What would the Earth be like if humans never existed

Around 4 millions year ago, the ancestors of humans and chimpanzees diverged, genetic evidence suggests. What, if Chimpanzee–human last common ancestor(1) would suddenly die before giving birth to any babies? What would the Earth be like if humans never existed?

Researchers from Aarhus University in Denmark demonstrated that the Earth without humans would resemble Serengeti(2), a geographical region in Africa which hosts the largest terrestrial mammal migration in the world.

Water found on the exoplanet 51 Pegasi b

Scientists spotted water in the atmosphere of 51 Pegasi b, one of the first exoplanets ever been discovered. It is around 50 light years away – so we can call it a “nearby” exoplanet – and it is in the constellation of Pegasus.

51 Pegasi b has not marked a breakthrough in astronomical research for the first time: back in 1995, it was the first exoplanet to be discovered orbiting a main-sequence star. The first confirmed exoplanet discovery came in 1992 when several terrestrial-mass planets orbiting the pulsar PSR B1257+12.

How the darkness and the cold killed the (non-avian) dinosaurs

Now we have a computer simulation of how the afterward effects of famous Chicxulub asteroid (estimated to be 10 km/6.2 mi) wide) killed the non-avian dinosaurs (and also a wide range of other species). On January 13, 2017, an article titled “Baby, it’s cold outside: Climate model simulations of the effects of the asteroid impact at the end of the Cretaceous”, published by the Climate scientists of Potsdam Institute for Climate Impact Research (PIK), revealed a detailed model of what happened to the atmosphere and the climate after the Chicxulub impact.

Monkeys Accidentally Kill A Robot Baby Monkey And Then Mourn For It – Amazing Video

Do animals understand death? Do they grieve and mourn for their loss? Do they feel empathy for those who suffer? Yes, is the answer to all these questions.

If you “know” animals you already know this too. And there are many scientific studies that conclude animals can understand death and grieve for their losses. Scientists have known for years that big-brained mammals (i.e. gorillas, chimpanzees etc.) may grieve when a family member or close friend, or even a pet dies. But, now, we know that mourning is found more widely in animals than once science has recognized: it extends to horses, cats, dogs, rabbits, birds, and many more.

Two stars may collide and light up night sky in 2022

Two stars may collide into a stunning “red nova” in 2022 (or a few months earlier, most probably between September 2021 and September 2022), and for a few weeks become one of the brightest objects in Earth’s night sky, scientists predict. When two stars merge, they increase in brightness 10 thousandfold.

What would happen if humans became extinct?

In the last few thousand years, humans have had a powerful impact on Earth. Within a geological blink of an eye, we exploded out of Africa to colonize virtually every inhabitable space on the planet. We dammed the rivers, we domesticated animals, deforested many areas, changed the chemistry of the atmosphere and the seas… the list goes on. But, what would happen if humans suddenly become extinct in the future?

One may think “humans are so intelligent, so it’s very unlikely that the entire human race will be gone”. But, in fact, there is a strong chance that it will happen, and probably not in the long run!

10 Recently Lost Natural Wonders

The Earth is always changing. “The only thing that is constant is change, as Heraclitus (c. 535 – c. 475 BC) the pre-Socratic Greek philosopher once said. Unfortunately, things do not always happen the way we would have wanted. Here are 10 recently lost natural wonders that have been disappeared in recent centuries or even decades.

The Sixth Major Extinction Event

In the past, there were five major extinction event (a widespread and rapid decrease in the biodiversity on Earth), and a lot of minor ones. Now, we are in the middle of the sixth one, called “Holocene extinction event”. And the cause is… guess what? Humans.

According to the WWF’s (World Wildlife Fund) new Living Planet Report (2016), now we are in the middle of the biggest mass extinction on Earth, since the dinosaurs, which was around 65 million years ago. And the world set to lose two-thirds of its wildlife by as close as 2020.
