tail, of only 3-5 cm. They are characterized by small eyes and a long snout with whiskers very sensitive. They are similar to a mouse, but are related to the moles.
• They are mammals that are most active. They hunt their food both day and night. Many species,
especially the Europeans eat their own weight in insects daily, and can die if they spend more than four hours without eating. Their food is based on invertebrates, and sometimes can take carrion.
• Are defended from predators by scent glands that produce an unpleasant odor that makes them unattractive dish for animals with a good nose.
Black rhino:
• It differs from the
white rhino in color
and smaller size
(although,
however, reaches
1.6 meters tall and
weighing 1,500
kilos) it feeds on
the leaves of
shrubs and low
trees to a lesser
extent, while the
white rhino eating
grass on the
ground and has a
lip straight and
wide.
• The black rhino
charge when beset
caused a sensation
when in the
nineteenth and
twentieth centuries,
European
explorers and
trappers
penetrated into
Africa and began
killing rhinos
hundreds.
• The giant panda is a kind of
mammal order of
carnivores.
• The main food is
bamboo panda
(around 99% of
their diet), but also
feeds on fruits,
small mammals,
fish, and insectos.3
is a good climber,
but is rarely seen in
the trees. Fits
captivity and
thanks to their hair
easily withstands
winter conditions of
their habitat.
• Is in danger of
extinction as the
species is highly
localized. In 1600
living in the jungles
and 188 in
captivity, reports
show that the
number of pandas
living in the wild is
on the rise.
• Unfortunately is in
danger of
extinction due to
hunting and habitat
destruction
• The sheep Dolly
born July 5, 1996,
was the first
mammal cloned from
an adult cell. Its
creators were
Scottish scientists
Ian Wilmut and Keith
Campbell.
• The cell from which
Dolly was coming
from a particular
tissue, the mammary
gland of an adult
animal (a sheep End
Dorset six years).
• Dolly lived always at
the Roslin Institute.
There was crossed
with a male Welsh
Mountain to produce
six offspring in total.
• The February 14,
2003, Dolly was
euthanized due to
progressive lung
disease. Necropsy
showed that it had a
form of Jaagsiekte
call lung cancer, a
disease of sheep
only.
• Birds are
vertebrates,
warm-blooded.
• They have two
hind limbs (two
legs) and two
front limbs (two
wings).
• Serve wings to
fly but not all
birds fly.

most
numerous
vertebrate
species. With
over 4,000
species.
• The largest bird
was Argentavis

that he lived six
million years in the
territories that
today form
Argentina.

meter wingspan
and could weigh
up to 100 kilos.
Flight soared
jumping from a
high place.
He could reach
speeds up to 108
km / h in the right
conditions.
• Cassowaries are solitary birds, unable to fly. They live in the rainforests of Australia and New Guinea. It is the second heaviest bird in the world after the ostrich.
May infringe fatal injuries to an adult human, with their solid hitting and strong legs, opening the body of the intruder with its sharp claws.
The inside toes have long, sharp claws
like knives, which are a deadly defensive weapon.
They can measure about 2 meters and weigh 70 kilograms. If you want to escape them think that reach up to 50 km / h through the dense forests. They can jump up to 1.5 m and are also good swimmers.
• The world's smallest bird is the Bee Hummingbird (Mellisuga helenae) also known as bird fly or bee elf.
• Is 6 inches from beak to tail, and weighs on average about 1.8 grams. The male is still smaller than the female and has a head and neck bright red, metallic blue back and wings, white gray chest and abdomen. In flight flaps its wings about 80 times per second, and
up to 200 times per second during mating.
• Heart rate has the second fastest of all animals, and is the bird with the least amount of feathers.

considerable size,
reaching up to 81
inches in size. It has
broad and rounded
wings, long tail and
prominent pointed

nests in those tall
trees of the vast
forests where it lives.
• Recent reports place
it in Sarapiqui and
Osa.
• An individual
held captive
at the Zoo La
Marina in San
Carlos. He
was caught
near the
border with
Nicaragua.
• It feeds on
snakes, frogs,
hammers,
and
occasionally
birds.
• The main
cause of
extinction is
habitat loss
due to
deforestation.
• The lone Aquila

reach up to 76
inches in size and 3
kilos of weight. Their
name comes from
their customs and to
be quite scarce.
• The body is covered
with dark gray
plumage, of the

prominent crest.
The tail tips are
white. Their wings
are wide and its tail
is short. Young
individuals are
different. They are

black.
• It lives in dense
forests, often fly at
high altitudes. It
extends from
northern Mexico to
northern Argentina.

such as monkeys
and other arboreal
mammals and birds,
reptiles and insects.
• The sun heron is a
rare bird, with a size

short. It feeds on
small frogs, crabs,
shrimp and insect
larvae river that
starts from the
stones.
• The cause of his
disappearance is
forest destruction
and pollution of
streams and rivers,
affecting habitat and
food sources.
THE DANGER OF BEGIN HIT
DRIVES EVOLUTION OF A TYPE
OF SWALLOWS
• In the U.S., it is estimated that more than 60 million birds die each year trampled. So intense is the pressure, that 100 years of the automobile has been enough for some animals develop in order to prevent abuse. E Neither the helmet or seat belt: the idea is to run. Or rather, maneuver better.
• The process has been surprisingly rapid. None of isolated islands for thousands of years that alerted Darwin. In 30 years of study has been able to measure the results, published by Charles
Brown of the University of Tulsa (Oklahoma) and Mary Bomberger Brown, University of Nebraska-Lincoln, in the journal Current Biology. The couple has measured the number of bird nests trampled and size. And the relationship is clear: children grow more and die less.
• The researchers
claim that since
1982 have
traveled the
same roads in
the same area
every drink stop
to pick up that hit.
To put it in
context,
measures the
bird deaths by
natural causes,
estimated the
total population
and other factors
such as the
presence of
predators or
traffic volume.
The result is that
there has been a
steady decline in
the size of the
birds.
And those who died
in an accident
had longer wings
than average.
The Reptiles are
a group of
vertebrates emerged
dinosaurs age. They
have adapted to live
out of the water, but
one part of them live
in the water. Her
skin are very
resistant and scaly
thanks to keratin, a
protein. Another
adaptation of reptiles
are their lungs, have
very developed. Are
reproduced internally
and are oviparous,
put eggs.
CURIOSITY!
The reptiles can
controle her corporal
temperature.
The cobra is a
venomous snake of
the family Elapidae.
Known for their
menacing appearance
and bite. They live in
tropical and desert
areas of southern Asia
and Africa.
It is easy to recognize
because they display a
kind of "hood" in the
head when irritated or
in danger.
They feed on rodents
and birds, which kill by
injecting a neurotoxin
through fangs. Their
predators are
mongoose and some
birds.
• The saltwater
crocodile (Crocodylus
porosus) is a kind of
family crocodilio

the largest crocodile
in the world and the
largest reptile on the
planet. they live in
swampy areas From
South Asia to the
north of Australia.
• Males weigh
between 900 and
1500 kg, and
measuring between
6 and 7 meters long.
Females are smaller
than males,
between 2 and 3
meters in length and
weighing 500 kg.
• They feed mainly on
land of the buffalo
and their predators
when they are small
tigers.
In the breeding
season, after mating
the female lays up to
90 eggs hidden
land, depending on
temperature are
born male or female.
Then the female
carries her breeding
in a cavity in your
mouth, to security in
the water.
• The most famous
reptile is the sea
turtle because
they have
appeared on many
films for kids, for
example NEMO.
Also are very
famous because
are very large, it’s
measuring
between 4 and 5
meters.
• They feed of plants
or a wide range of
animals.
• We can be find it in
the waters over
continental sheves.
• Sea turtles are
almost always
submerged, and,
therefore, have
developed
an anaerobic
system of energy
metabolic.
• The
chamaleon is
the most smallest
specie of reptiles.
• There are
approximately
160 species of
chameleons,
They are
distinguished by
theirzygodactylou
feet.
• They measuring 1
meter the largest.
• It’s weight
approximately 1
gram.
• They feed the
little insects with
her tongue, that
take fast and hunt
their prey.
• The most strangest reptile is the turtle matamata. The matamata is unmistakable. It has a brown or black carapace 45 cm long. The plastron is narrow, narrow, sharply cut forward and pulled back and the male is concave.
• The head is triangular, flattened and elongated. It has numerous bumps on the skin. It has two whiskers and two additional filaments chin. The snout is elongated
and tubiforme. The upper jaw is neither bend nor trimmed. The neck is flattened rather long, rather than the spine inside the shell, and have protrusions on both sides giving it saw aspect. Head, neck, legs and tail are gray-brown in adults. Each front leg has five webbed claws swim. The tails of males are thicker and longer.
• We can be found
in lazy rivers, calm
lakes, marshes
and swamps.
Lives in tropical
forest in eastern
Bolivia, Peru,
Ecuador and
Colombia,
southern
Venezuela and
Guianas, and
northern and
central Brazil.
• The insects are a
group of
invertebrate
arthropods,
because they have
the body and the
articulated legs.
• Is divided in:
The head: Here, they
have two antennas,
two eyes, and the
mouth, which
allows them to
crush the food.
The thorax: Divided in
three segments,
where they have
three couples of
legs and two
couples of wings
(not all have wings)
Abdomen: Is divided
in eleven
segments, where
they have the
digestive device,
the excretory and
reproductive
apparatus.
• At the breeding
season females
become very
aggressive and
sometimes can
eat the male.
• Insects eat any
food substance,
but each species
has different
habits.
The mantis, has
specialized legs
for hunting other
insects, or the
woodworm that
feeds wood just.
• Ants have five
noses.
• The sexual organ
of a spider male is

in volume and
weight.
• They can measure
10 cm and are
native to tropical
Africa, they live feed
on the sap and fruit
trees and feed on
nectar and pollen,
and fruit and sap.
• Like most beetles,
have a pair of wings
strengthened like
protective covers
that act as their
secondary pair of
wings and
abdomen. Each
beetle legs ends in
a pair of sharp
claws that provide
great grip when
climbing.
• The males have a
Y-shaped horn on
the head that is
used in battles
against other males.
• Apart from its
enormous size, the
beetles are
surprisingly strong.
• Small wasps of
gender
Trichogramma are
considered the
world's smallest
insects. Without
actually just a
millimeter in length
are known for
many farmers who
used to control
pests in their crops.
They can be seen
on other insects to
those used to travel
long distances.
• These small wasps
are currently used
in the control of at
least 28 species of
insects. The female
wasps lay their
eggs inside the
eggs of other
insects and their
larvae consume
the embryo and
other parasitized
egg contents.
• The mosquito kills millions of
people each year.
Contagious yellow
fever, dengue
fever, encephalitis,
West Nile virus
and malaria from
one person to
another, without
being affected by
these diseases.
• Females have a
mouth parts that
form a long
proboscis ready for
piercing the skin of
mammals and
suck its blood. This
way inject eggs
and also pass
diseases.
• The males diet
consists of nectar,
sap and fruit
juices, usually high
in sugar. The
females have.
• Bird wing
butterflies is a
kind of
lepidopteran family
ditrisio
Papilioninae.
Butterfly is the
world's largest
daytime. Lives in
New Guinea.
• The females are
bigger than males
with markedly
shaped wings
wider round. The

butterfly is a kind
of Lepidoptera
Nymphalidae
family ditrisio.
Native to the
deserts of
Venezuela.
• Females have a
large reduction of
the wings and
deformation of the
rib of the same, so
it is a unique case
of braquiptería
butterflies. Its
natural habitat is
restricted to wet
moors.
• It is considered in
danger of
extinction by its
restricted
distribution within
180km2, habitat
vulnerability to
climate change and
the pressure of the
fire and livestock,
even within
protected areas.
The butterflies are losing
ground in Mexico • Monarch butterflies
that come to
Mexico every
November to
hibernate are so
numerous that
there is no way of
telling. Millions,
tens of millions or
hundreds of
millions.
• The only way we
have to measure
the population is to
calculate the area
occupied by
forests.
• This season the
area has declined
by 59%: 1.9
hectares compared
to 2.89 in 2011-
2012 hibernation
cycle, which is the
lowest level in 20
years, since no
data.
• They travel more
than 4,000 miles
south and go
through three
countries: Canada,
from whence,
United States,
which accounts for
most of the
journey, and
Mexico.
• It is during that return
trip north when
problems arise that
are affecting their
population. "The
change in land use
from agriculture to
industry in the U.S.
and the use of
agrochemicals has
led to a reduction in
the presence of
milkweed plants, the
only food of these
insects.
• Luckily there and
citizen initiatives that
address it as the
teacher at the
University of Kansas,
Chip Taylor. The
project led, Monarch
Watch, coordinates
volunteers to replant
milkweed in their
gardens or in areas
that are on the route
followed by these
insects.
• The amphibians
are a vertebrate
animal.
-Characteristics of
amphibians :
They have four
legs and have
cold blood.
At first gill
breathing is,
after lung and
skin.
They reproduce
by eggs,
normally with
external
fertilization and
metamorphosi
s grow.
Metamorphosis:
• It is the process of
physical changes
of amphibians
from the birth until
they are adults
1 - The fertilized egg
is formed by
external water. It is
surrounded by a
gelatinous mass.
2 - The egg is
transformed into
an embryo, which
moves within the
gelatinous shell.
3- Birth of the
tadpole. Has tail
for easy
movement and
breathe through
gills.
4 - When begin adult,
you leave the legs
and tail. Breathe
through lungs and
skin.
• The most
dangerous
amphibian is
FROG DARK
GOLDEN. They
are more
poisonous frogs
earth. It
measure
approximate 60
or 70 mm. It is
brightly colored (
If they are bright
colors can be
dangerous
because they
are poisonous).
• with 1g its
venom can kill
15,000 humans.
Is very
dangerous.
THE WORLD'S
LARGEST TOAD • This summer in
northern Australia,
three biologists
have found a toad
the size of a dog of
small stature.
The race was toad
Bufo marinus, and
has been called
Toadzilla.
Toadzilla weighs
about one
kilogram, and is the
largest cane toad
ever found in
northern Australia,
as reported by
three biologists.
Environmentalists
have sought to
curb the
proliferation of
these poisonous
animals in
Australia, since
they were brought
into the country
from the island of
Hawaii in the early
30s of the last
century.
• This is a frog from
New Guinea, does
not exceed 7.7
mm.
Of the more than
60,000 vertebrates
known to man, the
largest is the blue
whale, with an
average of more
than 25 meters
long.
Before the animal
was a fish smaller
than 8 millimeters
Indonesia.
It was discovered in
early 2012 by U.S.
scientists in the
jungles of Papua
New Guinea.
The diminutive size
