Finches on the galapagos islands express a variety of traits. variability in the offspring of theses finches is a result of

I would say that the variability of these finches is a result of variability of environmental conditions on the different islands of the Galapagos Islands and while these islands are part of the same group, I believe they have enough differences to promote variability of the species.

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
