FYI- I am a molecular biologist. I am not a creationist. I have a problem with "evolution" from single cell microbe to multicellular organism for several reasons: 1. First there is no direct experimental molecular evidence of gene gain in bacteria. 2. From biochemical standpoint, survival ...

Re: How Does Natural Selection Create Ordered Variation?

Try this: A dynamic filter applied to a DINAMIC random input. So it'd be sort of like intersecting waves. They are just as likely to negate as to add up. The law of averages dictates that natural selection can't make any progress then, doesn't it? Think about it this way: You cannot delete establish...

Nice examples JackBean. Another one would be normal human + human with extra Y chromosome... Anyway, all I was trying to say is that because of the ethical considerations compatibility of humans with other species was not and probably will never be tested. Your point on homology, however, may or may...

Depends how you want to go about doing it. From in vitro stand point the main requirement is same number of chromosomes - therefore, Reeves's Muntjac and Sable Antelope could be fully "compatible" with humans. I don't think anyone tested this in vivo...

It's a reference gene of known copy number and/or constant expression levels against which data (such as qPCR) is normalized to enable sample to sample comparison.

Your post reads like you want an idea to create a superbug. Is it possible - yes. What you need is a mad scientist. You asked if it's possible to create an artificial bacterium or virus - the answer is yes. However, why would anyone want to re-invent the wheel? As far as affecting personality, how a...

I already gave you the answer in the other thread. It's beta-hemolytic streptococcus (provided that your previous post correctly identified hemolysis). Look at the links bellow:
