But how long can humans last? Eventually humans will go extinct. At the most wildly optimistic estimate, our species will last perhaps another billion years but end when the expanding envelope of the sun swells outward and heats the planet to a Venus-like state. But a billion years is a long time.
Will humans survive? Yes, almost certainly, but the factors that determine the outcome are so immensely complex that our blunt and instrumental efforts are almost meaningless. The only thing that makes a difference is the combined impact of all individual animals including humans.
In the next 1,000 years, the amount of languages spoken on the planet are set to seriously diminish, and all that extra heat and UV radiation could see darker skin become an evolutionary advantage. And we're all set to get a whole lot taller and thinner, if we want to survive, that is.
How Human Beings Almost Vanished From Earth In 70,000 B.C. : Krulwich Wonders... By some counts of human history, the number of humans on Earth may have skidded so sharply that we were down to just 1,000 reproductive adults. And a supervolcano might have been to blame.
Human extinction is the hypothetical end of the human species due to either natural causes such as population decline from sub-replacement fertility, an asteroid impact, large-scale volcanism, or via anthropogenic destruction (self-extinction).
Earth is likely to cross a critical threshold for global warming within the next decade, and nations will need to make an immediate and drastic shift away from fossil fuels to prevent the planet from overheating dangerously beyond that level, according to a major new report released on Monday.
Humans in the year 3000 will have a larger skull but, at the same time, a very small brain. "It's possible that we will develop thicker skulls, but if a scientific theory is to be believed, technology can also change the size of our brains," they write.
"[W]e must … continue to go into space for the future of humanity," Hawking said in a lecture at the University of Cambridge this week. "I don't think we will survive another 1,000 years without escaping beyond our fragile planet."
There were once nine human species, now it's just us. But could new human species evolve? For that to happen, we'd need isolated populations subject to distinct selective pressures. Distance no longer isolates us, but reproductive isolation could theoretically be achieved by selective mating.
More reproduction followed, and more mistakes, the process repeating over billions of generations. Finally, Homo sapiens appeared. But we aren't the end of that story. Evolution won't stop with us, and we might even be evolving faster than ever.
According to a US report, the sea level will increase by 2050. Due to which many cities and islands situated on the shores of the sea will get absorbed in the water. By 2050, 50% of jobs will also be lost because robots will be doing most of the work at that time. Let us tell you that 2050 will be a challenge to death.
Temperatures will be dangerously hot in more places and at more times than ever before. Less of Earth will be as agreeably habitable as in the past. Ecosystems and our relationships with ecosystems will continue to change, creating even more insecurity on the planet.
Broadly speaking, evolution simply means the gradual change in the genetics of a population over time. From that standpoint, human beings are constantly evolving and will continue to do so long as we continue to successfully reproduce.
Some parts of the world will be uninhabitable by 2050 due to climate change, according to NASA. NASA recently published a map of the world showing the regions that will become uninhabitable for humans by 2050.
Humans can't live forever, but we haven't even come close to the limit for how long our bodies could last. Researchers estimate that the human body may not be capable of living more than 150 years.
Of you being here? Author and blogger Dr. Ali Binazir did the calculations last spring and decided that the chances of anyone existing are one in 102,685,000. In other words, as this infographic figures it, you are totally improbable.
"Those creatures have been on their own lineage for 10 million years. You can't go back up that lineage and back down again." Even if chimpanzees could suddenly develop the traits of an Australopithecus, they probably wouldn't want to.
The great apes – chimps, gorillas, orangutans and bonobos – are smart. Real smart. They can be taught to communicate via sign language. They have social hierarchies complex enough to rival our own.
No animal will develop human-like intelligence if its circumstances don't become similar to those that required our ancestors to develop bigger brains.
Based on known risks, the really cataclysmic ones, those that might exterminate us as a species, are fairly rare. Based on what we know today, it would be very unlikely that we wouldn't be around in the year 3000.
There are three times in history during which humans nearly went extinct. Here's what threatened us, and how we survived.
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.
So what's going to happen in 2045? It's pretty likely that robots and artificial technology will transform a bunch of industries, drone aircraft will continue their leap from the military to the civilian market, and self-driving cars will make your commute a lot more bearable.

In 100 years, the world's population will probably be around 10 – 12 billion people, the rainforests will be largely cleared and the world would not be or look peaceful. We would have a shortage of resources such as water, food and habitation which would lead to conflicts and wars.
