DNA Search for First Americans…

Luzia

More evidence that contradicts the theory that prehistoric native peoples came to the Americas in a single wave.  This new DNA study of Amazonian peoples indicates they are related to Australian aboriginal peoples and New Guineans, and while the DNA evidence is new, this is not a new hypothesis.  Archaeologists studying the remains of Luzia and her people in Brazil (which dates to over 12,000 B.P.) have long said that the physical characteristics of Luzia most closely match those of Australoids or Africans.   The new study suggests there were at least two very early migrations into the Americas, but hang onto your hats, folks.  We suspect when the dust finally settles, the genetics will suggest many more migrations.

Genetics. 17% of what we think we know about disease genes is wrong…

For those of you who have decided to have genetic testing done to determine your likelihood of certain diseases, please read this article.  The study of genetics is amazing, but the truth is that no one really knows what most of those genes do.  There are still way too many ‘holes in our knowledge’ that need to be filled in.
