Peppered Moth Activity
• Pick a spot in the room to camouflage your moth• Color the moth to blend in to the room– 6 points for one color– 7 points for 2 colors– 8 points for 3 colors
• Put the moth in the correct spot to camouflage it.• You will receive 2 points if it is not found and 0 points
if it is found

Evolution
![Page 6: Peppered Moth Evolution Melanism. Answer on a separate sheet 1.What are the two types of peppered moths? 2.What color were most peppered moths originally?](https://reader030.fdocuments.us/reader030/viewer/2022032607/56649ebb5503460f94bc3e47/html5/thumbnails/6.jpg)
What is evolution?
• The process by which modern organisms have descended from ancient organisms
• Changes that are beneficial (adaptations) are passed on to offspring
• Goal of all living things: pass genes on to another generation– Good adaptations increase fitness– Bad adaptations – what happens?

Voyage of the Beagle
• Charles Darwin– Born in England,
1809– Boarded the Beagle
in 1831 for it’s journey around the world

The Voyage of the Beagle
![Page 10: Peppered Moth Evolution Melanism. Answer on a separate sheet 1.What are the two types of peppered moths? 2.What color were most peppered moths originally?](https://reader030.fdocuments.us/reader030/viewer/2022032607/56649ebb5503460f94bc3e47/html5/thumbnails/10.jpg)
Darwin’s Observations – Evolution by Natural Selection
• Patterns of Diversity– Darwin noticed that organisms living in different
habitats and environments had very different traits
– And…similar environments had organisms with similar traits
• Struggle for existence – species compete for resources
![Page 11: Peppered Moth Evolution Melanism. Answer on a separate sheet 1.What are the two types of peppered moths? 2.What color were most peppered moths originally?](https://reader030.fdocuments.us/reader030/viewer/2022032607/56649ebb5503460f94bc3e47/html5/thumbnails/11.jpg)
Darwin’s Observations – Evolution by Natural Selection
• Descent with modification – new species descend (come from) other species with changes (modifications)
• Survival of the fittest – the fittest organisms will live and pass their genes on to a new generation
![Page 12: Peppered Moth Evolution Melanism. Answer on a separate sheet 1.What are the two types of peppered moths? 2.What color were most peppered moths originally?](https://reader030.fdocuments.us/reader030/viewer/2022032607/56649ebb5503460f94bc3e47/html5/thumbnails/12.jpg)
Evolution by Natural Selection
• Darwin used his observations to come up with the theory of evolution by natural selection
• The environment will determine which organisms will live or die– Pass their genes on to a new generation– Determined by adaptations – traits of an organism
![Page 13: Peppered Moth Evolution Melanism. Answer on a separate sheet 1.What are the two types of peppered moths? 2.What color were most peppered moths originally?](https://reader030.fdocuments.us/reader030/viewer/2022032607/56649ebb5503460f94bc3e47/html5/thumbnails/13.jpg)
Adaptations
• Darwin looked at the finches on the Galapagos Islands– Noticed beak shape differed– Why would the beak shape be different?
![Page 14: Peppered Moth Evolution Melanism. Answer on a separate sheet 1.What are the two types of peppered moths? 2.What color were most peppered moths originally?](https://reader030.fdocuments.us/reader030/viewer/2022032607/56649ebb5503460f94bc3e47/html5/thumbnails/14.jpg)
• Darwin looked at the finches on the Galapagos Islands– Noticed beak shape differed– Why would the beak shape be different?
– Diet– Habitat– Defense mechanism
Adaptations

Evolution
• Fitness: ability of an organism to survive and reproduce viable offspring– Viable offspring are offspring that can survive and
reproduce
• Adaptation: characteristic in an organism that increases fitness

Natural Selection vs. Artificial Selection
• Natural Selection: environment chooses which traits are beneficial and will increase fitness
• Artificial selection: humans choose which traits are beneficial– Examples: breeding dogs

Evidence for Evolution
![Page 20: Peppered Moth Evolution Melanism. Answer on a separate sheet 1.What are the two types of peppered moths? 2.What color were most peppered moths originally?](https://reader030.fdocuments.us/reader030/viewer/2022032607/56649ebb5503460f94bc3e47/html5/thumbnails/20.jpg)
Evidence for Evolution
• Fossils• Geographic distribution• Homologous body structures• Vestigial organs• Similarities in embryology
![Page 21: Peppered Moth Evolution Melanism. Answer on a separate sheet 1.What are the two types of peppered moths? 2.What color were most peppered moths originally?](https://reader030.fdocuments.us/reader030/viewer/2022032607/56649ebb5503460f94bc3e47/html5/thumbnails/21.jpg)
Fossils
• Fossils: remains of ancient life• Shows progression from ancient to modern
![Page 22: Peppered Moth Evolution Melanism. Answer on a separate sheet 1.What are the two types of peppered moths? 2.What color were most peppered moths originally?](https://reader030.fdocuments.us/reader030/viewer/2022032607/56649ebb5503460f94bc3e47/html5/thumbnails/22.jpg)
Fossil Record: Determining Age
• Radioactive Dating: use element’s half-life to determine age of fossil– Half life: how long it takes for half of the element
to decay or disappear from the fossil• Relative Dating: look at which layer of rock the
fossil was found in to compare age to other fossils around it
![Page 23: Peppered Moth Evolution Melanism. Answer on a separate sheet 1.What are the two types of peppered moths? 2.What color were most peppered moths originally?](https://reader030.fdocuments.us/reader030/viewer/2022032607/56649ebb5503460f94bc3e47/html5/thumbnails/23.jpg)
Geographic Distribution
• Animals living in similar environments have similar anatomies and behaviors– Showed that evolution in similar environments
caused certain traits to be chosen as beneficial• Each animal experienced descent with
modification from common ancestors
![Page 24: Peppered Moth Evolution Melanism. Answer on a separate sheet 1.What are the two types of peppered moths? 2.What color were most peppered moths originally?](https://reader030.fdocuments.us/reader030/viewer/2022032607/56649ebb5503460f94bc3e47/html5/thumbnails/24.jpg)
Homologous Body Structures
• Structures that have different mature forms but develop from the same embryonic tissue
• Limbs of reptiles, birds, mammals (arms, wings, legs, flippers) all come from the same basic bones

Vestigial organs
• Traces of homologous organs in other species• Organs are not necessary for survival• May resemble miniature legs, tails or other
structures• Examples in humans: – Tail bone– Appendix

Similarities in Embryology
• Embryology: study of embryos, development before birth, hatching
• Development in vertebrates is extremely similar
• Common tissues and developmental patterns

Human Evolution
• Hominids – “great apes”– Human ancestors AND humans belong to this
group• Similarities in body structures, DNA, development
• Over time, organisms changed

Human Evolution
• As human ancestors moved from location to location, traits were deemed beneficial or not
• Different traits, different environments caused changes in humans and our ancestors over time
