Evolution vs. Selection

Swallows have evolved? http://www.newscientist.com/article/dn23288-birds-evolve-shorter-wings-to-survive-on-roads.html More likely, there has been selection via automobile. There is a distinction between evolution and selection, which seems to be lost of media. Selection drives evolution, but evolution is on a long time scale.

Shorter wings work better in dodging cars; therefore, birds with shorter wings reproduce more, and propagate the genes for shorter wings. QED

The unanswered question to me is the energy cost of shorter wings per weight. Perhaps there are more bugs?

かえるのうた, frog song

おもったよりちがう。
So, my Japanese film for the day ended up being soft porn.
Frog Song has a few interesting things going for it, but not really enough to be redeeming. 20 seconds of two girls fighting it out with baguettes is about it.
