Re: Theories - Origin of Life

Luxorien you wrote But if we can agree that a random mutation might confer a benefit for the mutated organism, then we can agree that the variation on which natural selection acts is, at least in part, the result of random mutation. Please don't take my statement any further than what I have said. I...

Re: Theories - Origin of Life

Luxorien For the sake of clarity, and I have stated this before and will probably have to continue ad nauseam. My position is not that random mutations do not happen. They do. Does NS act upon random mutations. Yes I believe that may also happen. In other words, does evolution (change over time) hap...

Re: question for evolutionary biologist.

Rap Sorry for the delay, I have only limited time to devote to this forum. Thanks for clearing up my misunderstanding. Good to know your are a computer programmer. I have done some myself, mainly on 4GL relational database stuff As far as the species point is concerned, the Venter Institute has a FA...

Re: question for evolutionary biologist.

Jackbean I'm sure you will show me, where Venter said that this is proof of creation by God. Or is another example of your favourite quote mining? Where have I stated Venter said that this is proof of creation by God Is raising this sort of fabrication, the only way you can debate? Maybe your hope i...

Re: Theories - Origin of Life

Now that the Olympics and paralympics are over I am able to put away my armchair and pop corn and continue. One of the reasons I was amused at the wiki statement that a gene evolves via natural selection has to do with their understanding of what a gene is. Their definition is A modern working defin...

Re: question for evolutionary biologist.

Jackbean It is Venter's claim that his team “created a new species without any biological precursor.” It was he that referred to this as a “proof of concept” If you have an argument with that, it is not with me but with real biologists and engineers. Now your comment And even if they have created so...

Re: question for evolutionary biologist.

Darby One of the main theories is that the first main metabolic molecules were RNAs, which can template proteins as well as be active themselves. How you get from such a start to the system seen now hasn't, so far as I know, been worked out. I agree with you about the RNA world having been one of th...

Re: question for evolutionary biologist.

wbla3335 The only alternative to abiogenesis is creation, which is not exactly free of fairies. As I said, no one knows. The documentary crews weren't around, so all we can do is surmise. Some of us choose to believe in gods, some don't. You are quite right in that the only alternate to abiogenesis...

Re: question for evolutionary biologist.

Rick There are two ways you can address this issue. The first is to look at it in a scientific way as you appear to be doing, however it is often mistaken as a chicken and egg argument. The reality is that the Cell is the basic unit of life, therefore it was the Cell that had to have been in existen...

Re: Theories - Origin of Life

I apologise for my long abstention from this forum, but illness has taken it's toll. However I am somewhat better now so may I perhaps continue to engage and no doubt irritate. Luxorien I did say I would put out some information on antibacterial resistance so here it is for any further discussion. A...
