Explore the concept of biological evolution with the Amoeba Sisters! This video mentions a few misconceptions about biological evolution before providing a general definition. Then this video provides a description of four different...

Scientists have discovered a group of three closely related flowers that seem to break the laws of genetics. These mountain beardtongues are pollinated by either bees or butterflies, but not both, and that's the key to an incredibly...

Chromosome shenanigans have resulted in some unexpected hybrid fishes. Also, this record-breaking mouse lives at a ridiculous altitude.

You know that thing you've been putting off for awhile, that could probably be done now but instead not doing 'cause it doesn't sound like fun' right now? Well here's an explanation as to why you probably feel that way. So stop...

Earlier this week, a team of researchers announced that they’d made a discovery about how we inherit mitochondrial DNA from our parents that could change what we know about not only disease inheritance, but human history as a whole.

Trauma doesn't just affect the person who originally experienced it. It can also be passed down to their children and grandchildren.

The first time you visit a new doctor, they’ll probably ask you about your family history - but it turns out that family history doesn’t tell you everything about the risks that can be hidden in your genes.

What would you do if you found out that cancer could be lurking in your genes? More people are getting news like that these days as more kinds of cancer are being linked to specific genes and genetic tests let doctors screen your...

Scientists estimate that about 2% of our DNA is from Neanderthals. In this week, the journal Cell showed what those Neanderthal DNA do to our genome.

This week in SciShow News, Hank tells us about some weird science, including a squid that's not a squid, animals that can talk, and new insights into how you can mess up your body much faster and for much longer than you ever thought...

Dimples! They're so cute, but surprisingly mysterious! What causes them naturally and how can we make them happen?

Why does the Earth spin? Does a basketball falling from a spinning merry-go-round fall in a curve, as it appears to, or in a straight line? How can speed be manipulated while spinning? In short, why is the spinning motion so special?...

The sequence of DNA that we inherit from our parents encodes directions for making our cells and giving us specific traits. Identical twins have the same DNA sequence, so how can one twin end up with a genetic disorder while the other...

Everyone is afraid of something, and traditionally, we’ve thought that fears are learned. But the key to understanding some fears could lie in our DNA.

Humans are special, and we got that way thanks to evolution and natural selection. The proof is right there in our bodies! From anatomy to genes, here are some stories of how you got to be the way you are.

Explore DNA structure/function, chromosomes, genes, and traits and how this relates to heredity! Video can replace old DNA structure & function video and in addition covers foundational concepts of heredity. Table of Contents: Video...

Hank explains the little we know about the perceptual condition known as synesthesia, where a person involuntary associates one sensation or experience with another sensation.

Until the early 20th century, Tasmania was home to a very weird wolf-like creature. Except that it wasn't a wolf. Even though it looked like a wolf. How did that happen? Here's the science of convergent evolution!
