Flies are evasive buzzing machines that make it nearly impossible to swat. Luckily, science has some explanation to help you predict their next move.

At SciShow, we ask the tough questions. Today we explore the answer to the question "if identical twin brothers married identical twin sisters, would their offspring be identical?"

You might think your grandma who wakes up at 4am just needs less sleep than younger people. Not so! Studies suggest there are some bizarre reasons older people rise at the crack of dawn, including something called brain sand!

Everyone knows the name Charles Darwin, but his lesser known frenemy, Alfred Russel Wallace, was developing a lot of the same ideas around the same time.

Louise Leakey asks, "Who are we?" The question takes her to the Rift Valley in Eastern Africa, where she digs for the evolutionary origins of humankind -- and suggests a stunning new vision of our competing ancestors.

The name of the order Carnivora means "meat-eaters," and while most of the members of Carnivora live up to that name, there is at least one cute and curious exception.

Paul Andersen explains the importance of selection in biology. Artificial selection occurs when humans choose traits that will be selected for or against. This has created the variety of domesticated animals and crops. He then describes...

Antler cells divide really fast, and with their super-fast growth, antlers resemble tumors in some ways. But animals in the deer family are less likely to get cancer than many other organisms, and a recent genetics study may have...

So you know about Freshwater and Saltwater now and you know that there's not that much Freshwater for us (and other life) to get to. So how do different animals deal with different amounts of water where they live? In this episode of...

Blue whales are the largest animals on the planet, but what helps them grow to the length of a basketball court? Asha de Vos explains why the size of krill make them the ideal food for the blue whale -- it's as if the blue whale was made...

Hank comes to you from his inner sanctum of science news to bring you a couple of things you never knew about human origins, the latest from his best friend on Mars, and what you can do to help one of the craziest, greatest people in the...

Convincing a predator to attack you might seem like a bad idea, but Trinidadian guppies have a whole bag of evolutionary tricks to help them do just that. But why do they do it, and how does it help them survive?

The species of slug known as Elysia chlorotica may not look like much— it resembles a bright green leaf— but it's one of the most extraordinary creatures on our planet. Living in marshes along the coast of North America, it can go about...

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 brief...

Emily Graslie joins us to share the wonder of how shoulders, humble as they may be, have played a huge role in the evolution of mammals the world over. Thanks to the Museum of Comparative Zoology at Havard and The Field Museum for...

This is part 3 of 3 in my series about how our bodies evolved to look like they do.

Organisms have evolved many clever forms of armor so that they can be ready for whatever nature throws at them. And us flimsy humans can learn to enhance our armor by taking inspiration from some of these creatures, and not necessarily...

Wouldn’t it be cool to be able to point at a fossil and know that it’s the first, say, plant? Well... yeah! But it's not that easy! Scientists are always making new discoveries that throw all our old assumptions into question, but we've...

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...

There are fossils of viruses, of sorts, preserved in the DNA of the hosts that they've infected. Including you. This molecular fossil trail can help us understand where viruses came from, how they evolved and it can even help us tackle...

It turns out life may have gotten its start pretty early in Earth's history, and while the first couple billion years saw several important developments, the period was still dominated by very simple life forms. This is our first...

Elephants are huge, so you might think all those extra cells would mean more cancer, but scientists have some new insights into why this is isn't the case.

When you picture a single cell, you probably imagine something super tiny that you had to look at through a microscope. But, there are some huge exceptions to this rule. And we really do mean huge. Chapters Stentor coeruleus 1:27 Gromia...

Drone technology has advanced a lot in the last few decades, but our flying robots still have a lot to learn about navigation, agility, and adaptability from animals that have been flying for millions of years.
