Is there any evidence of life on Mars?
Small spheres were observed in the meteorite which the scientists in 1996 claimed were the fossilized remains of bacteria. However, they are roughly 1000 times smaller than the smallest bacteria on Earth, so don’t resemble any life thought to be possible.
Could there be intelligent life on other planets?
Sophisticated life forms are relative newcomers on Earth compared to bacteria. Because the environment of other planets is more primitive, life on other planets (if it exists) may be primitive and unsophisticated. If not, life would have developed the ability to withstand otherworldly environments as well as finding material for nutriment.
Why is Mars important in the study of evolution?
Mars is of particular interest for the study of the origins of life because of its similarity to the early Earth. This is especially so since Mars has a cold climate and lacks plate tectonics or continental drift, so has remained almost unchanged since the end of the Hesperian period.
Will humans ever be able to walk on Mars?
Since then, no one has flown so fast nor walked so high. NASA is now preparing for a human mission to Mars, but if our descendants ever shrug off their terrestrial bonds, it won’t be Homo sapiens who leaves, but another, more intelligently designed species. We’re not fit.
What happened to the water on Mars?
Mars is small, and so cooled off very rapidly. Mars was sufficiently cold for water to be absorbed into the ground and freeze like tundra in the Canadian northwest. Today scientists estimate that a large amount of water is frozen into the surface of Mars.
What would life be like on other planets?
Because the environment of other planets is more primitive, life on other planets (if it exists) may be primitive and unsophisticated. If not, life would have developed the ability to withstand otherworldly environments as well as finding material for nutriment. We might have to imagine what such creatures would be like.
