About Me:
 
I am a house-dad with a BS in Zoology and an MS in Biology (emphasis in Ecology and Evolutionary Biology). I'm interested in providing knowledge about evolution and the public debate about it. I also enjoy discussions about other topics.

I hope to take a civil approach to educating people about the public debate on evolution. I think that if people actually examine the evidence with an open mind, then they will accept (as the experts all do) that evolution occurs. You can check out my videos and some of the ones in my Favorites for some summaries of this evidence.

I try to be respectful of people's beliefs, but I also feel that it is condescending to ignore potential conflicts when they arise or pretend that they don't exist. I think that by engaging in civil discussion, much can be accomplished.

It is my policy not to accept friend requests unless we are at least well acquainted, which doesn't tend to happen online. So, if you didn't know me from face-to-face contact before finding my page, then don't feel bad if I turn down your friend request. Please do subscribe, though!

Peace and Love everyone!

Cool!

Listen 5tonyvvvv, there's no need to hurl insults. It's obvious that you think all atheists are complete idiots with no understanding of how science should be conducted. Clearly that isn't some sort of universal truth, seeing as how most members of the National Academy of Sciences (the top scientists in the US) are atheists. It doesn't matter anyway - I'm just trying to have a conversation with you here.

All I was trying to say is that one shouldn't expect a test-tube to resemble the conditions on early Earth. Modelling chemical processes occurring over billions of years across a whole planet, with tides, lightning, sunlight, etc., is necessarily a bit of a search of what is possible.

Anyway, as I said, if you are convinced of a supernatural or sci-fi origin of life, I'm not really interested in debating it (it can't be tested anyway). I'm a population biologist and zoologist, not a chemist. Please watch my GULOP video and get back to me on common ancestry.

Putting Raw chemicals in a test tube is undirected natural processes, that's what Miller attempted and it failed abysmally!! If you want to manipulate and borrow information, then all you are showing is it takes INTELLIGENCE to COPY life!! You need to take some Biochemistry classes like most atheists! You are clueless, and your atheist assumptions are not based off real testable, repeatable, observable Chemistry!!!
EvoBiologist (1 month ago)
Simply adding "raw chemicals" to a test-tube would be a pretty unrealistic way of attempting to imitate planetary processes.

"You need ALL LEFT HANDED amino acids to start life!!!"

As I mentioned, you don't need amino acids to start life, you need RNA. RNA has the properties needed for simple life - it carries hereditary information and has enzymatic properties. Regardless, you can get all left-handed molecules from a mostly-left-handed racemic mixture.

Personally, I like to focus on the evolution of life, which is where my training is. If you want to argue that a powerful, intelligent being played organic chemist on ancient Earth, be my guest. It seems a bit more far fetched to me than that it happened naturally in a way we just haven't yet determined.

Nature nor can any scientist create life form chemicals!! Starting materials are always a single mirror image for which there is no plausible way to get it that way abiotically.
More significantly origin of life experiments never start with undirected processes, raw chemicals and molecules are never just put into test tubes, and left to self organize!

Experiments today solve nothing! There nothing more than plagiarism of a cell's Design!!!
5tonyvvvv (1 month ago)
Cell's use Left and Right amino acids the metabolic pathways are RIGHT handed! I already mentioned this! But that's not what Im asking! You are assuming like most stubborn atheists! that life got started with both left and right! You need ALL LEFT HANDED amino acids to start life!!! You need to take a Biochemistry class! You know nothing! You present assumptions with ZERO Repeatable chemistry to support it!! Also meteors show nothing! just More Racemic Mixtures!
EvoBiologist (1 month ago)
"MOSTLY left-handed molecules" isn't necessarily even needed, since some bacteria use both chiralities.  The point, though, is that with a high bias to one chirality (as seen in some meteors), most small polymers are likely to be all one chirality, making the chemistry easier.

"nature can never produce 100 percent of either"

Actually, natural organisms produce enzymes that do it all the time.

I'm not sure why creationists like citing an experiment conducted in 1952 (the year before DNA's structure was discovered). Plenty has been done in abiogenesis since Miller-Urey. Furthermore, abiogenesis starts with nucleotides, not amino acids (something Miller & Urey didn't know), making your whole argument irrelevant. Nucleotides are imperfectly hereditary and have enzymatic properties, so arguments about abiogenesis should focus on things like RNA, not proteins.
5tonyvvvv (1 month ago)
"MOSTLY left-handed molecules" is still a disaster! Also nature can never produce 100 percent of either LEFT or RIGHT handed amino acids! and Time will not help! Stanley Miller knew this that's why he carefully protected every chemical reaction he made!!! and used a trap!!! to filter out what he wanted and it was still Racemic!!!!!! With mostly Toxic Tar!! And Experiments today are nothing more than plagiarism of a cell, like what Craig venter and jack szostak do!
5tonyvvvv (1 month ago)
Yes I know but they are still Racemic Mixtures of amino acids!! Also origin of life experiments that are conducted in Controlled laboratory conditions where scientists are borrowing and rearranging information and using activated subunits, templates and synthesizing machines, has nothing to do with the origin of life its more like copying! Not to mention controlled temperatures and PH!! These experiments are not geochemical relevant reactions!!
