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.

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.

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.

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!
An alligator’s brain weighs only 8 or 9 grams, and it has the size of a walnut, but that doesn’t mean they are stupid. In fact, they’re much smarter than you’d think. In Everglades National Park in the United States, a 400-pound (181 kg) gator displays a clever way and uses a bait branch stick to catch egrets during the breeding season.

Like crocodiles, snakes also suffer from a prevalence of “big fish” stories and over-exaggeration in the internet era. In fact, it is very difficult to measure how large actually a snake is, especially if it’s really big. So, how big are the largest snakes actually?

If you search for the fastest land animals on the Internet, you will find many “fastest animals” lists, most of them are popular “top list” sites. But, in fact, there is a tendency to overestimate the speed of fast animals. Even the speed of the world’s fastest land animal, cheetah’s speed is usually highly overestimated.
Measuring an animal’s speed is a very hard task, and very few of them were properly authenticated. Some of them are really fast, that’s true, but what is the exact number? This information is usually not measured correctly.

The Okavango Delta is a unique pulsing wetland where the 1,600 km (990 mi) long Okavango River reaches a tectonic trough in the middle of the Kalahari Desert in northern Botswana. Each year approximately 11 cubic kilometers of water spread over the 6,000-15,000 km2 area. It is on the UNESCO World Heritage List as well as one of the Seven Natural Wonders of Africa. (1)
