Africans Have Stronger Immune Systems Than Europeans – Thanks To Neanderthals

0
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.
