Some people wake up energized at 5 a.m.
Others feel like zombies until noon.

But what if that wasn’t laziness… what if it was evolution?

In this video, we explore the evolutionary science behind early birds, night owls, and the people in between — and why your sleep schedule may have helped keep ancient humans alive for over 300,000 years.

From teenagers who naturally stay up late, to grandparents waking up before sunrise, your internal clock may actually be part of an ancient survival system built into human tribes.

We’ll also look at fascinating research on the Hadza hunter-gatherers of Tanzania, one of the last remaining hunter-gatherer societies on Earth, and how their sleep patterns reveal something shocking about human evolution.

If you've ever struggled with mornings, felt guilty for sleeping late, or wondered why your brain seems wired differently than other people… this video is for you.
