Quotes About Interbreeding

For our purposes, if we are to look at the evolution that led to where we are now, instead of the nice neat tree, I think it could reasonably be described as one big million-year clusterfuck. Whenever humans met - Sapiens, Neanderthal, Denisovans - they had sex. What a time to be alive.

The question of our relationship with Neanderthals has been refined with genetics, in terms of our shared ancestors; our lineage moved away from theirs around half a million years ago. But what DNA analysis revealed more categorically than anything else was that we had sex with them, repeatedly, probably as soon as these two peoples met, and every time afterward.

crunching. The amount of introgression from Neanderthals is proportionally lower on the modern X than on the rest of the chromosomes. X chromosomes are only passed on by males half of the time because we also have a Y, but all of the time by women, who have two Xs. The observation that there is less Neanderthal DNA on our Xs implies that the first encounters we had with them that resulted in procreation were male Neanderthals with female Homo sapiens.

Race theorists, who are as old as imperialism itself, want to achieve racial purity in peoples whose interbreeding, as a result of the expansion of world economy, is so far advanced that racial purity can have meaning only to a numbskull.

The families in positions of great financial power obsessively interbreed with each other. But I'm not talking about one Earth race, Jewish or non-Jewish. I'm talking about a genetic network that operates through all races, this bloodline being a fusion of human and reptilian genes.

A further feature that distinguished the experiences of South and North America was the absence of a racialist prohibition on intermarriage and interbreeding, which prevailed particularly in the slave states of the southern British colonies. In part this was because very few white women travelled across from Spain to Latin America; and in part because the Spanish did not suffer from the same type of racism and puritanism as northern European Protestantism.

Where it concerns human beings, it is almost always true that the more anxiously we look for purity the more likely we are to come upon admixture and interbreeding.

the two evolutionary lines, ours and the Neanderthals', both developed such large brains, and perhaps other characteristics in common, because we exchanged genes.

You look at the modern humans that a lot of us have slept with and it is hardly a surprise if a Neanderthal maiden or two might have twinkled by the campfire light.

I don't know why scientists have been so resistant to the idea of interbreeding. You look at the modern humans that a lot of us have slept with and it is hardly a surprise if a Neanderthal maiden or two might have twinkled by the campfire light.

Admittedly there could have been interbreeding between archaic and modern Homo sapiens, but there is no convincing evidence for this in our male and female gene lines. So

I don't think we interbred with the Neanderthals at all. There are some people who think that there was some level of interbreeding. I think that we look so biologically different, that we looked and we acted so different, and we culturally were so different that we would not have had interbreeding between two species.

Some pundits have proposed that the aliens have come here to breed with us. Apparently, too much bike riding or something similar has rendered them incapable of reproducing within their own species. But do extraterrestrial infants toddle through your neighborhood?

It is with the [head louse and body louse] that we are chiefly concerned, and they are so closely related that, even now, by an occasional mésalliance resulting from the meetings of young people about the neck band, a body louse may go native and interbreed with a head louse. The crab louse we may neglect. He is probably of distinct generic origin and a creature that merits neither respect nor sympathy; not even terror.

If populations can interbreed with each other in their natural habitat, they belong to the same species. Of course, with fossil animals, that's not possible—if we wait for two fossils to interbreed, we'll be waiting a very long time.

As a result, man is the only successful type which has remained as a single interbreeding group or species, and has not radiated out into a number of biologically separated assemblages
