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.
By the year 3000, global warming would be more than a hot topic — the West Antarctic ice sheet could collapse, and global sea levels would rise by about 13 feet (4 meters), according to a new study.
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 certainly would be bad times, but some of us would get through it. That leaves unknown risks.
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.
While, as shown with creatures such as hydra and Planarian worms, it is indeed possible for a creature to be biologically immortal, these are animals which are physiologically very different from humans, and it is not known if something comparable will ever be possible for humans.
In theory, yes—but it would take millions of years and involve several evolutionary steps before we could even begin to think about flying. Therefore, it is safe to say that humans will not be able to evolve wings through natural selection anytime soon.
In 10,000 years, if we totally let it rip, the planet could ultimately be an astonishing 7 degrees Celsius warmer on average and feature seas 52 meters (170 feet) higher than they are now, the paper suggests.
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.
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.
Heatwaves will be more frequent and long-lasting, causing droughts, global food shortages, migration, and increased spread of infectious diseases. Moreover, as the polar ice will melt, sea levels will rise substantially, affecting a large number of coastline cities and as many as 275 million of their inhabitants.
In a future with “moderate-high” greenhouse emissions and few efforts to mitigate these gasses, our world is truly transformed. First, there is an increase in heat. In this model (RCP 6.0), the world will be 2.2 degrees C higher in 2100 than today. And by 2500, the world will be a full 4.6 degrees C higher.
It is expected that by 2070 life expectancy at birth will increase to 89.8 years for women and 87.7 years for men – an increase of about 5 and 6.5 years for each sex, respectively.
In 100 years, oceans will most likely rise, displacing many people, and it will continue to become warm and acidic. Natural disasters like wildfires and hurricanes will continue to be very common and water resources could be scarce. NASA is researching earth to make observations that will benefit everyone.
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.
By 2030, almost all countries will experience “extreme hot” weather every other year due mainly to greenhouse gas pollution by a handful of big emitters, according to a paper published Thursday by Communications Earth & Environment, reinforcing forecasts that the coming year will be one of the hottest on record.
New genetic findings suggest that early humans living about one million years ago were extremely close to extinction. The genetic evidence suggests that the effective population—an indicator of genetic diversity—of early human species back then, including Homo erectus, H. ergaster and archaic H.
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 (self-extinction) destruction.
They would still probably be small, scrawny, and very generalized. But instead, the mammals were able to evolve and diversify and, well, ultimately, millions of years later, become some humans. So perhaps we would not have been here if it weren't for this extinction event 65 million years ago.
The average global temperature will rise by more than two degrees, causing serious problems. The race for natural resources will be hard, the biocapacity of the world will be exploited more and more. The cities will become richer sources of raw materials for metal than the mineral deposits in nature (urban mining).
Lifespan. Humans will almost certainly evolve to live longer—much longer. Life cycles evolve in response to mortality rates, how likely predators and other threats are to kill you. When mortality rates are high, animals must reproduce young, or might not reproduce at all.
Transhumanism Is the Next Step in Human Evolution.
This took more than 350 million years. There are humans (Bajau Laut- sea nomads) who can hold their breath for longer durations (up to some minutes) underwater. However, it is biologically impossible to evolve (or devolve) to live underwater in a short period.
It's not likely, but humans have the tool kit to evolve venom. Could humans ever evolve venom? It's highly unlikely that people will join rattlesnakes and platypuses among the ranks of venomous animals, but new research reveals that humans do have the tool kit to produce venom — in fact, all reptiles and mammals do.
Humans are not physically designed to fly. We cannot create enough lift to overcome the force of gravity (or our weight). It's not only wings that allow birds to fly. Their light frame and hollow bones make it easier to counteract gravity.
