punchingsack

First of all, I'm sorry for my poor English expression.....:rolleyes:;) So a generation has to be from reproduction..... I get it. Then I meant upcoming , new beings. In trying to reason this statement, I find only paradox. Perhaps you can rephrase it punchingsack? An extremely long word passed, finally the new beings which was able to reproduce was born and reproduced their generations successfully. Their descendants continued and evolved. That's just in my opinion. Since mutating is so random, would there be an aim in randomness? I think the purposeful selection by beings themselves based on natural selection didn't begin until the ability of reproduction invented.

Yes, I mean mouthguards but tooth sockets! I'm sorry for my poor English! Though my expression in English is not good, I can read English good basically! You hit all the problems in my thought of this topic, Craig D, you're great! But why can't stressing teeth make the teeth stronger like stressing hands and fingers, since they are all organism?

I don't think they have to bite each other either.... I mean whether the fixed teeth would reduce their defensive ability even if they wear tooth sockets.

I also want to know initially actually how did the first program of reproduction formed. I just believe it was out of mutation, but I think the mutation must have happened before the initial beings die out, and we know they were very simple beings which couldn't live long. So if they didn't get the ability of reproduction they had to pay the expectation to next generation, but the next generation would be different form them and their birth have to rely on chance of nature. That would be a long long period. Periods by periods finally the generation which was able to reproduce was born and survived. Wasn't the initial evolution of reproduction so aimlessly?

I was searching science forums.

I believe there were and are some aliens with more developed techology who can visit earth easily while some who can do this but not that easily. If the former don't want us to know their actions I believe we can't get any trace of their coming, but the latter may be unable to hide their trace perfectly. I suppose there are some evidence of aliens visiting earth which may be true.

I think every natural light is the most beautiful!

Well...I mean good boxers in IBF, WBA, WBC and WBO. Is it mean if you had many false teeth you would hardly be an excellent boxer?

Thanks!

I hate too

Are boxers' teeth usually the healthiest and firmest with out decayed teeth and false teeth?

How scary is the darkness before I turned on the lamp when I woke up just now!

Hello! I found the science forums very interesting, and I wanna join in the full-of-inspiration communications!
