۲۱ دی ۱۴۰۰۱۰ دقیقه۰٫۰

Around 10,000 years ago, somewhere in Africa, a microscopic parasite made a huge leap. With a little help from a mosquito, it left its animal host - probably a gorilla - and found its way to a new host: us.

The Snake Detection Hypothesis proposes that the ability to quickly spot and avoid snakes is deeply embedded in primates, including us - an evolutionary consequence of the danger snakes have posed to us over millions of years.

We often think of dinosaurs as either preying on other dinos or mammals, or as plant-eaters -- but in ecosystems today, those aren’t the only two options. So why would we expect dinosaurs to have only been carnivores or herbivores, with the occasional omnivore thrown in the mix?

As revolutionary as teeth were, they would go on to disappear in some groups of vertebrates. But why?

قسمت ۵

‫قسمت 5

۲۷ بهمن ۱۴۰۰۱۰ دقیقه۰٫۰

Do our modern horses descend from just one domesticated population, or did it happen many times, in many places? Answering these questions has been tricky, as we’ve needed to bring together evidence from art, archaeology, and ancient DNA…Because, as it turns out, the history of humans and horses has been a pretty wild ride.

۴ اسفند ۱۴۰۰۱۰ دقیقه۰٫۰

Today, all mammals from humans to bats have five fingers or fewer. Yes, even whales, whose finger bones are hidden in their fins. Birds have four or fewer and amphibians get the best of both worlds, often having four digits on their “hands” and five on their “feet.” But no species of vertebrates have more than five digits, let alone eight!

قسمت ۲۴

‫قسمت 24

۲۴ فروردین ۱۴۰۱۸ دقیقه۰٫۰

We tend to think that evolution only goes in one direction— toward getting bigger and more advanced. But that’s not always the case. This tiny, simple animal, the Myxozoans, (yes, animal!) evolved from something bigger and more complex.

While sour taste's original purpose was to warn vertebrates of danger, in a few animal groups, including us, its role has reversed. The taste of danger became something it was dangerous for us to avoid.

قسمت ۲۷

‫قسمت 27

۷ اردیبهشت ۱۴۰۱۱۰ دقیقه۰٫۰

Only a handful of Denisovan fossils have been identified. In the absence of actual body fossils, it’s impossible for us to reconstruct their morphology, right?

While we’ve been farming for around 10,000 to 12,000 years, the ancestors of ants have been doing it for around 60 million years. So when, and how, and why did ants start … farming?

قسمت ۳۲

‫قسمت 32

A mysterious, large feline roamed Eurasia during the last ice age. Its fossils have been found across the continent, and it’s been the subject of ancient artwork. So what exactly were these big cats?

قسمت ۳۳

‫قسمت 33

۵ خرداد ۱۴۰۱۸ دقیقه۰٫۰

Fossil evidence suggests Diictodon used burrows to breed, and that a parent stayed behind to feed and protect their young. And the parent that stayed behind? It might’ve been the male.

قسمت ۴۰

‫قسمت 40

۲۵ خرداد ۱۴۰۱۱۱ دقیقه۰٫۰

Paleodictyon, a hexagonal-patterned fossil, is a bit of a mystery. We don’t even know if it’s a trace fossil, or the organism itself. So… what could it be?

قسمت ۴۱

‫قسمت 41

In 2003, microbiologists made a huge discovery. One that would force us to reconsider a lot of what we thought we knew about the evolution of microbial life: giant viruses.

قسمت ۴۶

‫قسمت 46

۳۰ تیر ۱۴۰۱۱۴ دقیقه۰٫۰

Despite the profound changes we’ve made here in recent history, the epic saga of Los Angeles' natural history is still visible - and even striking - if you know where and how to look for it.

قسمت ۴۷

‫قسمت 47

۶ مرداد ۱۴۰۱۱۱ دقیقه۰٫۰

Today, billions of people around the world start their day with caffeine. But how and why did the ability to produce this molecule independently evolve in multiple, distantly-related lineages of flowering plants, again and again?

قسمت ۵۳

‫قسمت 53

۲۷ مرداد ۱۴۰۱۱۱ دقیقه۰٫۰

Mystacodon is the earliest known mysticete, the group that, today, we call the baleen whales. But if this was a baleen whale, where was its baleen? Where did baleen come from? And how did it live without it?

قسمت ۶۳

‫قسمت 63

۵ مهر ۱۴۰۱۱۲ دقیقه۰٫۰

Mercury, Venus, and Mars are all super low on water – so where did ours come from and why do we have so much of it? We think our water came from a few unlikely sources: meteorites, space dust, and even the sun.
