Meanwhile, the scrawny male sneaks in and mates with her, and he becomes the father of Bambi. The genes for bigger and stronger didn't get passed on there. Suppose that happens time after time. Eventually, the deer will probably be scrawnier-just because they were sneaky. Ok, that's probably enough that you more than get my point.
Evolution is real, and it happens.
We apply that idea to fossils and DNA evidence and decide we think it's pretty likely that our origins as humans lie there. But evolution is not always big and perceptible. Many of us were taught that god created everything. If god created everything, then god is in everything-you, me, the flowers, trees, etc. Maybe god is behind natural selection, that force that determines that it's the scrawny deer that gets lucky in the end.
