Only a handful of Denisovan fossils have been identified. In the absence of actual body fossils, it’s impossible for us to reconstruct their morphology, right?

Did you know that your environment and lived experiences can actually affect your DNA? Welcome to the world of epigenetics! In this fun episode of SciShow, Hank & his clone Circus Hank explain the power of epigenetics, which studies the...

You know all about how DNA bases can code for an organism's traits, but did you know there's more influencing phenotype than just the bases? Explore epigenetics with the Amoeba Sisters by learning about a few types of epigenetic marks...

If you plant a seed from your orange, you might have to wait as long as 15 years to get a tree with fruit, which is kind of a bummer for the impatient types among us. Fortunately, there’s an age-old trick called grafting that can shorten...

Here's a conundrum: Identical twins originate from the same DNA ... so how can they turn out so different - even in traits that have a significant genetic component? Carlos Guerrero-Bosagna explains that while nature versus nurture has a...

Hank & his clone Circus Hank explain the power of epigenetics, which studies the factors that determine how much or whether some genes are expressed in your body.

Obesity and the health problems it brings with has long been seen as a product of genetic predisposition and bad life style choices. But the foetal susceptibility hypothesis introduces another cause, the nourishment an embryo receives...
