I know you’re thinking we’ve had more than enough discussion of one simplistic umbrella hypothesis for the origin of unique human traits — the aquatic ape hypothesis — and it’s cruel of me to introduce another, but who knows, maybe the proponents of each will collide and mutually annihilate each other, and then we’ll all…

After our disastrous chick lab — it turns out that getting fertilized chicken eggs shipped to remote Morris, Minnesota during a blizzard is a formula for generating dead embryos — the final developmental biology lab for the semester is an easy one. I lectured the students on structuralism and how there are more to cells…

Today was the last day I lecture at my developmental biology students. We have one more lab and one final class hour which will be all about assessment, but this was my last chance to pontificate at them…so I told them about all the things I didn’t teach them, and gave them a reading list…

It’s another exam day!

It’s a frog tadpole with an eye surgically grafted to its trunk! Wait, this is an old story — similar experiments were done at least 20 years ago. You can transplant developing eyes to the tadpole, but the cool thing is that the donor optic nerves will grow into the sensory tracts of the dorsal…

Learn a little developmental biology

This is a cool video from a textbook publisher (Molecular Biology of the Cell, a very good text) illustrating how Spemann/Mangold’s famous organizer experiment was done. Also cool: those are apparently Edward De Robertis’ hands doing the experiment.

The argument from eyelid development

This is a new one for me. Earlier today I was summoned on Twitter to address an assertion by a creationist, @jarrydtrokis. I was slightly boggled. He was baffled by eyelid development. It seems he thinks it requires…intelligent design!. … Here’s one for you to ponder Eye lids in the womb… How are they formed?…
