Researchers at Ben-Gurion University of the Negev (BGU) have discovered that gene mutations that once helped humans survive may increase the possibility for diseases, including cancer.

Evolution: New Exhibition at Harvard Museum of Natural History

From humanity’s close relationship to chimpanzees to the missing link between land and sea creatures, the Harvard Museum of Natural History has capped off a year celebrating Darwin and “On the Origin of Species” with a new exhibit that puts evolution front and center.

Human Ancestor Footprints Show Upright Walk

Researchers have discovered a set of footprints they believe go back 1.5 million years. Evidence they say, that man walked upright, something that has always been in question.

Adaptation plays significant role in human evolution

For years researchers have puzzled over whether adaptation plays a major role in human evolution or whether most changes are due to neutral, random selection of genes and traits.

Primate culture is just stone's throw away from human evolution

For 30 years, scientists have been studying stone-handling behavior in several troops of Japanese macaques to catch a unique glimpse of primate culture. By watching these monkeys acquire and maintain behavioral traditions from generation to generation, the scientists have gained insight into the cultural evolution of humans.

Men fighting over women?

Men may usually settle it over a drunken brawl in the pub or perhaps a verbal spat – but new evidence has shown for the first time that fighting over women in prehistoric times could have been worse than that.

Evolution of an imprinted domain in mammals

The normal human genome contains 46 chromosomes: 23 from the mother and 23 from the father. Thus, you have two copies of every gene (excluding some irregularity in the pair of sex chromosomes). In general, which parent contributes a chromosome has no effect on the expression of the genes found on it.

Mummy lice found in Peru may give new clues about human migration

Lice from 1,000-year-old mummies in Peru may unravel important clues about a different sort of passage: the migration patterns of America’s earliest humans, a new University of Florida study suggests.

Adapting to pregnancy played key role in human evolution

The human spine evolved differently in males and females in order to alleviate back pressure from the weight of carrying a baby, according to research spearheaded at The University of Texas at Austin.

Are humans evolving faster?

Researchers discovered genetic evidence that human evolution is speeding up – and has not halted or proceeded at a constant rate, as had been thought – indicating that humans on different continents are becoming increasingly different.

Ancient African megadroughts may drive evolution of humans, fishes

From 135,000 to 90,000 years ago tropical Africa had megadroughts more extreme and widespread than any previously known for that region, according to new research.

The launch of language

If anything sets humans apart from other animals, it must surely be our way with words. For something so ubiquitous, our gift for gab still has strangely obscure roots. The appearance of language has been ascribed to factors ranging from finer control over our voices, the evolution of a grammar module in the brain, even the shift to a meat-based diet that fuels more gray matter.
