Originally Answered: Will humans ever evolve to breathe in outer space? Will humans ever evolve to breathe in outer space? No, because there is no oxygen in outer space—which is what we need when we breath—not to mention a certain amount of air pressure….
It’s no different in space. A new study from Northwestern researchers finds that microbes aboard the International Space Station are changing genetically in response to the conditions there. It’s no danger to the astronauts there, it’s just a reminder that evolution continues even away from Earth.
Human survival on Mars would require living in artificial Mars habitats with complex life-support systems. One key aspect of this would be water processing systems. Being made mainly of water, a human being would die in a matter of days without it.
We will adapt to life on Mars by using technology, and it would actually be easier and faster to add oxygen to the Martian atmosphere, than for us to evolve to live without it!
A team of scientists at the Tel Aviv University in Israel have found life-form that can survive without oxygen. … Some lower single-celled organisms or eukaryotes are able to respire without oxygen with a process known as anaerobic respiration.
Scientists say there is relatively low risk of near term human extinction due to natural causes. The likelihood of human extinction through our own activities, however, is a current area of research and debate.
We are all destined to become crabs. … It turns out that five different groups of non-crab crustaceans have evolved into crabs in a process known as carcinization, according to a study from the Biological Journal of the Linnean Society as reported by Popular Mechanics.
Fortunately, Martian kids born in a low-g environment wouldn’t suffer from the muscle mass and bone problems that long-flight astronauts do. Unfortunately, the biggest possible problem with your Galactic Globetrotters may surface if low-gravity-born humans tried to return to Earth.
It might seem like a fantasy to float weightlessly through the air but practically, the human body would go through negative change, such as muscle and bone atrophy while living in zero gravity. Even the rivers, lakes and oceans on Earth wouldn’t stand in zero gravity, without which humans cannot survive.
Approximately 300,000 years ago, the first Homo sapiens — anatomically modern humans — arose alongside our other hominid relatives.
The only realistic scenario for the evolution of two species out of ours would probably be if we expanded beyond our home planet and then lost contact with the settlers. If both populations survived long enough – much more than 100,000 years – we might see divergence and maybe two species of humans.

Adding a pad of high density material (heavy metals, or iron) could increase gravity since gravity decreases by the inverse square, having the mass as close possible to the astronauts feet would help.
At present, Mars’ water appears to be trapped in its polar ice caps and possibly below the surface. Because of Mars’ very low atmospheric pressure, any water that tried to exist on the surface would quickly boil away. atmosphere as well as around mountain peaks. No precipitation falls however.
It’s relatively cool with an average annual temperature of -60 degrees Celsius, but Mars lacks an Earth-like atmospheric pressure. Upon stepping on Mars’ surface, you could probably survive for around two minutes before your organs ruptured.
Depending on the projection of world population in the forthcoming centuries, estimates may vary, but the main point of the argument is that it is unlikely that more than 1.2 trillion humans will ever live.
“Effectively, there used to be large animals everywhere, and there would be large animals everywhere around the globe without human involvement.” His research has revealed that without humanity’s heavy species impact, the central United States, and parts of South America, would be the most megafauna-rich places on …
Without the human race, nature would not only survive, but it would thrive. Although our legacy of pollution, nuclear remnants, and climate change will impact nature long after we are gone, eventually nature will heal and the planet will become abundant with diverse animal and plant life.
There is nothing in human evolution that required gills, and nothing in environmental challenges that would require them. Humans don’t need them. You don’t go about evolving. Evolution is not directive but occurs when organisms adapt to thrive in their environment.
Scientists have recently observed for the first time that, on an epigenetic level, astronauts age more slowly during long-term simulated space travel than they would have if their feet had been planted on Planet Earth.
there are no hours in space. an hour is a not too convenient unit that is 1/24th of one revolution by the earth on its axis of rotation. Earth gravity is not that strong so it should only dilate time by a little bit.
“There are many risks to conception in low or microgravity, such as ectopic pregnancy,” Woodmansee said. “And, without the protection of the Earth’s atmosphere, the higher radiation levels raise the probability of birth defects.”

Astronauts are trained individuals at the heights of human fitness, backed up by a lot of research and experience to guide them, but a human infant has none of those qualifications, making it far more difficult to survive. Even if it survives, it’s highly improbable that it would be a healthy individual.
When gravity disappears for 1 second the outwards force balanced by the gravity would be released causing a massive explosion. In other star systems with more immense stars and natural phenomena such as pulsars and and especially black holes the explosions and expansions would be greater.
