Hank gets real with us in a discussion of evolution - it's a thing, not a debate. Gene distribution changes over time, across successive generations, to give rise to diversity at every level of biological organization.

Thank you all for all the debate in the comments. I thoroughly enjoyed reading it.

Well, I'd say it's rather logical to assume that there would be an architect, a building crew and also some interior decorators who managed the upholstry. Naturally, it all took a long time to put in place, not to mention planning, or the time needed for an animal to evolve from a single celled organism to eventually have the brains to do the calculations involved and argue over catering all the while.
Science may not disprove god, but I fail to see the necessity of any creator in the process.

I'll send you a pm giving good evidence for God.
If anyone else wants it just reply to this comment.
Also you "DONT" have to be a young earth creationist to believe in Jesus Christ. Many early church fathers didn't take genesis literally so neither should you!

unanswered questions are not evidence of god

And where did the designer came from?
The truth is, there is no god, not only does ALL of science shows otherwise (Yes, ALL of it) but theres not a even a shred of evidence of any kind whatsoever that suports the idea of god (a 3000 year old books is not evidence of the existance of a god, is evidence of the belief of the people of that time in it's existance), religion was an inevitalbe mistake in the path of humanity, but we are too old as a species to continue with it, it's time to end it

I can't even understand how anyone who has evolution explained to them can deny it. So, I'm right there with you.

Icb1250, It is hard for you to see outside your assumptions when your thought is based on illogical faith. Start questioning the ancient storywriter's views and hopefully you'll see no concrete evidence of a creator. It is all just a chain reaction from the big bang. Not design. Sonewhere isn't a valid source. And WTFliers do micro and macro have to do with ecolution? One book with a cross on it is not the world. Darwin went out and got his hands dirty to learn beyond an outdated text.

Very little evidence? Multiple, intricated lineages of well-documented fossils, tons of examples of comparative anatomy, the whole world according to the geographic distribution of living beings, the very fact that all organisms use the same genetic code, with the exception of very simple ones, tons of experimental data showing both evolution in small and large scale is little evidence? Really?
Ok then.

As I said, it's hard to see outside of your assumptions when your thinking is based on those assumptions. Continue to question your views and hopefully you'll see that there really isn't much evidence. As I heard somewhere recently, it's not by accident, it's by design. You're obviously not around scientists all the time, so I can understand why you needed to explain the difference between micro and macro. Interestingly, it was my instructor in marine biology who made me question evolution.
