As girls advance through school, the standardized tests show that their performances in science and math tend to drop gradually. On the other side, the girls tend to show improvements in the social studies. This phenomenon is largely attributed to the evolution, as the female and the main brain tend to have different interests which are largely based on the needs that their ancestors had in the past. The girls tend to perform worse in math and science as they are not really interested in them, nor during the evolution they had any particular reason to have that knowledge. On the other side, they tend to be much better in the social studies, as that is something that they are much more interested in, and that is something that throughout the evolution was very useful to them.
