FOXP2 Gene

Neanderthals and modern humans have same version of the FOXP2 gene.
The present version of the gene located on the 7th chromosom, evolved about 200,000 years ago and is believed to be connected with speech.

The same gene is linked with song in birds.

Firms doing genetic genealogy

These firms tell you your mitochonrial and Paternal Haplotype ancestry.
You might be Haplotype X on the maternal side and R1A1 on the paternal side.

Human evolution speeded up 40,000 years ago.

Researchers from the University of Wisconsin analysed 3.9 million genetic differences called SNPs( single nucletide molypormism from 270 people, information gathered by the International Hapmap project.

These 270 people were North European, Chinese, Japanese and Nigerian.

About 7% or 1800 genes have changed during the last 40,000 years because of natural selection.

Human rates of evolution must have speeded up, especially during the last 4/5,000 years.

Humans have evolved resistance to diseases like malaria, as well as traits like lactose tolerance.

It was previously thought that humans reached their present form around palaeolithic times.

Natural selection may also be favouring teenage pregnancies

Genographic Project

This project connected with Nattional Geographic is trying to trace humanity's journey throughout the world by genetics.

Has atlas of the human journey, it has haplotypes and haplogroups, both male and female.

Tests reveal Liverpool's Viking origins

A genetic study of men in Liverpool focusing only on men whose surnames were in the Liverpool area before the Industrial Age revealed 50% had Norse ancestry
The researchers used historical documents to find out which surnames were there before the Industrial Age.
The male haplotype R1a was found, it is common in Norway.
