That's because of your hopeless ignorance. If you'd bother to learn biology, you'd see that I actually know quite a bit. There are better folks on this forum (haven't seen the mite guy around for a while, sadly), but I'm not bad, if I do say so myself. Again, I've actually done it--which means while YOU may not like the state of my knowledge, experts in the field do.ChrisBFRPKY said:I'm starting to think you know more about chicken farming than you do about describing species.
http://www.sciencedaily.com/releases/1998/07/980721081204.htmFirst, your observations about DNA from dung. The only things I've determined from dung is diet and parasitic identification or infection.
You are wrong. Demonstrably so.
The fun part will be to see if you admit it--you've made such as stink about skeptics admitting error, after all, that we can only expect you to humbly admit you were wrong. I'm not betting on it.
Nope. Mammalian blood is predominantly red blood cells, which lack nuclei. Only white blood cells have nuclei, and they aren't nearly as numerous. This is fourth-grade biology stuff; pick up any Health Class textbook in the USA and you'll see it. There IS DNA in blood, but not nearly as much as you suggest. It's not impossible to get DNA out of blood, certainly, but it's just about the last choice for dobily fluids in regards to DNA analysis.Second, Blood contains TONS of DNA. Your suggestion otherwise is incompetent.
See what I did there? I supported my conclusion with evidence. Please begin to do so in this thread. Your tactic of mere assertions is becoming tiresome.
This is standard stuff. It's about as incredible as orbiting a planet--yes, the technological achievement is astounding, but it's hardly new. My boss was doing this stuff in the 1980s, and it was considered routine then.Incredible if accurate.
Probably, regarding the laboratory protocols. As for sufficient background information, you'd be surprised how often people don't. My company routinely ships out samples we simply don't have the expertise to deal with, and many researchers are adverse to admitting they don't know something. Sad, but unfortunately true.Drewbot said:I think we can assume Dr. Sykes has 'sufficient background knowledge' and 'adequate laboratory protocols' in place.
Again, biologists tend, in my opinion, to over-estimate the utility of DNA evidence. I'm not saying they WILL in this case; I'm withholding judgement. I'm merely presenting potential problems that may arise. Again, the math WILL return a result; it cannot do otherwise. The issue, as I said, is interpreting the result. And we still have serious trouble placing known species in phylogenetic trees (check out early rodent evolution, for example).Dr. John Hawks when asked "If you had DNA from an unclassified animal,would you be able to use those results to place where it belongs in phylogenetic tree?"
Answered: 'Yes, that would be no problem at all.'
