If you guys want, I can respond with this...
I'm surprised I've never seen anything written on the simple illogic of the possibility of at least 3,000,000 different kinds of animals living on earth (this is the figure estimated in the 1950's. Who knows what it is now) (not to mention all the other forms of life on earth) of which probably a very high percentage reproduce sexually, how all of them just happened to "evolve" at the same rate and at the same time and in the same locality in order to reproduce.
Hi Lorraine. My name is Ben, and I am one of the resident biologists on Mike Wong's messageboard. I am a grad student in behavioral ecology at the University of Texas, Arlington. I must say that your email to my friend was full of misconceptions about biology and evolution that I feel compelled to clear up.
First the current figure of species on this planet is around 1.5 million described, but between 10 and 50 million extant, with billions having existed in prior geologic time periods.
Sexual reproduction evolved once, in one lineage of single celled eukaryotes (organisms with a cell nucleus)
There are several theories for how this happened, but my personal favorite is that it happened via a mutation that botched cell division so it happened twice instead of just once, but didnt replicate the chromosomes. One of the daughter cells then ate one of the others and incorporated its DNA. A few million rounds of division, and eating and you get sexual reproduction that can then evolve into its variety of forms that we see today. And there are several forms, different sex determination systems, etc that we see in nature. There is pretty good evidence for this, as well as other possible explanations.
It does not require and two animals evolved sexual reproduction at the same time, or that all animals evolve at the same time. They dont, as the fossil record and data from genetics shows us.
Now there's been so much written about just the simple(?) protein and DNA and the horrendous improbability of just ONE of these evolving and the statistics for just one of these in terms of probability are simply mind boggling. But now take a look at the at least 2+ million animal life forms that reproduce sexually and now there is a problem that probably couldn't even be calculated mathematically.
Except that sexaul reproduction did not evolve in animals. it evolved in single celled organisms before aniamsl or plants existed. If you would like, I can give you a basic primer in how evolution works, and the evolutionary history of life on this planet.
As for proteins, you are operating on a flawed understanding of protein evolution. They dont just snap together all at once like what is assumed in the statistics you refer to. Yere, I am going to link you to a quick video that explains basic protein evolution and the origin of life.http://www.youtube.com/watch?v=U6QYDdgP9eg
The point is, self replicating nucleotide strands (like primitive DNA) started out not doing anything but increase the possible size of lipid vesicles. But they started to be folded into shapes and started to do things, and eventually could have started to assemble proteins (your ribosomes in your cells are RNA that do just this, and they can be broken down into even simpler macromolecules that do the same thing, but less efficiently) that performed functions for the hyper-primitive cell, like let nucleotides in through the bubble, or helped them attack other bubbles.
All of this can be demonstrated to work in a lab.
Sadly, I find the continued blindness of people who cling so tenaciously to the “evolution theory” in spite of all the knowledge that has been gleaned over the last 30 or so years in molecular biology as well as all the other sciences, a confirmation, once again, that the Bible is right where it says:
Except that molecular biology is the strongest confirmation of evolution we have. We can cross reference divergence times we get with genetics against geologic events and the fossil record, and they jive perfectly
They know the truth about God because he has made it obvious to them. For ever since the world was created, people have seen the earth and sky. Through everything God made, they can clearly see his invisible qualities—his eternal power and divine nature. So they have no excuse for not knowing God.
Actually, life on earth is jury rigged, redundant and inefficient. Are these qualities you associate with an engineer? No. In fact, if you want to start basking in the glory of god, the sword cuts both ways. What kind of god do you worship that created gamma ray bursts that can wipe out life across hundreds of planets, diseases like Ebola, AIDS and Small pox, even inluenza has killed more people than every war in human history combined.
You might want to put this question up on your arguments page to see what feedback you get. But I suspect you probably won't because it might jog some people out of this illogical, non-nonsensical evolution mindset, and we couldn't have that now, could we?
