What does natural selection predict about mimicry camoflauge homologous structures and vestigial structures?
a
Does homologous mean that structures are similar due to having common ancestry?
homologous structures- same structure/different functions in common ancestors analogous structures-same functions/differnt structures not in common ancestors vestigial-show evolutionary history/structures that arent used anymore (i.e. human appendix/human tailbone)
Both homologous and analogous forms of these result from evolution?
Structures
What is the difference between homologous structures and analogous structures?
Homologous = same origin, different function (arms vs. wings) Analogous = same function, different origin (panda thumb)
How are homologous structures different from analogous structures?
Yes, homologous structures have common bone and muscle structures suggesting that they came from an common ancestor while analogous structures do not share any similarity in features, suggesting that they derived from two separate origins.
What evolution has produced many of the analogous structures in organisms today?
They don't. Homologous structures provide evidence for evolution not analogous structures.
How are analogous and homologous structures different?
They are different because homologous structures have the same structure, but serve a different function. Like mammal arms(human, bat and whales). Analogous structues are different structures, but serve the same function. For example, bat wings and butterfly wings.
Is a wing of a bird homologous to the wing of a cat?
In biology, homologous structures are defined as structures which serve the same purposes because they evolved from the same source (divergent evolution), the opposite of analogous structures, which serve the same purpose but evolved through convergent evolution. Birds' wings and bats' wings are both homologous and analogous. As wings, the two are analogous, but as forelimbs, the two are homologous.
What Organs that are so reduced in size that they are just vestiges of homologous organs in other species are called?
Vestigial Organs
Are the wings of birds and the wings of bats homologous or analogous structures?
They are both. They are homologous because they are both examples of a vertebrate forelimb. They are analogous because they were adapted for flight independently of one another.
