Hank talks about the issues of rising global population.

Birds fly south, humans bundle up, but what do insects do to survive the winter? From creating antifreeze-like alcohols to burrowing in the ground, bugs have a few solutions to carry on.

It sounds like something out of a sci-fi movie: a new crayfish population made entirely of asexually reproducing, all-female clones. But is it a new species?

What if you could just drop your kids off at someone else’s place and let them have the responsibility? Well, there are some animals that do just that. They’re called brood parasites, and they lay their eggs in other animals’ nests and...

Paul Andersen explains the current classification system that we use in Biology. He starts with a brief history of taxonomy. He explains how the goal of classification is to reflect evolutionary relationships. He then explains how...

Seymour might have had better luck had he raised one of these Bornean plants instead of a giant Venus flytrap. Instead of evolving to eat animals, they’ve evolved to play nice in exchange for their nutrient rich feces.

We know how to clone animals, so why aren't we saving endangered species by cloning their populations?

You probably have a vague idea of what sperm does, but not all sperm are created equal, and some have even developed unique adaptations to get where they're going.

Plants are constantly under attack. They face threats ranging from microscopic fungi to small herbivores like caterpillars, up to large herbivores like elephants. But plants are ready, with a whole series of internal and external...

How does one species evolve into two within the same habitat? Discover the details behind a rare type of evolution: sympatric evolution.

Hank continues our exploration of animal phyla with the more complexly organized annelida and arthropoda, and a biolography on insects.

In this video Paul Andersen explains how biodiversity measures the variety of genes, species, and ecosystems on the planet. Biodiversity provides resources and ecosystem services for humans on the planet. He also explains how...

If you want to be able to breathe underwater, you're going to need to get creative. So some turtles, dragonfly nymphs, and sea cucumbers decided to use their butts.

In the world of ecology, the only constant is change - but change can be good. Today Hank explains ecological succession and how ecological communities change over time to become beautiful, biodiverse mosaics.

Hank tells us the background story and explains the importance of the science of classifying living things, also known as taxonomy.

Is love a signal winding through your neural pathways? A cliche? A cult? Love is easy to compare but difficult to define, maybe because we're fundamentally biased; we try to define love while falling in or out of it. And love feels...

Do you like drinking milk or chatting with your friends? Well, you can enjoy those because of the evolution happened over the past million years, and we are still evolving. Let's find out what will we be like in the future with us!

From something as small and complex as a chromosome to something as seemingly simple as the weather, sex determination systems vary significantly across the animal kingdom. Biologist and teacher Aaron Reedy shows us the amazing...

Some plants have very unique ways to disperse their seeds. Olivia introduces 5 of the most bizarre seeds in the world!

Scientists found a species of wheatgrass that is resistant to fungus, but how it became resistant is both surprising and unclear.

Houseplants can be great for your mental health, but eating some of them can be far worse for your bodily health than you might think.

Paul Andersen explains the importance of biodiversity. He starts by describing how biodiversity can be species, genetic or ecosystem diversity. He explains the importance of keystone species in an environment and gives two examples;...

With the non-avian dinosaurs extinct, it was time for mammals to take over. Finally, in the tiniest sliver of the history of life, humans emerge.

Corals in the Pacific Ocean have been dying at an alarming rate, particularly from bleaching brought on by increased water temperatures. But it's not too late to act, says TED Fellow Kristen Marhaver. She points to the Caribbean -- given...
