Speciation, which produces variety
they all digest food and it comes out the anis *improved answer* actually it's spelled anus. He studied finches and the different types of beaks the finches had, which led him to find the evolution theory.
tortiose and finch.(Galapagos Islands
Divergent Evolution Pvt Locklear was here ;)
DOnt know the answer? GET HELP WIERDO
Probably gradualism as they have not seemed to change much and have not split to give rise to new species. Stabilizing selection keep this organism evolving slowly.

divergent evolution i think

Geographically isolated and without competition from similar species, these finches developed distinctive anatomy (particularly beak size and shape) and behaviors, with each species exploiting a unique feeding niche. The bill is adapted in the different species for different purposes, such as crushing seeds, pecking wood, and probing flowers for nectar. The woodpecker finch, Cactospiza pallida, an insect-eater, holds twigs and cactus spines in its beak to fish out larvae in tree cavities. Darwin proposed that the Galapagos finches evolved on the islands from a single species of finch from mainland South America. Modern methods of DNA (genetic) analysis have confirmed his insight. Darwin's finches are classified in three genera of the phylum chordata, subphylum Vertebrata, class Aves, order Passeriformes, family Fringillidae, subfamily Geospizinae.
Environmental changes influenced speciation
Analogous evolution. Convergent evolution.
yeah sure why not
I think they are called this because their tail is black and white... just a guess though! Good guess and you are close... If you look closely at the male on his upper chest is a zebra stripped pattern of black and grey...
Basically, a unit of pattern in evolution means that the more closely related two (or more) species are, the more structurally similar they would be to each other.
Punctuated equilibrium is the name of that pattern.
