That's not hyperbole. I really mean it. How else could I react when I open up the latest issue of Bioessays, and see this: Cephalopod origin and evolution: A congruent picture emerging from fossils, development and molecules.
Cats and humans look very different. Or do they? 32-day old embryos of the two species look pretty identical. Why do they look so similar? This is one of the oddest riddles in biology, which has now been given a new answer following the publication of two articles in Nature today.
When last we left this subject, I had pointed out that the phenomenon of embryonic similarity within a phylum was real, and that the creationists were in a state of dishonest denial, arguing with archaic interpretations while trying to pretend the observations were false.
Parler du sujet des plumes de dinosaures me renvoie au moment critique dans ma vie où j'ai découvert la discipline dans laquelle je travaille actuellement et dans laquelle je compte travailler jusqu'à la fin de mes jours : l'Evo-Devo.
