all the top bones are the same shows

Common ancestor

Which field of study, providing evidence for evolution p, is represented by the similarity in bone among these 3 organisms?

Comparative anatomy

As these embryos mature, they will most likely

Develop the distinctive characteristics of their species

Which two species are most closely related

E and I

Which statement is in agreement with Darwin's theory of evolution

More offspring are produced than can possibly survive

Variation within a species are most likely the result of

Mutations and sexual reproduction

Birds diagram shows which processes

Natural selection

In an environment that undergoes frequent change, species that reproduce sexually may have an advantage over species that reproduce asexually bc sexually reproducing species produce..

Offspring with more variety

penguin question

Result in an increase in black penguins over time if the trait provides a reproductive advantage

According to the theory of natural selection, why are some individuals more likely than others to survive and reproduce

Some individuals are better adapted to exist in their environment than others are.

Which concept is shown in the leave diagram

Survival of the fittest

A weakness in Darwin's original theory of evolution was the

The genetic basis for variation was not explained

Darwin's theory of evolution is based on

Variation and natural selection

The modern theory of evolution states that a basis for variation within a species is provided by

mutations

Since variations between offspring are important tin the process of natural selection, evolution would be expected to occur more rapidly in species that reproduce bu the process of 1)budding 2)asexual reproduction 3)sexual reproduction 4)sporulation

sexual reproduction

Evidence that best supports the theory of biological evolution was obtained from the

study of fossil records

Which characteristic is necessary for natural selection to occur in a species

variation
