oh,wait a minute I was wrong never mind

I thought all vertabrates had their roots from marine creatures,say the early fish

What issue # is it?

I may not be able to vote but, I would like to say that it's very useful for ecologicol models.

I think this might be true Examples: shrews live a short life,while the tortise lives a long life

WELL, that's definently going to change my vote.(even though I'm only twelve) By the way, that was not sarcastic.

I'm not sure that it will be that soon for space traffic. Your going to need more time many space vehicles into massive production.

The third gender could use a mean of self-reproduting(altough they would be exactly like their parent).

However I have heard of females having only one x chromosone

Oh,Schrodngr's_cat. I know how it feels to let go of a pet. It may not seem like it but, even something as little as returning a turtle will benifit the ecosystem greatly.

I'm sharing my personal opinoin for each one:

A.very Possible

b.has my vote

c.maybe

d.I'm not religous at all, no way

e.unlikely

f.can't think of anything at the moment

I'd have to give John Baez a hand. It seems like that man did a lot reaserch to gather all of this information.

yeah, it was nothing, then it was the fish, then the reptillians, then the mammals(incl. humans) then it will be the time of the insects, wouldnt it be cool if they get realyrealyrealy big

Let's take this scenario (which I think is disturbingly likely to happen):

 

Nuclear war has ended. Just about every continent is a wasteland' date=' mostly with radiation and toxic levels nearly unbearable to homo sapiens species. All mammals including humans become extinct within about 10 years or so.

 

The interesting part comes first: Now that the sections in the food chain and ecosystem where humans and mammals used to be is empty, a new species will most likely take it over within a couple of hundred million years. But which species will natural selection choose to be the next "dominant" species? Highly radioactivity withstanding insects? Bacteria will start to evolve to something more? Just something to think about. [/quote'] I don't think it would take hundreds of millions of years for a new dominent species. Example:After the extinction of the dinosaurs and other major reptiles, mammels and birds took the jump for evolution.
