Re: Re:

All DIRECT evidence of evolution available to date is evidence of gene LOSS. Yet again, I'd like to see citations that show that "ALL direct evidence of evolution available to date is evidence of gene loss," not just you cherry-picked citations. If you don't like these inferences, please ...

Re: Re:

I already said in another post that this article has no PROOF of anything. Reading a long summary of other people's conclusions does not help... The idea is that this one review paper provides citations to the primary research - I was trying to make it easy for you. Do an exercise - trace the actua...

http://www.isogg.org/tree/Keller%202012%20Oetzi%20Iceman.pdf It's an example of archaeological evidence. When some gene found in today's human genome in not found in the genome of ancestor (mummy), it is said to be a "new gene" gained = indirect evidence. I quickly scanned through the art...

Re: Evolution or De-evolution?

I would like to start by clarifying the terminology for this post so that everyone is on the same page… Facts: 1. Molecular evolution – refers to molecular changes over time (ex. Genetic mutations, lateral gene transfer, etc.) that have been proven to be able to affect phenotype changes (ex. Diseas...

Re:

I know what deduction is. I was hoping to get an example of archaeological evidence you claim deduces "new gene events". O.K. Then read this: m It's an example of archaeological evidence. When some gene found in today's human genome in not found in the genome of ancestor (mummy), it is sa...

Re: Genetics Hard problem!

Based on the information in Experiment II, estimate the minimum genetic map distance between the two genetic loci. (Note: One genetic map unit (m.u.) gives a recombinant frequency (RF) of 1 percent.) I scanned the whole passage in the attachment. Answer is 34 m.u. This is what I did: B+/ba x ba/ba ...

Re: Is evolution as simple as we think?

Thank you for your reply, but my question required a yes or no answer. By replying with "not exactly", I still do not know what your point is. What would be direct, reproducible evidence for the spontaneous appearance of a new gene with a novel function in a genome? And how can archaeolog...

Re: Is evolution as simple as we think?

I'm going to jump in here to get something clear. Cat, are you claiming that there is absolutely NO evidence for the spontaneous appearance of ANY new gene with a NOVEL function in ANY genome? Not exactly. I am saying that there is no DIRECT, reproducible evidence of it. You can deduce "new ge...

Re: Re:

Your are just wrong. There is tons of evidence. See Taylor, J.S. and J. Raes. 2004. Duplication and divergence: the evolution of new genes and old ideas. Ann. Rev. Genet. 38:615-643. This paper is nearly ten years old and only took me a minute to find! Just because you don't want it to be true, doe...

Re: Evolutionary mechanisms

Since natural selection tends to reduce variation does it also hold true at the ecological level in fauna flora interactions? Using cat's example of slow rabbits getting eaten and reducing variation of this species, will this help increase variation of certain plants since there will no longer be c...
