If the Earth is as big as Jupiter,would we still look the same?

Answer 1

No, because of different gravity and environment, our sizes and indeed our whole beings would be affected.
Every aspect of an environment has an effect on the way a species deveops and evolves.
Earth's gravity would be tremendous and we probably won't be bipedal, more likely we'd be flatter and crawl (in a manner of speaking) like a slug.

Answer 2

We wouldn't look at all the same, because the high gravity and consequent massive pressure would be such a different environment that, assuming that the planet was otherwise hospitable to life (unlike Jupiter, which has intense radiation and horrific temperatures), would have likely resulted in much different evolutionary pathways.

Answer 3

i would agree here, even if "big" means by both mass and volume or by volume only. If we go with the first, then gravity would be stronger, resulting to larger muscles and bones to support the body in a much more powerful gravitational field. we could have larger bodies then, but smaller brains and heads (since we do need to lose some weight in the process). If we go with the volume-only option, we have less gravity, so our bodies don't need to be like they are now. We would then have larger brains (and heads).

Answer 4

There are a number of other variables you'd have to take into account, but by and large it's quite unlikely, because of the differences in gravitational pull on our bodies - evolution would have taken a different pathway to deal with that, e.g. lower centres of gravity, stronger muscles, differences in bone structure and so on.

Answer 5

No, everything would be totally different. Gravity would be stronger, so we would have to be much stronger than we are now just to go about normal activities. There would no doubt be other differences too.

Answer 6

hopefully
do you mean, the earth is getting big? yes we will managed it with technology

if the gravity is too strong, i guess a life form is harder to survive

Answer 7

Ok listren up. Gravity scaled up wold mean that we would be stockier
