Many male organisms exhibit traits that, intuitively, should be disfavored by selection. From the massive peacock tail fan to guppies with brightly colored tails, it would seem that selection should have weeded out traits that make the organism more vulnerable to predators. However, selection has preserved these traits instead, through a special type of selection called sexual selection. At least this is the standard theory presented by the Darwinists. Parts of it may be accurate, parts may be inaccurate. We’re going to spend some time in 2021 looking at sexual selection, pulling out the meat, and spitting out the bones.
