I will put it bluntly: we can't even terraform the Sahara Desert, the Namibia Desert, and the Atacama Desert to be inhabitable and people are talking about terraforming a planet that has not have enough gravity to maintain an atmosphere for geological time unless that is a very heavy gas: the tail end of Maxwell velocity distribution of speeds will make all those molecules get to the escape velocity and leak to the space after a few million years or less. So If you can breathe sulfur hexafluoride maybe we can. It is a calculation so easy you can do it yourself, it is usually one of the problems or examples that are given in the kinetic theory of gases course. So come back with your feet to Earth and spare me the Elon hype.

Reply to Why does temperature determine the sex of certain egg laying animals like crocodiles? by insink2300
Not only temperature. Animals can even change sex. Each clownfish on an anemone is 25% bigger than the other and usually, the biggest is the only female. If one dies every other gets bigger to fill the gap and if the female dies the biggest of the male becomes a female.
The smaller ones don' reproduce and are undifferentiated. All clownfish have both reproductive organs.
