Did Humanity Almost Go Extinct? Population Crash Theory Explained

This chart shows human brains size over time. They got way bigger, fast. But now they’re shrinking? (No, it’s not the phones!) About 2 million years ago something changed and it altered the course of human evolution. Our brains just started RAPIDLY growing, the organ nearly doubled in size in just a few hundred thousand years. This turning point is what allowed us to evolve into the intelligent species we are today. But now… To learn more, follow along! #evolution #human origins #science

Учёные создали эмбрион из клетки кожи и сперматозоида. Они взяли ядро с ДНК из клетки кожи, поместили его в яйцеклетку без собственного ядра и оплодотворили. Это значит что теоретически двое мужчин могут зачать генетически родного ребёнка. Технология ещё не готова к широкому применению, но в будущем может изменить лечение бесплодия для всех. #наука #медицина #генетика #технологии #будущее
