Megafauna

reframing the theory of human migration out of Africa. The article addresses such areas as archaic hominins and their interbreeding with AMHs (anatomically modern humans), the path and timing of human migration through Eurasia and the Americas, and Megafauna extinction. All of these topics benefit from new insights and theories due to the role of aDNA analysis. The first area addressed by the article, is the new clarity brought to the human migration out of Africa. It has been a long accepted…

Wales, Australia. For the past 120,000 years, sediments from the lake kept building up, forming the “Walls of China”. But also, during those years, erosion from the rain worked its way against the rock, revealing ancient objects such as fossils, megafauna, and clay balls. In 1969, Jim Bowler discovered a skeleton sticking out of the ground, later named Mungo Woman, then a couple years later in 1974, he found another skeleton, now known as Mungo Man. Also, along with these discoveries,…

It is likely that the northern inhabitants could exploit the megafauna of the "Mammoth Steppe" while the southern populaces needed to sit tight for hotter and more steady atmospheres before they could get to more abundant food resources , to bolster their populace expansion. Haplogroup O was found at a high recurrence…

greater-than-we-thought-64063 Researchers found that 60% of the world’s largest herbivores, and 59% of the world's largest carnivores are facing large population and range loss. Earth’s megafauna, large animals, are becoming more and more endangered all over the globe. The places that home the most megafauna are Africa, North America, Northern Europe and parts of Asia. The highest densities of these animals are in parts of Southern and East Africa. Humans are the biggest threat to these…

Evan Johnson August 16, 2017 AP Environmental Science Period 5 Summer Assignment 1. A Panamanian town known as El Valle de Anton, used to have an abundance of a species called the golden frog. Then, when humans began migrating from region to region, the spread of a fungus called Chytrid began to take shape. As the fungus spread, the amphibian population began to dwindle. El Valle de Anton is important because it shows how a mass extinction can occur from the spread of a fungus, all because of…

The Smithsonian writer Guy Gugliotta in his article ‘When did humans come to America?’ explains that the peopling of the Americas, happened sometime in the past 25,000 years where due to a wave of big game hunters crossed into the New World from Siberia at the end of the last ice age, when the Bering Strait was a land bridge that had emerged after glaciers and continental ice sheets froze enough of the world’s water to lower sea level as much as 400 feet below what it is today. Ted Goebel from…

The sabre-toothed tiger is a well-known prehistoric animal along with the woolly mammoth. Sabre-toothed tigers were said to have roamed the mid-western US and parts of both North and South America.They were named for their enormous canines that protruded quite far out of their mouths. This animal became extinct during the end of the dinosaur period. But the main question people inquire, is “How did this animal go extinct?” Due to the fact that there might not have been many of these tigers,…

mammal’s amphibian and birds signifying that high extinction rates in the past was more prevalent in more climatically unstable regions. In a report done by Stephen Wroe and his team which studied how Climatic changes influenced the extinction of megafauna he documents how they “used mean annual temperature and annual precipitation anomaly and velocity between the past and the present to represent the…

The anthropologist Jared Diamond uses the theory of geographic determinism to answer why some societies are more materially successful than others, in his book. According to him geographical causes are mainly responsible for societal development and responsible for different human civilizations developed in different ways. He provides evidence and reasoning that geography, immunity to germs, food production, the domestication of animals, and use of steel are main drivers for societal success.…
