Question

Biologists have found more than 500 species of fruit flies on the various Hawaiian Islands, all apparently descended from a single ancestor species. This example illustrates
a. polyploidy.
b. temporal isolation.
c. adaptive radiation.
d. sympatric speciation.

Accepted Answer

Hey everyone, let's take a look at this question together from a single species, finches in Galapagos island have evolved and diverged into a large variety due to the presence of new habitats. This is considered as what, let's recall what we've learned about the evolution and divergence of a species due to the presence of new habitats. We're talking about the evolution and divergence due to the presence of new habitats. And when we're talking about that, we're talking about adaptive radiation or answer Choice B. Because we know that adaptive radiation has to do with the evolution of a species evolution of species into that wide variety, so into wide variety because of the habitat and in this case a new habitat. So it's basically adapting to that new habitat. And so adaptive radiation is the best term to describe this example we're given and we can also double check our answer because we know that answer. Choice A. Is incorrect because Saint Patrick's speciation is the evolution of a new species from an ancestral species in the same habitat. Answer choice C. Perry Patrick speciation is when a new species is formed in isolation and a hybrid species is when you have two species that form an offspring that has characteristics of both parents. So answer choice B is the only appropriate answer here. I hope you found this video to be helpful. Thank you and goodbye
