What pattern of evolution is shown by the Galapagos finches?

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.

A pattern of evolution that results when two unrelated species begin to appear similar because of environmental conditions is?

Analogous evolution. Convergent evolution.

yeah sure why not


Why are zebra finches called zebra finches?

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...


What does unity of pattern mean in evolution?

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.


Pattern of evolution where a spicies is stable for a long time then rapidly changes?

Punctuated equilibrium is the name of that pattern.
