I propose a new scenario for the discovery of America. By analogy with other successful animal invasions, one may assume that the discovery of the New World triggered a human population explosion. The invading hunters attained their highest population density along a front that swept from Canada to the Gulf of Mexico in 350 years, and on to the tip of South America in roughly 1000 years. A sharp drop in human population soon followed as major prey animals declined to extinction. Possible values… Expand
The Initial Colonization of North America: Sea Level Change, Shoreline Movement, and Great Migrations
A number of different scenarios have been proposed regarding the origin, timing, and directions initial populations took as they first entered the Americas. In this chapter the major colonizationExpand
Extinctions in North America's Late Glacial landscapes
Human-caused extinctions of terrestrial mammals in large parts of the world such as North America may have been side-effects of rapid long-distance dispersals (biogeographic range-change) by HomoExpand
The timing and effect of the earliest human arrivals in North America
TLDR
A Bayesian age model suggests that human dispersal to the Americas probably began before the Last Glacial Maximum, overlapping with the last dates of appearance for several faunal genera and was a key factor in the extinction of large terrestrial mammals. Expand
Late Quaternary Extinctions: State of the Debate
Between fifty and ten thousand years ago, most large mammals became extinct everywhere except Africa. Slow-breeding animals also were hard hit, regardless of size. This unusual extinction of largeExpand
An analysis of the chronology of late Pleistocene mammalian extinctions in North America
Abstract Some 35 genera of mammals became extinct in North America as the Pleistocene came to an end. Current attempts to explain those extinctions generally assume that all of the losses took placeExpand
Late Pleistocene mammalian extinctions in North America: Taxonomy, chronology, and explanations
Toward the end of the Pleistocene, North America lost some 35 genera of mammals. It has long been assumed that all or virtually all of the extinctions occurred between 12,000 and 10,000 years ago,Expand

Publisher Summary This chapter describes peopling in North America and summarizes where they were when The International Union for Quaternary Science (INQUA) was here in 1965. One element common toExpand
A requiem for North American overkill
The argument that human hunters were responsible for the extinction of a wide variety of large Pleistocene mammals emerged in western Europe during the 1860s, alongside the recognition that peopleExpand

TLDR
A comparative study of mammalian sperm showed common structure but species differences in the thickness of the outer fibers length of the midpiece and overall diameter of the tail, consistent with the interpretation that the axoneme is capable of functioning independently of a mitochondrial energy source but that the long middle piece of vertebrate sperm has evolved to meet the energy requirements of the accessory outer fibers.
