That way they can get the average result and they're usually more accurate.
The changes in environment can cause the raising of the sea level, which can push animals further inward, which in turn destroy habit, as they began to get clumped together vegetation begins to go away, thus resulting in less species, also hotter climate makes sure that animals with very heavy coats of fur, die out pretty quickly if not cooled (over heating)<span />
Some alleles are dominant while theh other are recessive. A dominant allele has its full effect in the heterozygote
In this population, what will occur is that there will be no evolution. Mutation is neccessary and important because they provide varitations that can result in evolutionary change. Other factors needed for evolution to occur are migration and selective pressure.
