Are the evolutionists on this board familiar with the fruit fly experiment?
"No Fruit Fly Evolution Even after 600 Generations''
www.icr.org...
Would this then mean, when applying your ideology, that some species evolve, and others do not?
Ken Scam, the owner and operator of ICR, is a fraud. I'm not going to analyze this ridiculous, fraudulent article - that has been done a thousand
times.
Regarding the fruit fly experiments, if you had done some homework, you would know that:
1. The experiments as depicted by Ken Scam are misquoted, misinterpreted and rewritten to suit Mr. Scam's agenda.
2. There is a wealth of research easily accessed on the internet that describe how evolution works in various species, including the notorious fruit
fly.
3. The link below is to a article on the subject. Note that there are a multitude of references which substantiate the various results.
4. Develop some curiosity - reading one stupid article which may support your view is hardly enough research and time investment to elucidate what
evolution science is about.
5. If you want to discuss the science of evolution, you had better do your homework first - because there are many on this forum who understand and
have studied the subject and will counter the lame points you might present.

"Fruit flies[edit]
One of the first of a new wave of experiments using this strategy was the laboratory "evolutionary radiation" of Drosophila melanogaster populations
that Michael R. Rose started in February, 1980.[22] This system started with ten populations, five cultured at later ages, and five cultured at early
ages. Since then more than 200 different populations have been created in this laboratory radiation, with selection targeting multiple characters.
Some of these highly differentiated populations have also been selected "backward" or "in reverse," by returning experimental populations to their
ancestral culture regime. Hundreds of people have worked with these populations over the better part of three decades. Much of this work is summarized
in the papers collected in the book Methuselah Flies.[23]
The early experiments in flies were limited to studying phenotypes but the molecular mechanisms, i.e., changes in DNA that facilitated such changes,
could not be identified. This changed with genomics technology.[24] Subsequently, Thomas Turner coined the term Evolve and Resequence (E&R) [8] and
several studies used E&R approach with mixed success [25]
[26] One of the more interesting experimental evolution studies was conducted by Gabriel Haddad's group at UC San Diego, where Haddad and colleagues
evolved flies to adapt to low oxygen environments, also known as hypoxia.[27] After 200 generations, they used E&R approach to identify genomic
regions that were selected by natural selection in the hypoxia adapted flies.[28] More recent experiments are have started following up E&R
predictions with RNAseq[29] and genetic crosses.[7] Such efforts in combining E&R with experimental validations should be powerful in identifying
genes that regulate adaptation in flies."
