I feel like I am in ground hog day. havnt I already supplied this evidence hereThere is scientific evidence about known "non adaptive influences" in evolution, i.e. the factors of mutations, recombination and genetic drift.
Can you give the scientific evidence "showing that most of the ability for life to change is coming from non adaptive influences such as HGT or in development"?
Horizontal gene transfer is an important factor in evolution of many (not all) organisms, e.g. bacteria.
First of all how did you equate that the paper is saying that natural selection is 50% of the contribution. If you read the paper then you would have understood what it was implying. The paper also said the following which is the basic concept of the entire paper that adaptive evolution ie (natural selection acting on random mutations) does not account for genomic complexity and gene networks are the result of non adaptive forces under weak purifying selection. So at the most natural selection is action as a weak purifier and is not dominant. So that is saying it isn't 50% but is minor, weaker and natural selection on its own does not lead to building gene networks.stevew, this paper does not support your claim of Natural selection (adaptive forces) are negligible and/or minimal when it comes to how life can change and develop. (my emphasis added).
Darwinian evolution in the light of genomics states known biology ("natural selection is only one of the forces that shape genome evolution") and that natural selection is not "quantitatively dominant". This means that natural selection is responsible for < 50% of evolution, not that natural selection can be neglected or is "minimal".
There is no consistent tendency of evolution towards increased genomic complexity, and when complexity increases, this appears to be a non-adaptive consequence of evolution under weak purifying selection rather than an adaptation.
But as I have stated before this paper is consistent with the other ones I have posted which do say that natural selection is minor, and even insufficient.
