Blog 3: Explain what microevolution is? What are the three ways that variation occurs?

Microevolution is a change in gene frequency within a population. In genetic variation there are three ways it can occur. The first one being when the crossing over happens during meiosis, or when new alleles are favored during natural selection, and there is also the recombination of chromosomes that occur during sexual reproduction, also known as independent assortments.

An example of microevolution:

Blog 2: Why is fossil record hard to interpret

The fossil record is hard to interpret because there are many organisms living and that have lived. In order to match a fossil to an organism or species you must find all the fossils that make up the species, or that would make it easier anyway. To interpret a fossil you must be very careful and gentle because of how fragile they are. It is also very hard to distinguish closely related fossils because of how a like the remains can be.
