Roadkill Forcing Cliff Swallows To Evolve 387
sciencehabit writes "Cliff swallows that build nests that dangle precariously from highway overpasses have a lower chance of becoming roadkill than in years past thanks to a shorter wingspan that lets them dodge oncoming traffic. That's the conclusion of a new study based on 3 decades of data collected on one population of the birds. The results suggest that shorter wingspan has been selected for over this time period because of the evolutionary pressure put on the population by cars."

...And this is yet another proof that God exists. My prayer circle has spent the last 10 years asking for Divine intervention to halt the senseless deaths of road-adjacent animals. Thanks to our unceasing intervention, He knew to trim a wee bit off the tip of every bird's wings (gradually, of course, so that mommy birds would still recognize their babies - and left longer wings on the sinner birds so that they would die and serve as a warning to others). Praise Jesus!

these evolutionists are just trying to force these lies down your throats.
how can the birds be changed by the overpasses? the bible tells us that the overpasses have existed since the creation of the universe, 3 decades ago.

It was trying to do you a favour: cut the coconut in half, bang the halves together and you'll not need to pay for a car anymore.
