Treat this journal with care and respect. It will be very helpful for the bundled homework package.

Your journal is your responsibility. If it becomes lost or damaged it will significantly reduce your grade.

• BLACK SLIDE: Pay attention, follow directions, complete projects as described and answer required questions neatly.

• Keep an eye out for “The-Owl” and raise your hand as soon as you see him.– He will be hiding somewhere in the slideshow

“Hoot, Hoot”“Good Luck!”

• Class Expectations– You can show respect by…

• Listening when the teacher or others are talking.– One speaker at a time, please raise your hand.

• What’s wrong with this cartoon?

• Answer! Dinosaurs and people did not coexist. They are separated by 65 million years of evolution.

Not sure if children with such large heads can pass through such a narrow pelvis.

• You can now complete this question on the bundled homework.

• Remember, dinosaurs went extinct about 65 million years ago.– Mammals emerged after the KT event / volcanic

debris / and microbes that wiped out the dinosaurs.

• Earliest primate fossil (Ida)– 47 million years old. – Early linage that may have given rise to modern

monkeys and apes.

• Power grip.

• The power grip was believed to help human break bones / scavenge animal remains with a sharp pointed rock called a hand axe.

• Vultures are a clear sign that an animal is dead. Easily seen from a distance for early Hominids on the dry African savannah.

• Precision grip

• Stone tools advanced to become more precision based.

• Stone tools advanced to become more precision based. Allowing early hominids to cut, and eventually being a part of weapons such as spears.

Which one is a picture of a human hand?

Bipedalism: Walking on two feet (regularly).Bipedalism: Walking on two feet (regularly).

• Laetoli footprints – Dated 3.6 million years ago.

• Not bipedal!

• How does a drying landscape cause a primate to become bipedal?– Africa began to dry 5-8 million years ago. The lush forest

turned into Savannah. How does this change lead to a change in hominid behavior and physiology?

• Hominids had to travel over greater and greater distances over time. Standing tall allowed hominids to see over the grasses, and traveling on two feet became easier than four. The life in the trees became a life on the ground.

• Lots of new evidence suggests that Africa went through serious environmental shifts during this period.

• Lots of new evidence suggests that Africa went through serious environmental shifts during this period.– From lush and wet, to dry, and then back again.– This shifting was believed to have accelerated evolution.

• People are not really correct when they assume people just came from monkeys.

• Humans are instead just a branch from a tree which includes thousands of primates, some still around, most have gone extinct.

• There are many connections and similarities that people share with primates.

• There are many connections and similarities that people share with primates.– Our DNA is close to 94% the same as a chimpanzee.

• Humans are closer genetically to chimps than horses are to zebras.

• You could get both a heart and blood transfusion from a chimpanzee.

“Your not getting my

heart you crazy human.”

• First hominid found in 1924 (Leakey’s) at Olduvai Gorge.

“I wonder if the teacher will use our names on

the review game?”

• Just a few of the important sites where hominids have been found.

• Australopithecus boisei – Found in 1959

“I’m not believed to be a good candidate for direct human

ancestry because I’m big.”

• Sahelanthropus tchadensis Oldest Hominid– 6-7 million years ago.

• Australopithecus afarensis– 3.0 to 3.9 million years ago.

“My teeth are more like a

human than an ape.”

• Named “Lucy”

Many species of hominids evolved and Many species of hominids evolved and have become extinct (lots of fossil have become extinct (lots of fossil evidence).evidence).

• Australopithecus

• Australopithecus– Meaning “Southern Ape”– A group split from Australopithecus to become “homo.”

• The word homo– Short for the word "human" from humanus,

We are the only surviving hominid We are the only surviving hominid (Homo sapien sapien).(Homo sapien sapien).

• Repeat, we are the last surviving hominid.

“I am just part of a marketing

campaign, I just spent four hours in

make-up.”

• Other hominids include

• Australopithecus africanus

• Homo habilis– 2.4 to 1.5 million years ago.

“Oohg, nee da

Oghh faah Beeodia.”

• Homo habilis

“I used primitive tools such

as this hand axe.”

“I was also capable of

rudimentary speech.”

“This is garbage.” “How can they tell

if something talked millions of years ago?” “I’ve

had enough!”

• The Broca's area of the skull which is in charge of speech is enlarged.

“I’m sorry I yelled earlier.” “I didn’t know about the Broca’s area.”

• Homo erectus– 1.8 million and 300,000 years ago

“I was the first hominid

to leave Africa.”

“See yah.”

• Homo ergaster– 1.7 million years.

• Homo erectus– The first appearance of hominids outside of

Africa. – The first appearance of systematic hunting. – Tool making and use of fire. – First indication of extended childhood. – Homo erectus was capable of a more

complex life.
