Quoted By:

Some Neanderthal genes are thought to be marginally harmful due to their extreme historic bottleneck prior to mating with humans and superior genes will gradually reduce them
other parts could be n environment that selects against they're climatic and lifestyle adaptations. should humans be reduced to living under those primitive conditions again there might be a reversal

I really wish you had a citation, because that would be an interesting paper to read.

they're also the source of high altitude oxygen afdfinity genes associated with tibet
there are a whole bunch of genes they contributed to improve survival but massive purged regions of the genome like neural structure or immune system
