Re: Why are leaves green?

Quinten. Thanks for that. I remember reading Goldsmiths theory back in the late 80's/early 90's (showing my age now ) and for me it conjured images of life trying to overcome the problem of light only being on a certain point of earth for limited hours of the day. I was of the opinion that the need ...

Re: human age and biology

One must not confuse the increasing average lifetime expectancy and the maximum age a man can reach. They are not linked to one another Good advice, it's something that got me through my exams many years ago. You may believe there's a magic number, a limit say, but personally I'm willing to accept ...

Re: Experimental evidence for evolution

I am just now joining this long and interesting thread You are half right, it's certainly long. It's been fun while it lasted but unfortunately I shall have to take my leave and do other things. I'll hope to check back now and again to see if there's an answer to the question: why are leaves green?...

Re: Experimental evidence for evolution

You appear to be (and I would conclude unintentionally) blurring the distinction between variation within species (ie [email protected] finches) and speciation. Ok give me YOUR universally accepted definition of a species. In other words YOUR definition of a species, that is also universally accepted as THE...

Re: human age and biology

There is no scientific evidence that supports any human surviving for much more than 100 years. People older than 100 years are not scientific evidence? In the context of the question "do you think human body is able to survive 930 years" I'm surprised you conclude by "much more than...

Re: human age and biology

Q: Is human body able to survive for 930 years? There is no scientific evidence that supports any human surviving for much more than 100 years. However, if Adam was on a spaceship that was travelling at or very close to the speed of light then an observer on earth... oh forget it. - Q: Is man so st...

Paleontology is a lottery in the sense that: 1) Funds need to be raised to support the work. 2) On average you won't find anything to justify the expenditure. As opposed to drilling for oil where: 1) Funds need to be raised to support the work. 2) On average you will find something to justify the ex...

Re: Experimental evidence for evolution

Species origin by the Darwinian mechanism of random variation and natural selection cannot be, and I hold that the accumulating and now indeed the overwhelming evidence of actual science, demonstrates this. I guess the only explanation for my failure to be overwhelmed by such evidence is that I can...

I think it's pretty clear why plants appear green, the question that still seems unanswered is why plants evolved to be green and not (for example) black?

Re:

what's all the stuff about exercise converts fat to muscle? Well if you excercise you burn energy, which can force the body to use some of it's fat reserves. Also you will damage and therefore force regrowth of muscle. There isn't a direct conversion, but the end result of excercise is less fat and...
