Re: Effect of temp. on cellular respiration

The enzymes in general get more and more active as the temperature increases. This would be true till the temperature reaches up to 45 degree Celsius (in general for humans)... But at 65 degree Celsius most of the intracellular enzymes are denatured. So as the temperature increases, the cellular re...

The same way that pretty much any amino acid sequence (or better yet, nucleotide sequence) of sufficient length can be used to identify any organism. :)

For #5, I would mention that most mutations actually don't produce new genes, but rather cause changes to existing genes. The most common way for a new gene to be created is a gene duplication, which leads to two or more identical copies of the gene. Natural selection will ensure that at least one o...

Re: Any SOLID arguments against evolution?

NickT: "link" is a vague term, so I can't really tell what you mean. Lucy (m) ) is a particular Australopithecus skeleton which is unusually complete, and Australopithecus may be a common ancestor of the great apes (including humans - although the common ancestor between humans and chimps ...

Re: Theories - Origin of Life

While I'm waiting for you to finish, I thought I would just clarify this: Since you see no difference in the views I have presented, you have answered my question. Actually, I can't figure out what the views you have presented are . I only said that among the statements that you quoted, I did not se...

Re: Theories - Origin of Life

yes I intend to address your entire post. But I do have to start somewhere don't I? I can wait for you to finish; in attempting to devise answers, I think you will be able to get closer to resolving any confusion. I see no contradictions or "differing views" in any of the phrases you have...

Re: Any SOLID arguments against evolution?

These are the questions I was talking about. Now - if such an experiment was repeated in a laboratory, what would you think had been demonstrated? Or suppose some different criterion were met instead: - if the experiment showed that a self-replicating but non-cellular entity had been produced? - if...
