Our planet might remain habitable for roughly a billion years. If we survive as long as the Earth stays habitable, and based on the scenario above, this would be a future in which 125 quadrillion children will be born. A quadrillion is a 1 followed by 15 zeros: 1,000,000,000,000,000.
In about one billion years, the solar luminosity will be 10% higher, causing the atmosphere to become a "moist greenhouse", resulting in a runaway evaporation of the oceans. As a likely consequence, plate tectonics and the entire carbon cycle will end.
Just as our planet existed for more than 4 billion years before humans appeared, it will last for another 4 billion to 5 billion years, long after it becomes uninhabitable for humans.
The model, called Mindy, provides a terrifying glimpse at what people could look like in 800 years if our love of technology continues. According to the company, humans in the year 3000 could have a hunched back, wide neck, clawed hand from texting and a second set of eyelids.
The fossil record indicates that Homo sapiens has been around for 315,000 years or so, but for most of that time, the species was rare—so rare, in fact, that it came close to extinction, perhaps more than once.
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).
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.
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.
There will be "far worse extreme weather events than those we see today. withering droughts, epic floods, deadly hurricanes, and almost inconceivably hot heatwaves; a typical summer day in midlatitude regions like the U.S. will resemble the hottest day we have thus far ever seen." Dr.
India will overtake China as the most populated country on Earth. Nigeria will overtake the US as the third most populous country in the world. The fastest-growing demographic will be the elderly: 65+ people will hit one billion by 2030. We will need to figure out ways of how to accommodate 100+ people at work.
Scientists have found a way to lengthen worms' lives so much, if the process works in humans, we might all soon be living for 500 years. They've discovered a "double mutant" technique, when applied to nematode worms, makes them live five times longer than usual.
? We'll get a 60 centimeter rise in sea levels. ? Extreme weather events will multiply and become more intense as temperatures increase. ? Droughts will become common in most of Africa, Australia, southern Europe, southern and mid US, Central America and the Caribbean, and parts of South America.
Worldwide there are roughly two new mutations for every one of the 3.5 billion base pairs in the human genome every year, says Hodgson. Which is pretty amazing - and makes it unlikely we will look the same in a million years.
We will likely live longer and become taller, as well as more lightly built. We'll probably be less aggressive and more agreeable, but have smaller brains. A bit like a golden retriever, we'll be friendly and jolly, but maybe not that interesting. At least, that's one possible future.
The Short Answer:
Earth's gravity is strong enough to hold onto its atmosphere and keep it from drifting into space.
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.
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.
Transhumanism Is the Next Step in Human Evolution.
2070 will be marked by increased acidification of oceans and slow but remorseless sea-level rise that will take hundreds if not thousands of years to reverse – a rise of more than half a metre this century will be the trajectory. “It's a very different world,” Thorne says.
The group of world-renowned climate experts explain how, even if countries hit net zero by 2050, CO2 concentrations already in the atmosphere will leave “little to no room for manoeuvre”, and that there is only a 50% chance of holding global temperatures at 1.5°C above pre-industrial levels.
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.
Researchers have announced the naming of a newly discovered species of human ancestor, Homo bodoensis. The species lived in Africa about 500,000 years ago, during the Middle Pleistocene age, and was the direct ancestor of modern humans, according to scientists.
The First Humans
One of the earliest known humans is Homo habilis, or “handy man,” who lived about 2.4 million to 1.4 million years ago in Eastern and Southern Africa.
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.
