AFRICANGLOBE - The immune systems of Europeans were partly shaped by the introduction of new genetic variants through interbreeding between early European ancestors and Neanderthals. Strong evidence of selection on genes that control the immune response and that Europeans 'borrowed' some key regulatory variants from Neanderthals. These variants affect the way their immune systems respond to viral challenges, giving them a lower response to infection than those of African descent. One study suggests Americans of African descent have a stronger immune response to infection compared to Americans of European descent.
AFRICANGLOBE - A new study published in the journal Naturehas found that Neanderthals lived alongside humans for many centuries, and that they may have died out in the 2,000 years between 41,000 and 39,000 years ago in what is now modern-day Belgium.
AFRICANGLOBE - Two recent studies have shown that non-Africans have a significant number of Neanderthal genes lurking in their DNA, influencing their skin and hair, their response to certain diseases and even their smoking behaviour.
AFRICANGLOBE - If your heritage is non-African, you are part Neanderthal, according to a new study in the July issue of Molecular Biology and Evolution. Discovery News has been reporting on human/Neanderthal interbreeding for some time now, so this latest research confirms earlier findings.
AFRICANGLOBE - Neanderthals lost out to Homo sapiens in the battle to survive because they were not clever enough to adapt. Europe was once dominated by Neanderthals, but they disappeared after modern man from Africa was thought to have emerged 60,000 years ago
