1.      As a result of human activity (such as logging), large forests are becoming fragmented into several smaller forests.

a)      How might the increasing isolation of population in these forests influence their evolution?

b)      How might the fragmentation affect the evolution of a large mammal, like a moose, compared to a small invertebrate, like a worm?

Evolution occurs when there are changes in the frequencies of alleles within a population of interbreeding organisms for example; the allele for black color in a population of moths becoming more common. So if the resources of the forest are breaking up, and group of a species of plant or animal is naturally selected by the environment, and those surviving species interbreed and evolution would be affected that way. Small horned moose might be naturally selected over small horned moose. A worm that survives in warm soil might be naturally selected over a worm that survives in cold soil.
