aren't really flippers anymore. I was looking into some stuff today, and came across these sketches of forelimbs. These are drawings of fossilized hands from three different species of fish / reptiles / amphibians / whatever you want to call them that are intermediate species from when fishes came onto land. It is so neat to look at fossils like these and really see the intermediate stages in the evolution of our kids' and our own limbs. The human hand is without a doubt the most intricate appendage that has ever evolved on the planet, and to see all the changes that had to happen in order for them to form in the way that they did makes me appreciate the fact that I can do stuff like type on a keyboard right now. Bacteria and unicellular animals have got a lot of things that we do not, but hands are still really cool. The bones of hands just like these are becoming hard right now in Becka. It will be cool to hold our babies hand in a few months from now. You know, after her/his hands are cleaned up a bit and aren't all icky anymore. Cause otherwise that would just be gross.
