Hints: Mars Earth California

But plants grown on Mars may be very different from those on Earth. The lower gravity on Mars, one third of that on Earth means that both plants and animals might grow taller and thinner.
I think we're all familiar with seeing the giant redwood trees of California. They are somewhat unusual here on Earth. They only occur in a few localized places. On Mars, it would be the norm. You would see these tremendously tall, slim trees, possibly with very high canopies on them as well. Animal life could be affected the same way as well. We could see new breeds of animal that we haven't seen before, very tall, thin sheep living on Mars. But again early days, very much speculative.
This lower gravity would also have implications for any people born there.
If humans live on Mars for many generations, they might develop into different forms than humans on Earth. They might be taller, they might be thinner, they might have weaker muscles and weaker bones. It might even be possible that they would not be able to function very effectively on the gravity of Earth. In that case, Mars' society and Earth's society might split and become effectively two different species.
