The arrival of human, and not climate change, is most likely the primary cause of the sharp dive in the population of the Australian Megafauna some 45,000 years ago.
Over half of the non-human primate species are facing extinction in the next 50 years, and humans are to blame.
The long incubation period of dinosaurs could be part of the reason these species could not compete with more prolific animals millions of years ago.
Global cheetah population has dropped with just 7,100 left.
World's fastest land animal is sprinting its way to extinction, with only 7,100 individuals globally.
Recent scientific studies have shown that the Earth is slowly dying due to the amount of pollution and the over population. However, a NASA scientist has sent out a warning claiming that the extinction of the earth is soon due - and despite efforts to stop it, it will come. The cause of Earth’s extinction is said to be a comet or asteroid strike.
The asteroid that allegedly hit the Earth and killed all dinosaurs did not actually wipe out all life on Earth. In fact, it may have been one of the reasons why life was restored. There had been reports that life re-emerged exactly where the asteroid hit Earth.
NASA says a comet strike on Earth could be more catastrophic and damaging than an asteroid strike.
Giraffes are now at risk of extinction as their numbers reportedly dropped by 40 percent in the last 30 years. With all the attention on global warming and climate change, many were surprised to find giraffes slowly disappearing. Scientists believe that if their population declines further, giraffes will be vulnerable to extinction.
The powerful asteroid that wiped off the dinosaurs on Earth 66 millions years ago caused the planet's surface to vaporize and act like a liquid, a new study reveals.
The last known living member of a rare tree frog species in captivity, the Rabb's fringe-limbed tree frog, has died despite the Atlanta Botanical Garden's best efforts to save it.
Six species of native Hawaiian honeycreepers could be extinct within the next 10 years due to climate change and rat infestation.
Did you know that the Grauer's gorilla is the largest of the gorilla subspecies and shares 98.3 percent of their DNA with humans?
