Differences Among Organisms
Do Species Change over Time?
Evidence of Evolution: The Fossil Record
Case Study: Evolution of the Whale
Comparing Skeletal Structures and embryonic Structures
a characteristic that helps an organism survive and reproduce in it's environment.
a group of organisms that can mate with another to produce fertile offspring. For example, all red-eyed tree frogs are members of the same species and can mate with one another to produce more red-eyed tree frogs.
the process by which populations accumulate inherited changes over time.
the solidified remains or imprints of once living organisms.
Fossil Record -
supplies evidence about the order in which evolutionary changes have occurred.
Vestigal Structures -
remnants of once useful structures in organisms. Whales have the remnants of hind-limb bones inside their bodies even though they have no use for them now.
Change Over Time
All living things share the same kind of genetic material suggesting a common ancestor. Organisms more closely related have more similarities in their DNA. Chimpanzees and Gorillas have very similar DNA. Chimps and Toucans do not.
