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.
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).
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.
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.
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.
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 evolving to fly is incredibly unlikely due to our existing physical makeup and the lack of evolutionary benefit. 🐒 Humans are part of the simians, a larger group of primates that includes monkeys, lemurs, and apes.
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.
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.
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. Shichun Huang is an associate professor of Earth and planetary sciences at the University of Tennessee.
The business leaders displayed a sharp divide over just how dangerous AI is to civilization. While 34% of CEOs said AI could potentially destroy humanity in ten years and 8% said that could happen in five years, 58% said that could never happen and they are “not worried.”
Of course, the Earth can and will survive just fine without us. Life will persist, and the marks we've left on the planet will fade faster than you might think. Our cities will crumble, our fields will overgrow and our bridges will fall.
Fifteen Dog Breeds That Have Become Extinct
Breeding has also played a factor in which dogs have become extinct. As you'll learn, many times, extinct dogs didn't drop off the face of the earth but were rather bred to create new breeds that are still around today.
There are three times in history during which humans nearly went extinct. Here's what threatened us, and how we survived.
The short answer is that a variety of big mammals would be on top -- both the big ones we know and love today, and some even bigger ones that became extinct shortly after people moved into their territory. No one species would rule the entire planet.
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.
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.
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.
In skydiving, we talk about 'human flight' a lot, and wingsuiting is the closest thing to actual human flight there is.
“As an organism grows, its weight increases at a faster rate than its strength. Thus, an average adult male human would need a wingspan of at least 6.7 meters to fly. This calculation does not even take into account that these wings themselves would be too heavy to function.”
All animals have genes that decide and control the development of organs. Due to these genes, it is impossible to find humans born with wings. Our limbs will develop according to the instructions encoded in such genes.
World population is expected to increase from 7 billion today to over 9 billion in 2050. A growing population is likely to increase pressures on the natural resources that supply energy and food. World GDP is projected to almost quadruple by 2050, despite the recent recession.
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.
Though the climate of Earth will be habitable in 2100, we will be experiencing new extremes. Each decade will be different from the previous and next decade. The climate future could be quite bleak.
