Human Ancestors

Scientists analyzing modern genomes may have discovered a long-lost branch of the human family tree, suggesting that everyone alive might carry DNA from a 'ghost lineage' of human ancestors.

Scientists have made a breakthrough in understanding human right-handedness, attributing it to two major evolutionary shifts: walking on two legs and developing larger brains. This discovery suggests that as human ancestors evolved, their preference for using their right hand intensified. The study sheds light on one of humanity's most distinctive traits.
