A little light lunchtime reading, confirms that there is always something new in the world of science.
This is because the science fact of yesterday, which replaced the science fact of the day before, is now jettisoned in favor of the science fact of today.
So, Whoooo are You …
From the BBC:
“A new study deals a blow to the idea that most European men are descended from farmers who migrated from the Near East 5,000-10,000 years ago.
The findings challenge previous research showing that the genetic signature of the farmers displaced that of Europe’s indigenous hunters. …The extent to which modern Europeans are descended from these early farmers versus the indigenous hunter-gatherers who settled the continent thousands of years previously is a matter of heated debate.
The results vary depending on the genetic markers studied and are subject to differing interpretations.
The latest study focused on the Y chromosome – a package of DNA which is passed down more or less unchanged from father to son.
The Y chromosomes carried by people today can be classified into different types, or lineages, which – to some extent – reflect their geographical origins.
More than 100 million European men carry a type called R-M269, so identifying when this genetic group spread out is vital to understanding the peopling of Europe.”
“R-M269 is most common in western Europe, reaching frequencies of 90% or more in Spain, Ireland and Wales.
The latest research leans towards the idea that most of Europe’s males trace a line of descent to stone-age hunters.
But the authors say more work is needed to answer this question. …”
The matter above of course is widely recognized as an unsettled issue (no pun intended). Other questions of origins and development however, have generally been considered as more or less put to rest.
However, if the assertions contained in the following link are correct, all you horse fanciers may find your accepted narrative subject to a rather radical revision too.
Just in case there are any city dwelling youth who might stumble across this blog and be uncertain regarding the concept of a horse, from Wiki:
