The wild boar (Sus scrofa), also known as the wild swine, [4] common wild pig, [5] Eurasian wild pig, [6] or simply wild pig, [7] is a suid native to much of Eurasia and North Africa, and has been introduced to the Americas and Oceania.
In the words of the biologist Tim Flannery, "ever since the extinction of the megafauna 13,000 years ago, the continent has had a seriously unbalanced fauna". This means, for example, that the managers of national parks in North America have to resort to culling to keep the population of ungulates under control.
A study covering the past 56,000 years indicates that rapid warming events with temperature changes of up to 16 °C (29 °F) had an important impact on the extinction of megafauna. Ancient DNA and radiocarbon data indicates that local genetic populations were replaced by others within the same species or by others within the same genus.
Historically, the Quaternary extinction event was the most dramatic episode of wild mammal decline, as it saw the disappearance of appromixately half of all terrestrial mammal species with a body mass greater than 40 kg. [2] Statistically, this meant a 14% reduction in the average body size of wildlife over the past 125,000 years.
A growing number of scientists believe a sixth mass extinction event of a magnitude equal to the prior five has been unfolding for the past 10,000 years as humans have made their mark around the ...

It was the most severe extinction event of the past 500 million years, wiping out 80% to 90% of species on land and in the sea. Mystery deepens over cause of Earth's worst mass extinction event ...
