Our DNA holds thousands of dead genes and we’ve only just begun to unravel their stories. But one thing is already clear: we’re not just defined by the genes that we’ve gained over the course of our evolution, but also by the genes that we’ve lost along the way.
Thanks to these illustrators for their wonderful hominin illustrations featured throughout this episode!

Pretty crazy how the game Ancestors nails this. When “leveling up” your early human you unlock genes that add benefits but you can only keep them past your generation if you spend points to “Lock” them in place. I didn’t realize how accurate that mechanic was until this video.

Elephants don’t eat meat still it gets it’s protein from plants which explains their size, Big cats don’t eat veggies but it still makes vitamins internally. We on the other hand, need all important nutrients- proteins, carbs, fats, vitamins and minerals .

I have an evolutionary question : How come evolution never "invented" a wheel? not in plants, not in animals either, and we humans havent invented anything better for movement Knowing thet evolution has found out about rotation (eyes, knee bones, shoulders...) how come there arent any natural wheels? the dificult part was to invent wings or even legs. Hips, knees or ankles being much more complicated than a wheel Maybe before wheels you first need roads? but wheels came first in fact, or not? or is not that practical after all? Thank you for your videos, very interesting

The evolution explanation is a story, it's a framework in which to hang facts and science. The facts and science stand just fine without the Billions of years, and mutations revealing a phylogenetic tree. The tree is just a way to arrange information and tell a story. The tree is not the facts.

Why did the vitamin c gene die like tf would be really useful
Fundamental Fanatic
Fundamental Fanatic پیش ماه
it just happened, its random mutation. but it didnt affect us much because our diet was rich with vitamin c until we started sailing for long voyages without any fruit on board we also have a gene that makes our muscle growth slower. so we are weaker than other apes. but it was probably required to be able to sustain larger brains instead of huge bodies

I wonder if we start fasting for prolonged periods (days, weeks,months then years) if these genes can be repaired/reactivated? What if we just start living off the land and just eliminate anything that’s man made, can these genes be repaired or reactivated? 🤔

Surprising and scaring at the same time. If food has such a profound impact on mutation which means the current processed and unhealthy food choices will mutant gene in future the way that we will no longer to eat fresh food.

We aren’t omnivorous, we are originally frugivorous just like our ancestors apes or chimpanzees. They also had to consume fruits in order to get essential nutrients as they couldn’t digest cellulose. So because we started eating meat we started to call ourselves omnivorous. But that’s not true if you see our body really has hard time digesting meat too. So about that point what you said here is not completely right.
Fundamental Fanatic

all apes can eat meat. chimpanzees even make hunting parties to kill and eat smaller primates.
