The abrupt extinction of the megafauna during the Pleistocene in North America dwindled the large animal population to about 70 percent (Martin). The cause of this massive extinction is unclear due to lack of evidence during this time‚ but there are many subjective beliefs that involve both ecological and environmental forces. An ecological force such as human hunters are one hypothesis that is believed to have caused the extinction of the megafauna. This hypothesis is known as the “overkill hypothesis

bees have on this world. Although they may sting people‚ their task is vital to agriculture. Bees pollinate flowers‚ crops‚ and plants. Without bees‚ a majority of the crops around the world would be destroyed. Just a simple dinner would be hard to enjoy- there would be no honey for the bread.

In fact‚ the deforestation and environment pollution have put creatures on the verge of extinction. Domestic apes in Vietnam‚ which have die out due to shrinking of tropical trees‚ could be taken as a particularly salient example of this. Ignoring the impact of human on minimizing the habitat of animals is thereby a grave mistake. Additionally

Utilizing the extensive fossil record at hand for Ceratopsians and Pachycephalosaurs they microscopically examined the bones looking for levels of bone maturity and metaplastic bone to discern the animals place in the growth series and develop their hypothesis for stages of growth for these dinosaurs.

Details about the nature of this evolution are still debated‚ but the general idea can be explained in a four-stage hypothesis. In this four-stage hypothesis‚ the first stage was the abiotic formation of organic molecules‚ such as amino acids and nucleotide monomers. The idea that organic molecules can be formed abiotically

1.) Were the North American megafauna wiped out by early human colonizers? The Overkill hypothesis is of the Clovis crossing into a “virgin continent” (The America’s) and wiped out the megafauna due to overhunting. First developed by Paul Martin in the 1960’s‚ Clovis started to occupy North and South America 13‚500-12‚500 years ago; soon after early sites were established 17 genera of North and South American megafauna went extinct between 13‚250-12‚900 (other species such as ground sloths become
