Although polar bears and grizzly bears aren't all that similar and are definitely separate species, they can interbreed and create fertile offspring in the wild. Hank brings us the story of these misfit bears, which he likes to call...

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 ......

Explore speciation with The Amoeba Sisters. This video discusses sympatric and allopatric speciation and covers several types of isolation types including behavioral, temporal, and habitat isolations. Table of Contents: Intro 00:00...

Sorting organisms into categories seems pretty simple at first, but look a little closer and things get weird.

Paul Andersen explains how reproductive isolation can eventually lead to speciation. Three main barriers to gene flow are included: geographic, pre-zygotic and post-zygotic. Both allopatric and sympatric speciation are discussed. A...

A species is a group of closely related organisms capable of interbreeding and producing fertile offspring, and speciation is the evolutionary process by which new species arise. Speciation can occur through anagenesis (gradual...

How are new species created? An insight into the key evolutionary processes, played out over many generations, which lead to speciation. Biology - Adaptation And Evolution - Learning Points. We all originate from a single cell, so why...

Earlier in the series we learned about evolution by natural selection, and the production of new species, which we call speciation. But did you know there are different types of speciation? There are! That's because there are different...

The question ‘what is a species?’ might sound like a simple one. We have evolved to categorise plants and animals into types, some safe like field mushrooms and other less safe like fly agaric toadstools. We have developed this idea...

Releasing Chinese giant salamanders back into the wild sounds like a good idea, but it's causing problems for the salamanders and for our understanding of what a species even is.

In this video we look at a few keys words that you will come across throughout ecology. An ecosystem is made up of all of the communities that live in it, every single organism from small to big and lots of environmental factors like...
