Bats and mice and wings and things 18 May 200818 Sep 2017 Comparative limb growth of a bat (top) and a mouse, in utero development. From the paper below. One of my favourite statistics is this: one in every four mammal species you meet is a rat or rodent, and one in every five is a bat. That’s right, nine in every 20 mammal species is covered by one of these taxa: we may as well treat rodents and bats as the standard mammalian species type. So a paper that combines them has to be good. Quintessence of Dust (what a title!) gives an excellent summary and discussion of a paper that tested evolutionary hypotheses of the evolution of bat wings by transplanting bat limb growth genes into mice and observing the result. Both the paper and the post are awesome. And by the way, although in German “bat” is rendered “Die Fledermaus” as every opera buff knows, bats aren’t flying mice. Chiroptera is a whole distinct group from Rodentia. Evolution General Science Species and systematics
General Science Passing thoughts on Rise of the Planet of the Apes 14 Aug 201114 Aug 2011 Spoilers. Look away. As usual Hollywood cannot present how scientists actually do their work. But Rise is a much better film than I expected. For a start, the social dominance behaviours of primates was well presented, along with submission behaviours, threat stares, reciprocal altruism and a host of documented behaviours…. Read More
Evolution Evolution quotes: Diderot 14 Aug 201115 Aug 2011 It seems that nature has taken pleasure in varying the same mechanism in a thousand different ways. She never abandons any class of her creations before she has multiplied the individuals of it in as many different forms as possible. When one looks out upon the animal kingdom and notes… Read More
Administrative Home again 3 Aug 2007 So I’m home from Ish, and the front part of my brain is giddy and tired while the rest has just shut down. I don’t travel well, I’m afraid. One thing that I came back fired up over are the unfinished projects I have running. So I intend to finish… Read More
Well, apparently the French name evolved this way: Latine origine: ?cawa sorix?(owl-mouse) –> turning ‘calves sorices’ in a plural form –> corrupted into bald-mouse (calves is close to “chauve”/bald in French) (source: http://owen.monblogue.branchez-vous.com/2003/6/25/)

Even weirder than “Fledermaus”, chiroptera are called bald-mouses in French (litterally translating). I don’t know why, but I’ll try investigating…

Followed closely by antelopes, right? I do wish that people who think there’s one ladder to the top in evolution would look at some of those taxa. Laurent, “owl-mice” sounds like a good name for bats.
