How to Make A Humanzee
We all know about inter species animal hybrids - Napoleon Dynamite's favorite animal, the liger, is a typical example. But could a human and our closest primate relative the chimpanzee also breed a living hybrid? Hank explores this ......

Why Genetic Engineering Can’t Do Everything (Yet)
We've made some great strides in understanding the human genome, but before we can tackle genetic engineering, we have some "chicken and egg" problems to figure out.

What Happens If You Fuse All Your Chromosomes? | SciShow News
Two separate groups of biologists reported fusing entire sets of Saccharomyces cerevisiae chromosomes together, and surprisingly, the actual number of chromosomes might not be as important as we thought.

Why Ferns Have More Chromosomes Than You
Chromosomes are fascinating little things, and today, Hank explains why more of them doesn't mean more complex, and why different organisms have different numbers of chromosomes. The short answer: mistakes happen.
