The video explains the concept of the pentadactyl limb, which is a limb with five digits, found in all four-limbed vertebrates. The video provides examples of how the pentadactyl limb has been adapted to suit different uses in various...

Brit looks back on our sixth month on Nature League, when we explored the theme of evolution and speciation. Get your Nature League pin here!

This video discusses Charles Darwin's theory of evolution and how it was received at the time it was published. It starts with Darwin's observations during his world expedition in the 19th century, particularly on the finches of the...

Explore the fascinating world of animal adaptations, where species develop physical and behavioral traits to thrive in their environments. Discover how sharks, bears, raccoons, and other animals have evolved to fit their habitats, from...

Snowshoe hares face shrinking snowy habitat, but because some populations have a mix of genes for coloration, they may adapt to the changes in their environment. ➡ Subscribehttp://bit.ly/NatGeoSubscribe' target='_blank'...

This video explains the concept of speciation and how it occurs through natural selection and adaptation. It highlights the importance of isolation in promoting speciation, using the example of the Galapagos Islands and their endemic...

This video discusses the concept of adaptations in animals and how they help them survive in their environments. It explores examples such as the physical adaptations of sharks and the behavioral adaptations of bears and raccoons. The...

Explore the concept of natural selection, a cornerstone of evolutionary biology, through Charles Darwin's groundbreaking work. Learn how Darwin's observations of finches and other species during his voyage on the HMS Beagle led to his...

Genetic variation produces new characteristics and, over generations, drives the evolution of species. But how do new gene types arise and what are the processes behind evolution? Biology - Adaptation And Evolution - Learning Points....

Explore the concept of adaptations, crucial for the survival and evolution of species. Learn how organisms develop physical and behavioral traits in response to environmental changes. Understand the importance of adaptations through...

How does evolution really work? Actually, not how some of our common evolutionary metaphors would have us believe. For instance, it's species, not individual organisms, that adapt to produce evolution, and genes don't "want" to be passed...

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...

Charles Darwin’s Theory of Evolution is perhaps the most famous, and certainly the most controversial, scientific theory ever developed. First published in 1859 in a book titled, On the Origin of Species by Means of Natural Selection, or...

The adaptations of predators and prey are vital for their survival, and help to drive the evolution of species. Biology - Adaptation And Evolution - Learning Points. Predators are animals that kill other animals for food - their prey....

In the past 3,000 years, many populations have evolved genetic adaptations to their local environments. People in Siberia and the high arctic are uniquely adapted to survive extreme cold. The Bajau people can dive 70 meters and stay...

With rising temperatures and seas, massive droughts, and changing landscapes, successfully adapting to climate change is increasingly important. For humans, this can mean using technology to find solutions. But for some plants and...

You're probably aware that nature has come up with some pretty fascinating animal adaptations over the millennia, and in general, the stranger the adaptation, the more important it is to that organism. Today on SciShow News, Hank has...

We tend to think of evolution as a slow, gradual process playing out over millions of years. But evolutionary biologist Shane Campbell-Staton says nature is now changing at breakneck speed to keep up with the world humanity has built....

In this video Paul Andersen defines adaptations and explains how organisms can become better adapted to their surroundings using the process of natural selection. Specific examples of adaptations, like coat color in rock pocket mice, as...

Hank explains where that over-simplified image of evolution comes from and what it is actually supposed to mean.

With their squishy bodies and color-changing abilities, octopuses and other cephalopods already look like our planet’s resident aliens. But researchers have discovered yet another thing that separates them from most other animals on Earth!

A summertime look at why we sweat, why we burn, and why our fingers wrinkle in the pool

What happens when you don't sleep? And why do we need to do it anyways? Hank explains the science of sleep: the cause, the benefits, and who holds the record for going without it!
