But there are exceptions. There are a number of species which have changed little over the millenia.
Human beings are now in a different stage of evolution whose patterns are unknown.
Man on the other hand, a specie that evolved from it's previous stage for a million of years ago (?) and got into our intellectual stage for 50 thousand of years ago (?). We are quite adaptable, which is our strength.
If man had been evolutionary stable as sharks, then we wouldn't get anyware evolutionary. We wouldn't sit here and discuss this over the internet, whale making a move of chess now and then.

In 100 millions of years, even the whiles can play chess! 🙂
-if you beat one at a game of chess it would instantly express itself by regurgitating tons of partly digested squid onto your chess board making chess tournaments pretty messy.

Anyway even if it hits tomorrow, there would be not much noticeable effect on our solar system, it's mainly a fight between giant gas clouds. As for the size, its maybe twice the size of our galaxy, not 40X.
In 10,000,000 years the Andromeda galaxy will collide with our Milky Way galaxy. It is 40 times larger than our galaxy so one humdred million years is probably a moot point.

You should watch Nova.

You should get your ears cleaned out before you attribute statements like that to Nova. Think about it. Andromeda is about 2 million light years from the Milky Way. So if it was going to collide with us in 10 million years it would be charging at us at fully 20 percent of the speed of light. Now if you can, try to imagine the amount of energy it would take to get a whole galaxy, one that you claim is 40 times bigger than the milky way, which has over a billion stars in it, where did the energy come from that would make it go that fast? If so, the whole thing would be shifted to the blue because it would be crashing into us at relativistic velocity. You really should think things through before you just spout what you THINK you heard on Nova.

Let's suppose Andromeda galaxy is 40x larger than our galaxy. Our galax, that we call 'the Milky Way', is 100 000 light years across. Then Andromeda would be like 4 000 000 light years across, right? So from the center of Milky way to the center of Andromeda galaxy is 2 500 000 lightyears away from eachother. What does this mean? That the outer rim of our two galaxies has already started to collide.
Has it? No, of course not.
Does Nova know this? Yes, of course.
Does Nova give this horrific desinformation to its viewers and still earn its reputation? No, of course not.
