Mammals, birds and amphibians are currently becoming extinct at rates comparable to the previous five mass extinctions.
In the past four decades, half of the world's species are either going endangered or going extinct. Even familiar animals like giraffes are now endangered, and certain species of rhinos in Africa are about to be extinct. The world, in its entirety, is going ballistic. The worst part of it all is that humans are among those that are in danger.
After the five previous mass extinctions faced by planet Earth, the sixth may happen by 2020 according to the projections made by WWF and the Zoological Society of London. Given the current rate of biodiversity loss, including climate change, what we are facing is a problematic future with no assurance of our system's stability which is one of the milestones caused by this era on man: the Anthropocene.
A team of scientists has identified the first-ever evidence of a comet colliding with planet Earth about 56 millions of years ago, suggesting that the catastrophic event could have lead to an abrupt warming period or Paleocene-Eocene Thermal Maximum (PETM) on Earth.
Gamma ray bursts and supernovae often occur outside the Earth's galaxy, but is it possible for these distant events to cause destruction in the planet - maybe even cause mass extinction? Scientists take a closer look.
NASA to send a spacecraft to Bennu to study the 4.5 billion years old asteroid and collect sample to bring back on Earth.
New fossil evidence show that the rise of ecological engineers during the cambrian explosion may have change the ecological aspects of Earth causing the first mass extinction.
A new study suggests that iron-rich, low-oxygen ocean is the most likely cause of the delayed recovery of the Earth after the mass extinction event 252 million years ago.
A new study of more than 6,000 marine fossils from Antarctica reveals that the mass extinction event, which killed dinosaurs, was sudden and just as deadly to life in the polar regions.
Scientists have discovered a fossil of a new ancient marine animal that resembles present-day dolphins. The said fossil gives a hint of how marine reptiles survived mass extinction 250 million years ago.
Fossils unearthed from the Sahara Desert in Tunisia reveal the largest-known ocean-dwelling member of the crocodile family tree. This prehistoric predator dates back 130 million years, changing the way scientists view the mass extinction that is thought to have occurred at the end of the Jurassic period, 145 million years ago.
Following the mass extinction of dinosaurs, mammals were able to rapidly diversify and radiate without the threat of predation.
Small fish dominated oceans following a mass extinction 359 million years ago. This suggests small fish actually have an evolutionary advantage over larger marine predators.
New evidence suggests that periodic mass extinctions occurring over the past 260 million years are directly linked to comet or asteroid showers.
