Cool example of (not so) Natural Selection

So I've started to watch the Cosmos series with Carl Sagan on YouTube. Already in the second episode there was a wonderful example of (not so) natural selection.

Begins with a back-story in 1/6 and concludes at the start of 2/6.

Cosmos - Part 2: One Voice in the Cosmic Fugue 1/6

Cosmos - Part 2: One Voice in the Cosmic Fugue 2/6

Basically it demonstrates how over time (relatively short time) humans served to select crabs with a certain pattern on their carapace (samurai warrior face) and thus such crabs are far more numerous today.
