Fruit trees are unpredictable and grow slowly, and consumer tastes are fickle, so successful new varieties of fruit are rare

We don't know which living thing was the very first to arrive at the totally revolutionary process that is sexual reproduction but we can follow the history of how (and why) sex became a thing.

For the first time, researchers have observed two cases of asexual reproduction in condors. And it also turns out that whales are much hungrier than we thought.

Hank talks about population genetics, which helps to explain the evolution of populations over time by combing the principles of Mendel and Darwin, and by means of the Hardy-Weinberg equation.

Hank explains the evolutionary basis for altruistic behavior in animals, including vampire bats!

In this video Paul Andersen explains how variation is created in a population over time. Variation in offspring is caused by genetic recombination, mutations and environmental effects. Parental DNA is recombined using the process of...

Science, while often the result of a stroke of genius, can just as easily be a stroke of extraordinarily good luck. Mendel’s work just happened to be a mix of the two.

Paul Andersen explains important concepts that can not be explained by simple Mendelian genetics. He begins with a discussion of polygenic inheritance and uses a simulation on height to show how a bell shape curve of phenotypes is...

Evolution is particularly vulnerable to misunderstandings around the scientific language. SciShow clears up some confusing language!

Population ecology is the study of groups within a species that interact mostly with each other, and it examines how they live together in one geographic area to understand why these populations are different in one time and place than...

In the search for longevity, scientists have found the longest-lived vertebrates on the planet in the arctic. Meanwhile, in warmer climes, the FDA approves a new method for combating disease-carrying mosquitoes.

Hank guides us through the process of natural selection, the key mechanism of evolution.

New ReviewCaecilians are legless amphibians. Some of them are immune to cobra venom and in a certain sense, some of them eat their mothers from the inside-out and some eat them from the outside-in.
