Thorne emphatically (and I believe sincerely) dismisses the idea that his theory is in any measure racist and accounts for the uniformity of human evolution by suggesting that there was a lot of movement back and forth between cultures and regions. "There's no reason to suppose that people only went in one direction," he says. "People were moving all over the place, and where they met they almost certainly shared genetic material through interbreeding. New arrivals didn't replace the indigenous populations, they joined them. They became them." He likens the situation to when explorers like Cook or Magellan encountered remote peoples for the first time. "They weren't meetings of different species, but of the same species with some physical differences."

卡爾頓·庫恩堅決(這一點我確信無疑)否認他的理論有任何種族主義傾向。他認為,存在于不同的文化和地區之間的反反復復的交流,說明了人類進化的同源性。沒有理由認定人類只沿著一個方向進化,” 他說,“人類在世界各地流動,幾乎可以肯定,在交匯的地方,通過異種交配,分享了基因。新來的人并沒有代替土著居民,而是融入到他們中間,最后變成一體。” 他打了一個比喻,當庫克和麥哲倫這樣的探險家第一次遇到偏遠地區的居民時,“他們并沒有遇到不同的種族,而只是遇到了某些身體特點有所不同的同類”。

What you actually see in the fossil record, Thorne insists, is a smooth, continuous transition. "There's a famous skull from Petralona in Greece, dating from about 300,000 years ago, that has been a matter of contention among traditionalists because it seems in some ways Homo erectus but in other ways Homo sapiens. Well, what we say is that this is just what you would expect to find in species that were evolving rather than being displaced."

桑恩堅持認為,在人類化石上你所能觀察到的也是一個均衡而不斷的變遷。有一副發現于希臘佩特拉朗納的很著名的骸骨,大約生活于30萬年前,就是一件在傳統主義者中間一直富有爭議的事,因為他似乎同時具有直立人和智人的某些特征。怎么說呢?我們要說的是,這正是你會期望在物種身上看到的:他們是在進化,不是在替代。”
