A population of rodents, called population A, lived on a large landmass. One group of the population dispersed to a nearby island. Two million years later, the island population split into two smaller, equalsized populations when a river formed across the middle of the island. Now two new species, A1 and A2, have evolved on the island. They have replaced the population from which they were derived. Use the image to answer the question.Which diagram represents the phylogeny of the populations ...

Natural selection - ANSWER Process that determines which individuals will pass on their genes to the next generation Evolution - ANSWER the changes that we see in the genes and characteristics displayed by successive generations of a population Speciation - ANSWER the production of a new species from a previously existing species Allopatric speciation - ANSWER separated by land Sympatric speciation - ANSWER speciation in the same area; exploiting unused resources causes them to becom...
