The first four novels form a coherent, more or less linear narrative, from the initial migration of Siberian peoples into what is now Canada and Alaska (People of the Wolf) through the florescence of the Mississippian semi-urban mound-building culture, considered the "high-water mark" of North American pre-Columbian civilization, around 1000 AD.
In zoology, megafauna (from Greek μέγας megas "large" and Neo-Latin fauna "animal life") are large animals. The most common thresholds to be a megafauna are weighing over 46 kilograms (100 lb) [ 2 ] [ 3 ] [ 4 ] (i.e., having a mass comparable to or larger than a human ) or weighing over a tonne , 1,000 kilograms (2,205 lb) [ 2 ] [ 5 ] [ 6 ...
It compares the overkill hypothesis (predator hunting = 0) with second-order predation (predator hunting varied between 0.01 and 0.05 for different runs). The findings are that second-order predation is more consistent with extinction than is overkill [164] [165] (results graph at left). The Pleistocene extinction model is the only test of ...
Depletion of herbivorous megafauna results in increased growth of woody vegetation, [80] and a consequent increase in wildfire frequency. [81] Megafauna may help to suppress the growth of invasive plants. [82] Large herbivores and carnivores can suppress the abundance of smaller animals, resulting in their population increase when megafauna are ...
The first people in Colorado were nomads, following and hunting large mammals using the Clovis point. As Megafauna became extinct, people adapted by hunting smaller animals, gathering wild plants, and cultivating food, such as maize. As the natives became more sedentary, there were significant technological and social advances, including basket ...
A Different Flesh is a collection of alternate history short stories by American writer Harry Turtledove. [1] The stories are set in a world in which Homo erectus, along with various megafauna, survived to the modern times in the Americas as the Native Americans along with any other human cultures.
A marsupial lion skeleton in the Naracoorte Caves, South Australia. The term Australian megafauna refers to the megafauna in Australia [1] during the Pleistocene Epoch.Most of these species became extinct during the latter half of the Pleistocene, and the roles of human and climatic factors in their extinction are contested.
An important difference between Europe and other parts of the inhabited world was the northern latitude. Archaeological evidence suggests humans, whether Neanderthal or Cro-Magnon, reached sites in Arctic Russia by 40,000 years ago. [91] Cro-Magnon are considered the first anatomically modern humans in Europe.
