Maize (Corn) May Have Been Domesticated In Mexico As Early As 10,000 Years Ago

ScienceDaily discussed new findings about the domestication of maize in Mexico.

Now, in addition to more traditional macrobotanical and archeological remains, scientists are using new genetic and microbotanical techniques to distinguish domesticated maize from its wild relatives as well as to identify ancient sites of maize agriculture. These new analyses suggest that maize may have been domesticated in Mexico as early as 10,000 years ago.

Early Americans Arrived Thousands of Years Earlier Than Previously Believed

ScienceDaily for March 21, 2008 reported on new dates for the arrival of the early Americans.

A team led by two Texas A&M University anthropologists now believes the first Americans came to this country 1,000 to 2,000 years earlier than the 13,500 years ago previously thought, which could shift historic timelines.

New Zealand's Colonization 1000 Years Later Than Previously Thought?

ScienceDaily for June 4, 2008 reported on new dating of the colonization of New Zealand.

An international team of researchers, led by Dr Janet Wilmshurst from Landcare Research, spent 4 years on the project which shows conclusively that the earliest evidence for human colonisation is about 1280-1300 AD, and no earlier. They based their results on new radiocarbon dating of Pacific rat bones and rat-gnawed seeds. Their results do not support previous radiocarbon dating of Pacific rat bones which implied a much earlier human contact about 200 BC.

Parallel: Migrations to the Americas - Part 6

Previous parts to this post have concerned migrations to the American continents. In this part I discuss the DNA analysis of a migration to Europe and its parallel with the migration of the Lehites to the Americas as described in the Book of Mormon.

As explained in Earliest European Farmers Left Little Genetic Mark On Modern Europe, the first settlers in Europe are believed to have been Paleolithic hunter-gatherers who arrived about 40,000 years ago. About 7,500 years ago people migrated to Europe and brought farming to that area. The question thus arises, are modern Europeans descended from the hunter-gatherers, the farmers, or both?

DNA was obtained from skeletons of early farmers, and the DNA contained "genetic signatures that are extremely rare in modern European populations. Based on this discovery, the researchers conclude that early farmers did not leave much of a genetic mark on modern European populations." In fact, '"Our paper suggests that there is a good possibility that the contribution of early farmers could be close to zero," said Science author Peter Forster from the University of Cambridge in Cambridge, UK.'

The situation given in the Science article is that of two migrations to an area, and the DNA of the later migration not occurring in the people presently living in that area. Since Europe, today, is an agricultural society, the early farmers in the later migration had a significant impact on that area, even though they left basically no genetic evidence of their existence. "It's interesting that a potentially minor migration of people into Central Europe had such a huge cultural impact," said Forster."

This is an interesting parallel with the Book of Mormon. Science tells us of early migrations to the Americas from Asia via the Bering Strait. The Book of Mormon tells of a later migration (the Lehites) from the Mediterranean area. However, DNA studies of modern Native Americans show that the Native Americans who were studied have no DNA markers from the Mediterranean area. Apologists for the Book of Mormon have explained that DNA markers from a group of people could die out and thus not be found in modern people (see, for example, Addressing Questions). We now have from science an example of DNA from a later migration not occurring among modern people currently living in that area.

Ancient Eskimos Came from Asia, Study Says

National Geographic News for May 29, 2008 reported on the origin of ancient Eskimos.

The research is based on DNA analysis of ancient hair from a so-called Paleo-Eskimo, which was found preserved in permafrost soil in the Disco Bay area in the 1980s.

Earliest European Farmers Left Little Genetic Mark On Modern Europe

ScienceDaily for November 13 2005 reported on the DNA of early European farmers.

The farmers who brought agriculture to central Europe about 7,500 years ago did not contribute heavily to the genetic makeup of modern Europeans, according to the first detailed analysis of ancient DNA extracted from skeletons of early European farmers.

New Research Forces U-turn In Population Migration Theory

ScienceDaily for May 26, 2008 reported on new theories about migration into Southeast Asia.

Research led by the University of Leeds has discovered genetic evidence that overturns existing theories about human migration into Island Southeast Asia (covering the Philippines, Indonesia and Malaysian Borneo) - taking the timeline back by nearly 10,000 years.

Tracing Humanity's Path

ScienceNOW for May 23, 2008 reported on a new, DNA based, theory about migrations out of Africa.

The study came up with two unexpected findings. One is that the people of the Orkney Islands, to the north of Scotland, share some ancestry with Siberians, possibly because some ancestors of modern Orcadians ventured to Asia via the Arctic Circle. The team also found that North and South America were colonized independently by at least two different waves of migration from different parts of Asia, although both waves appear to have arrived via the Bering Strait. This conclusion contradicts the conventional view, which postulates just one migratory wave out of Asia.

Did Humans Colonize the World by Boat?

Sub-heading: Research suggests our ancestors traveled the oceans 70,000 years ago.

Discover for May 20, 2008 reported on the theory that early Americans island-hopped as they migrated to the Americas.

Until recently most researchers would have dismissed such talk of Ice Age mariners and coastal migrations. Nobody, after all, has ever unearthed an Ice Age boat or happened upon a single clear depiction of an Ice Age dugout or canoe. Nor have archaeologists found many coastal campsites dating back more than 15,000 years. So most scientists believed that Homo sapiens evolved as terrestrial hunters and gatherers and stubbornly remained so, trekking out of their African homeland by foot and spreading around the world by now-vanished land bridges. Only when the Ice Age ended 12,000 to 13,000 years ago and mammoths and other large prey vanished, archaeologists theorized, did humans systematically take up seashore living—eating shellfish, devising fishing gear, and venturing offshore in small boats.

'Mitochondrial Eve' Research: Humanity Was Genetically Divided For 100,000 Years

NewsDaily for May 16, 2008 reported on recent research about our ancestors in Africa.

The human race was divided into two separate groups within Africa for as much as half of its existence, says a Tel Aviv University mathematician. Climate change, reduction in populations and harsh conditions may have caused and maintained the separation.

After Near Extinction, Humans Split Into Isolated Bands

Pre-Clovis Human DNA Found In 14,300-year-old Feces In Oregon Cave Is Oldest In New World

An article in ScienceDaily reported on human DNA found in Oregon that dates back 14,300 years ago.

DNA from dried human excrement recovered from Oregon's Paisley Caves is the oldest found yet in the New World -- dating to 14,300 years ago, some 1,200 years before Clovis culture -- and provides apparent genetic ties to Siberia or Asia, according to an international team of 13 scientists.

Estimates for peopling of Americas getting earlier

World Science for March 13, 2008 reported on migrations to the Americas.

The mainstream view pre­vail­ing in the past sev­er­al dec­ades holds that hu­mans en­tered the con­ti­nent about 12,000 years ago us­ing a tem­po­rary land bridge from north­east­ern Asia to Alas­ka. These mi­grants would have giv­en rise to a cul­ture of mam­moth hunters known for their un­ique stone pro­ject­ile-points and dubbed Clo­vis, af­ter re­mains found near Clo­vis, N.M., in the 1930s.

But in re­cent years ev­i­dence has turned up that the first Amer­i­cans might have been con­sid­erably old­er, some ar­chae­o­lo­gists ar­gue.

Native American DNA Links to 6 'Founding Mothers'

LiveScience for March 13, 2008 reported that

The six "founding mothers'' apparently did not live in Asia because the DNA signatures they left behind aren't found there, Perego said. They probably lived in Beringia, the now-submerged land bridge that stetched to North America, he said.
