Some organisms that share a common ancestor have features that have different functions, but similar structures. These are known as
vestigial structures
analogous structures
homologous structures
embryology
What is this an example of?
Homologous structure
Analogous structure
Vestigial organs
Functional adaption
In convergent evolution, organisms share physical similarities that can be seen because they
have a common ancestor
live in the same type of environment
develop homologous structures
are closely related
Two species living in similar environments, but a very long distance away look very similar. However, that are not closely related (analogous). Their resemblance is most likely an example of.
sexual selection
temporal isolation
convergent evolution
divergent evolution
Analyze the answer choices below. Choose all of the answer choices that describe Convergent Evolution.
Organisms share a common ancestor
Analogous Structures support Convergent Evolution
Organisms have similar visible structures because they live in similar environments
Organisms change together in order for them to survive
Analyze the answer choices below. Choose all of the answer choices that describe Divergent Evolution.
Organisms have similar internal structures
Organisms share a common ancestor
Organisms have to live in similar types of environments
Homologous structures support Divergent Evolution
Sharks and dolphins look very much alike-- both have streamlined bodies, fins, and sharp teeth. Sharks and dolphins, however, show every few similarities in protein and DNA structures implying that they are not closely related. The body structures have evolved independently. Which term is used by evolutionary biologists to describe the process by which two separate species may evolve in a similar way and come to resemble one another, but have no relation.
