Harmful Protein-Coding Mutations in People arose Largely in the Past 5,000 to 10,000 Years

A study dating the age of more than 1 million single-letter variations in the human DNA code reveals that most of these mutations are of recent origin, evolutionarily speaking. These kinds of mutations change one nucleotide – an A, C, T or G – in the DNA sequence. Over 86 percent of the harmful protein-coding mutations of this type arose in humans just during the past 5,000 to 10,000 years.

Some of the remaining mutations of this nature may have no effect on people, and a few might be beneficial, according to the project researchers. While each specific mutation is rare, the findings suggest that the human population acquired an abundance of these single-nucleotide genetic variants in a relatively short time. (more…)

Sequencing the barley genome will sow many benefits

Some 10,000 years ago, people found they didn’t have to live as nomads, hunting and gathering all their food. In the Fertile Crescent, they started planting crops.

The Fertile Crescent extended from the Nile Valley and along the eastern Mediterranean Coast, through the Tigris and Euphrates valleys of Mesopotamia and down to the Persian Gulf. There, the foundation crops of the Western World were first domesticated. (more…)

New Book Explores Noah’s Flood; Says Bible and Science Can Get Along

“I doubt the historic truth about Noah’s Flood will ever be known with certainty. And I don’t think it really matters. The discoveries of science have revealed the world and our universe to be far more spectacular than could have been imagined by Mesopotamian minds. To still see the world through their eyes is to minimize the wonder of creation.”

David Montgomery, “The Rocks Don’t Lie”

David Montgomery is a geomorphologist, a geologist who studies changes to topography over time and how geological processes shape landscapes. He has seen firsthand evidence of how the forces that have shaped Earth run counter to some significant religious beliefs.

But the idea that scientific reason and religious faith are somehow at odds with each other, he said, “is, in my view, a false dichotomy.” (more…)

Climate Change Led to Collapse of Ancient Indus Civilization, Study Finds

A new study combining the latest archaeological evidence with state-of-the-art geoscience technologies provides evidence that climate change was a key ingredient in the collapse of the great Indus or Harappan Civilization almost 4000 years ago. The study also resolves a long-standing debate over the source and fate of the Sarasvati, the sacred river of Hindu mythology.

Once extending more than 1 million square kilometers across the plains of the Indus River from the Arabian Sea to the Ganges, over what is now Pakistan, northwest India and eastern Afghanistan, the Indus civilization was the largest—but least known—of the first great urban cultures that also included Egypt and Mesopotamia. Like their contemporaries, the Harappans, named for one of their largest cities, lived next to rivers owing their livelihoods to the fertility of annually watered lands. (more…)

Warfare, triggered by political conflict between the fifth century B.C. and the first century A.D., likely shaped the development of the first settlement that would classify as a civilization in the Titicaca basin of southern Peru, a new UCLA study suggests.

Charles Stanish, director of UCLA’s Cotsen Institute of Archaeology, and Abigail Levine, a UCLA graduate student in anthropology, used archaeological evidence from the basin, home to a number of thriving and complex early societies during the first millennium B.C., to trace the evolution of two larger, dominant states in the region: Taraco, along the Ramis River, and Pukara, in the grassland pampas.
