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

Speciation and Extinction
Paul Andersen details the evolutionary processes of speciation and extinction. Stickleback evolution in Lake Loberg is used as example of rapid speciation. Adaptive radiation is illustrated using the Hawaiian honeycreeper. A brief...
Crash Course
Speciation: Of Ligers & Men - Crash Course Biology
Hank explains speciation - the evolutionary process by which new biological species arise - in terms of finches, ligers, mules, and dogs.
Bozeman Science
Speciation
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...

Stickleback Evolution
About 70 percent of the genes of the stickleback fish are the same as humans. In the video, scholars further explore the stickleback fish and its history, from being removed from Loberg Lake to their change and comeback. Over time, these...

The Origin of Species: Lizards in an Evolutionary Tree
Different islands in the Caribbean have very similar species of anole lizards, which each have their own place in the ecosystem. Researchers did several studies to determine whether the anoles evolved into the different species then...

Formation of New Species by Speciation
Why is Australia home to the world's only population of kangaroos? The answer? Speciation! Biology scholars discover the factors that cause new species to emerge through an engaging video as part of a Fuse School playlist on...

Speciation
Darwin believed species came from other pre-existing species. Now we know it is more complicated than that. The video focuses on speciation and patterns of evolution.
Bozeman Science
Speciation
Viewers see how reproductive isolation can lead to speciation as the narrator of a video focusing on speciation explains the steps to reproductive isolation and addresses both allopatric and sympatric speciation.
Crash Course
Speciation: Of Ligers and Men
Ligers grow at a rate of 2.2 pounds every second day, thus by the end of their first year, they can weigh up to 364 pounds. Ligers are the subject of a video the looks at hybrids and shows viewers how speciation can occur via...
Curated OER
The Origin of Species
Allow Mr. Anderson to assist you in describing how one species can become two through speciation and reproductive isolation. Intended for upper graders, this clip wonderfully explains several complex concepts in a way your class can...

Hhmi: Bio Interactive: The Origin of Species: Lizards in an Evolutionary Tree
In the Caribbean Islands, adaptation to several common habitats has led to a large adaptive radiation with interesting examples of convergent evolution. [17:45]

Khan Academy: Speciation
Learn about speciation, including allopatric and sympatric speciation and mechanisms of reproductive isolation. [10:46]

Bozeman Science: Stickleback Evolution
Paul Andersen describes microevolution and macroevolution in the stickleback fish of Loberg Lake. He describes how anadramous fish repopulated the lake after poisoning and adapted to the new environment through natural selection. He also...
