Natural selection in human populations continues today, and scientists are studying the prospects for its influence on human genes
Scientists have discovered that natural selection is happening right now among humans high in the mountains of Nepal. The physiological traits that help Tibetan women survive at high altitude are being selected for within the population, meaning they could become more common. The people of Papua New Guinea, who have been genetically isolated for millennia, carry unique genes that help them fight off infections, and some of these genes come from our extinct human cousins, the Denisovans. Hundreds of human genes have been affected by natural selection over the past 3,000 years.
New facts in the history of Ancient Egypt have been discovered
It would seem that Egypt has been dug up and down, but archaeologists and scientists are finding new facts to study. For example, mysterious plasma bubbles have appeared above the pyramids; China has recorded these strange atmospheric phenomena using modern radar. Archaeologists have discovered a 3,000-year-old fort in the desert, which contains evidence of the pharaoh’s stay. The ancient Egyptians used so much copper that they polluted the harbor near the pyramids.
Archaeologists have discovered a 4,000- to 5,000-year-old ceremonial temple in a sand dune in Peru
Archaeologists recently discovered the lost ruins of a ceremonial temple buried in sand and estimated to be between 4,000 and 5,000 years old in northwestern Peru. The team first discovered the walls, then uncovered a series of features that suggested the structure had once been a temple. Then came the skeletal remains of three adults, hidden between the walls.
