An interesting short piece in Popsci about swallows getting better at not dying from being hit by cars. Now, most of the stuff published in Popsci is junk, so I suspect this is junk, too. Regardless, there is a fact: the birds are dying less; and it is interesting to think about why that might be.
Evolution is the key to survival. So why is it that many people think that the world, right as it is today, is the best world and the world worth preserving?
