Darwin
Who developed the theory of evolution?
Charles Darwin
What is natural selection?
Organisms with beneficial traits survive and reproduce
What is a fossil?
Remains/imprints of organisms
What are homologous structures?
Same structure, different function
What molecule is compared between species?
DNA
What voyage helped Darwin form his theory?
HMS Beagle
What is an adaptation?
Trait helping survival/reproduction
What are trace fossils?
Evidence of activity
Human arm and whale flipper are what type?
Homologous
What does similar DNA suggest?
Close relationship
What islands did Darwin study finches on?
Galapagos Islands
Give one structural adaptation.
What were the differences between the finches on the island Darwin studied?
Beak shape (For Finches)
Camouflage
Which rock layer is the oldest?
Bottom layer
Bird and butterfly wings are what type?
Analogous
What field studies embryos?
Embryology
What is variation?
Inherited differences in a species
Why did darker moths survive better?
Better camouflage
What is the difference between relative and absolute dating?
Comparison vs actual age
What are vestigial structures?
Structures no longer useful
Why are embryos evidence for evolution?
Shared developmental traits
Why are variations important?
Helpful traits increase survival
Explain how natural selection changes populations over time.
Helpful traits become more common
How do fossils support evolution?
Show organisms changed over time
Why do homologous structures support evolution?
Suggest common ancestry
How does molecular biology support evolution?
Shared genes/proteins show common ancestry
