I'm not nearly educated enough about this subject to try to summarise it, but the research being carried out by Michael Levin's group into how organisms control anatomy growth is completely fascinating and has the feel of a breakthrough. Almost all the talks I've seen are good, for example:
This one is the winner for me in the thread. I saw a video of it a while ago and I was fascinated by the idea that voltage differences are the way the DNA gets expressed. Yet nobody seems to be taking about the bioelectrical science of it except for this small academic crowd.
I am also not nearly educated enough, and also following this work very closely. With the strides made in the past several years I'm always surprised I don't see it being discussed more (outside of a niche of academics)

Creating new species without genetic changes seems wild!
