00:00Are you part Neanderthal? 7 Unexpected Clues in Your DNA

00:04300,000 years ago, 8 human species existed.

00:10We coexisted and interbred with Neanderthals and Denisovans,

00:14leaving us Neanderthal DNA and genetic diversity.

00:20European descendants may have up to 4% Neanderthal DNA,

00:25affecting traits and disease susceptibility,

00:27revealing our evolutionary past and genetic diversity.

00:34Neanderthal genes increase susceptibility to actinic keratoses,

00:39autoimmune diseases, and skin cancer,

00:42highlighting their incompatibility with today's world.

00:48Neanderthals in Ice Age Europe evolved longer noses for cold, dry climates,

00:54passing these traits to humans and showing lasting adaptive impacts.

01:02Neanderthal genes may predispose us to tobacco addiction,

01:05influencing behaviors once crucial for survival, now causing dependencies.

01:10Neanderthal DNA affected COVID-19 severity,

01:17raising risk for 16% of Europeans,

01:20and showing ancient genes still influence immune response to new viruses.

01:28Neanderthal DNA contributes to strong nails and lush hair

01:32via increased keratin production,

01:34aiding Ice Age survival.

01:40Neanderthals were intelligent,

01:42with larger brains than modern humans.

01:44They created complex tools,

01:46had symbolic concepts and culture.

01:49Interbreeding introduced the microcephaline gene,

01:53enhancing cognitive abilities

01:54and brain efficiency in humans.

01:57Neanderthal DNA boosts immunity against infections,

02:04but heightens allergy risk,

02:06showing benefits and drawbacks of our ancient genetic inheritance.

02:09Historic Presence,
