In this two part conversation, I am joined by Dr. Jeff Hardin, a zoologist at the University of Wisconsin and co-author of the textbook World of the Cell. In part 1, we spend most of the discussion on the amazing and sometimes mind-boggling science of the embryo, including splitting an embryo to create two or more fully developing individuals, two or more embryos merging to form one chimera, trans-species chimeras, glow-in-the-dark cells, gene editing, clones, and designer babies. With lots of mention of movies and sci fi!
