Do heavier animals sustain heavier impacts better or worse?

Suppose I were in a minor accident. I was standing still weighing 50 kg. The vehicle weighed 500kg and was only going at 5 kph...

Would an elephant weighing 5000 kg need to be hit by a 50000 kg weight travelling 5 kph in order to feel what I felt? Or do I need to scale up the speed too?

(Disclaimer: despite my choice of phrasing, no elephants shall be hurt by gigantic weights in the making or answering of this question :P )

What effect(s) would result from significantly adding to the world's mass?

As our technologies improve it's only logical that industry will look to asteroid mining as a source of rare minerals & elements that doesn't damage the environment. In bringing these materials to earth the mass of the planet would inevitably increase. What are the dangers?

Evolution?

I'm not religious, but don't believe in Darwinian theory. I believe that evolution has to be use based somewhat along the lines of Lamark or perhaps Lysenko.

Can anyone explain this one: The Bee Orchid pollinates and breeds by attracting bees to it and does so by looking surprisingly like a bee. How is this possible, if mutations are random? The orchids mutations were assumably not conscious, and an orchid cannot know what a bee looks like.

Assuming the first mutation, which had the orchid start looking vaguely like a bee occurred randomly. Further mutations making the orchid look more like a bee through "genetic drift" must become even more so improbable if the orchid can't know what a bee looks like.

I don't think that random mutations result in evolution; it must be environmental factors that "COMPEL" the mutation.

Any comments.. sensible people only. no Christian lunatics please.

Further to my question on the big bang......?

If I accept that as i am told to travel at the speed of light would take more fuel than there is matter in the universe, how did matter ( all but sub atomic matter ) travel at these speeds during the early expansion of the universe when there was not enought matter to fuel the explosion and create the force..... Sorry I am just sitting at my desk thinking these things over..
