Re: sensory cells

The simple answer to your question is that science (scientists) are unable to explain how this would have come about. The tenor of your question suggests to me that you are asking a question, the answer to which, you already know. If as I suspect you already know the answer may I ask? Why the questi...

Re: Experimental evidence for evolution

Jackbean wrote Anyway, the 300k random mutations are not those SINEs and LINEs, but those making the genomes different, as you might notice, if you wanted. I think, that the retrotransposones are using some kind of homology insertion, so it's pretty much not so surprising. And even more, it's highl...

Re: Experimental evidence for evolution

You're right there is no theory named as “Current Darwinian theory” anymore than there is an “evolutionary theory” as such. There are different evolutionary theories around. The standard theory known as the Modern Synthesis or Neo Darwinian Synthesis is the one I have referred to as the current Darw...

Re: Experimental evidence for evolution

So are we on the same page as to what theory is being discussed?
The current Darwinian theory that I am referring to is that which I qualified previously and for the sake of removing any misunderstanding I deferred to the Futuyma description.

Is it in order for me to respond to your comments now?

Re: Experimental evidence for evolution

I thought I had made this clear in my précis in a previous post on this thread, however for the sake of clarity let me repeat. “The fundamental tenets of the modern standard theory are random mutations of genetic material followed by...

Re: Experimental evidence for evolution

I would like to add some further evidence to this thread to support the view that the current Darwinian theory is in serious trouble. Support for the gradualism of the standard theory is definitely declining. This is most obvious among developmental biologists who are promoting a “New Evolutionary S...

Re: Environmental effect on Phenotype

There is an inbuilt mechanism that determines the amount of variability in the phenotype. You will find this paper very instructive, it’s conclusions are based on actual experimental data over some twenty years or so. m You can down the full pdf The summary is well worth absorbing. In part it states...

Re: Experimental evidence for evolution

A further response to canolan’s last post As far as I know, once again, the split between macro and micro-evolution is mostly used by ID/creationist rather than biologists who all assume that there is only a continuum (although probably not completely smooth, but certainly not a massive divide) Actu...

Re: Question about Dawkins' The Selfish Gene

As I understand it Dawkins postulates that the gene is the unit of evolution. In other words Natural Selection works at the level of genes. As our knowledge of cell mechanisms has increased this hypothesis is being shown not to be very realistic. The central dogma of biology i.e. DNA makes RNA makes...

Re: Experimental evidence for evolution

canolan And as far as I understand it, the historical contingency is definitely a huge part of the evolution as it is now accepted, and was already part of Darwin's understanding, even if he did not emphasize it in the the origin of species. Granted, my lecture of it was probably contaminated by my...

Re: Experimental evidence for evolution

Hi robsabba I included the ability to transport a molecule across a cell membrane as a "metabolic function." You can split hairs about that if you like, but the point is that these bacteria were now able to make use of a new carbon source that the ancestral population could not. As far as ...

Re: Experimental evidence for evolution

Hi robsabba Thanks for your comments. My response is as follows Creationists hate the Lenski experiments because it blows holes in some of their most beloved paradigms: 1. Natural selection cannot lead to an increase in "information." 2. Evolution cannot produce new functions. As I am neit...
