What if Earth had 3.5 times our gravity?

How would life survive?

Update:

I mean if it always was and also if it happened suddenly

    Then the acceleration would be 32.2 ft/sec 2 X 3.5 .. You may break your bone when jump up only one meter.

    The actual gravity wouldn't be problematic. What would be a problem is the extreme density and depth of the atmosphere. Photosynthesis would only be possible high in the upper atmosphere.

    I'm sure it would survive just fine. Remember that life would have evolved over millions of years under that 3.5 X's gravity pull. So evolution would have made whatever lifeforms live here now adapted to that extra weight.

    All large animals would die.  Small ones would be OK.

    probably  we'd  all  be  shaped  like  sea  slugs.

    Most people would finally be inspired to go on a diet.

    Life would likely have evolved with that gravity, the bodies of animals and plant structures strong enough to withstand that environment.

    If it just *suddenly* went from 1G to 3.5G, then... I could see most land animals going extinct, a good number of plants also. Those in living in water may not be affected.

    We'd probably all be a lot shorter with thickly muscled legs (if we would be the same shape at all) and I don't think that giraffes would survive.  Life would most likely still survive, it just would have evolved a little differently.
