Neanderthals, the nearest cousins of present-day people, lived in pieces of Europe and Asia until their elimination exactly a long time back.
Hereditary examinations are uncovering perpetually about the connections between present-day people and these distant memory family members – most as of late that a surge of interbreeding between our species happened in a moderately short eruption of time something like quite a while back. Yet, one secret remains.The Homo sapiens genome today contains a smidgen of Neanderthal DNA. These hereditary follows come from pretty much all aspects of the Neanderthal genome – with the exception of the Y sex chromosome, which is liable for making guys.
So what has been going on with the Neanderthal Y chromosome? It might have been lost unintentionally, or on account of mating examples or second-rate capability. Notwithstanding, the response might lie in exceptionally old hypothesis about the soundness of interspecies mixtures.
