Two nucleotide sequences (DNA) found in two different species are almost exactly the same. This suggests that these species...
are evolving into the same species.
may have similar evolutionary histories (share a common ancestor).
have the same number of mutations.
Whales and snakes both have tiny leg bones that are not visible or used. This would suggest that...
both evolved from animals that had legs.
leg bones are not necessary.
whales and snakes are related.
The human embryo and embryos of all other animals with backbones have gill slits as they develop as an embryo before they disappear (depending on the species). This information best supports the idea that...
all animals with gill slits are related.
dogs are our closest relative.
dogs are in the same species as humans
