It’s a pretty safe presumption that hands evolved from fins, since fish evolved long before anything remotely resembling an opposable thumb. Now, a
group of Spanish researchers has demonstrated a genetic expression that hints at how it happened. The group, led by Dr José Luis Gómez-Skarmeta of
Spain’s CSIC-Universidad Pablo de Olavide-Junta de Andalucía in Seville, found that zebrafish injected with a mouse gene, hoxd13, developed
leg-like limbs where fins should be. This indicates that the hoxd13 gene – which occurs in the fish, but at lower levels than in mice – helped
drive the genetic changes that eventually become arms, legs, hands and feet.
Come on! Is this the level science is dropping to in order to once again show evolution?
This is about the dumbest thing I have ever read and I'm curious how funding for stuff like this occurs.
They took material from mice, put it in fish and this gives us an idea about how fish evolved hands?
Sounds like druggie animals swapping needles. Ya, that's how everything evolved.
Oh, did I mention that it was fatal to the fish? Wonder if that's what wiped out the dinosaurs.
Look ma, I grew hands...ack!
