Doughty hypothesizes that without humans, elements would be more evenly distributed across the landscape. This would mean more fertile soil, which would cause ecosystems to be more productive. "If the elements are more patchy in ecosystems, the productivity is going to be more patchy," Doughty said.
What if there were no humans on Earth?
Lacking human oversight, glitches in oil refineries and nuclear plants could lead to fires, nuclear explosions and fallout. Earth would flourish. It appears the vast over population and pollution of the world is the result of over thirty millennia of struggle to reach the Moon...

What species would become dominant if humans died out?

When humans are gone, other species may take our place, but bacteria will continue to dominate the planet.
What was the color of the first humans?

Can humans be wiped out?
The scientific consensus is that there is a relatively low risk of near-term human extinction due to natural causes. The likelihood of human extinction through its own activities, however, is a current area of research and debate.
Will the dinosaurs come back?
This may seem like the most far-fetched concept ever, but believe it or not, it has been predicted that humans will be able to bring dinosaurs back from extinction in some capacity by 2050.

What if humans had wings?
What if we did have wings though? Even if humans did have wings, we wouldn't immediately be able to fly. To fly, we would also need the right body size and metabolism. Metabolism is our body's ability to use fuel (such as from the food we eat) to make energy, which helps us move.
What would Earth look like without an atmosphere?
The Earth's sky would look like that. All unprotected plant and animal life on the Earth's surface would die. We can't survive long in a vacuum, which is what we'd have if the atmosphere suddenly vanished. It would be much like being "spaced' or shot out of an airlock, except the initial temperature would be higher.
How many years does the earth have left?
By that point, all life on Earth will be extinct. Finally, the most probable fate of the planet is absorption by the Sun in about 7.5 billion years, after the star has entered the red giant phase and expanded beyond the planet's current orbit.
What if humans had tails?
It would be similar to having a finger broken. Tails would be sexualized. Tail length and girth would become a major factor in how males were perceived and “tail envy” would be ubiquitous. There would be fierce, violent debate over whether it is proper for females to expose their tails in public.
What will humans look like in 100000 years?
100,000 Years From Today
We will also have larger nostrils, to make breathing easier in new environments that may not be on earth. Denser hair helps to prevent heat loss from their even larger heads. Our ability to control human biology means that the man and woman of the future will have perfectly symmetrical faces.

What skin color is most common?

Where did humans come from in the beginning?
Humans first evolved in Africa, and much of human evolution occurred on that continent. The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa. Most scientists currently recognize some 15 to 20 different species of early humans.

No animal will develop human-like intelligence if its circumstances don't become similar to those that required our ancestors to develop bigger brains.
Why are humans so smart?
Humans have been widely acknowledged as the most intelligent species on the planet; we have big brains with ample cognitive abilities and processing power which outcompete all other species. In fact, humans have shown an enormous increase in brain size and intelligence over millions of years of evolution.
