Question

If there are no differences between the amino acid sequences in the cytochrome c protein of humans and chimpanzees, why aren't we the same species?

Answer 1

the other nitrogenous bases in our dna are in a different order, and so code for differenr amino acids, creating different characteristics. also cytochrome c is in every organism so it is possible we share sequences with other species

Answer 2

Answer:

D. The lineage containing moths diverged longest ago from the rest of the species represented in the table

Explanation:

The lineage containing moths diverged longest ago from the rest of the species represented in the table. Since moths, invertebrates, have the greatest number of amino acid differences for cytochrome c, they likely diverged longest ago. If you draw out the cladogram, humans and monkey are closely related, turtles and chickens are closely related, and moths are the first to diverge.
