在傳統的美洲人類殖民觀點中,來自亞洲的大型獵物獵人——所謂的克洛維斯人——大約在13000年前迅速穿越了一個現在淹沒的名為白令陸橋的陸地進入北美,並迅速向南進入溫暖的氣候。然而,在過去的十年中,反對這種“克洛維斯優先”情景的證據越來越多,正如11月刊中的這篇文章所述。最新的地質和考古研究表明,人類在克洛維斯人留下他們獨特的石器之前數千年就進入了新世界,並提出了兩條可能的遷徙路線:一條沿海路線和一條早期的無冰走廊。

Kate Wong is an award-winning science writer and senior editor at 大眾科學 focused on evolution, ecology, anthropology, archaeology, paleontology and animal behavior. She is fascinated by human origins, which she has covered for more than 25 years. Recently she has become obsessed with birds. Her reporting has taken her to caves in France and Croatia that Neandertals once called home, to the shores of Kenya's Lake Turkana in search of the oldest stone tools in the world, to Madagascar on an expedition to unearth ancient mammals and dinosaurs, to the icy waters of Antarctica, where humpback whales feast on krill, and on a "Big Day" race around the state of Connecticut to find as many bird species as possible in 24 hours. Kate is co-author, with Donald Johanson, of Lucy's Legacy: The Quest for Human Origins. She holds a bachelor of science degree in biological anthropology and zoology from the University of Michigan.
