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
