Evolution

<< < (3/4) > >>

PurpleYouko:
I think it is just that if they were all omnivores then the competition would be too strong so they would all mostly starve.

If one species manages to evolve in such a way that it becomes more efficient at extracting food from a particular source (take humming birds) then it has no competition so it has the chance to thrive.

Evolution exploits niches. In a world without niches then they most likely would all become average omnivores.

Numsgil:
Yeah, that's the general overview, but if I ask you the mechanics of how animals find niches, it'd take you a minute.  The links schvarz provided helped me out, but this was before then.

If an animal eats grass, why doesn't it learn to eat meeat too?  Well, to do so must mean it eats grass less well.  Or maybe not...  Arg!

Using google always gives me a headache.

PurpleYouko:

Just remember what you keep telling Bots.

Evolution has no objective!

If something eats grass really well then it has no need to eat meat or anything else.

Also in order to efficiently eat meat it would have to change the type of teeth that it has so that it can tear instead of grind. This would make it less efficient at eating grass so the mutation would tend to be selected against.

It would be possible that such a mutation could be selected for if the particular animal that first gets it, also develops the tendancy to attack other creatures (aggressiveness). If this makes it more successful then it will pass those gense on until we get a herd of carnivorous cows.

It's just random dude!

Most random changes de-tune the species.

Just what my sig says :)

I got my stuff from my own (old dont have no more) evo. sim.

Basicaly a robot will take a long time to go from "doing nothing and spinning and shooting"  to  "chasing food and others" just because it evolves little bits of code per reproduction.

Although this problem can be fixed like this:

(This was talked about somewere in the other forums)

A robot keeps a gene [you]inactive[/you] and mutates it. The gene may actualy build up a nice code structure before the bot activates it.

So I am all for deactivating and activating genes.
