I often get requests from students to answer questions about biology — typically, they’ve been told to write to a scientist and get a response, and somehow they’ve picked me. I try to answer them, but due to the number of requests, I usually only give brief answers. Here’s an example:
Dear PZ Meyers,
Yeah, I know. Somehow my name is impossible to spell correctly. I’m resigned to it and just let it slide nowadays.
My name is XXXX and I’m a 19-year-old junior in college.
Now this part was a little weird. They’re a college junior…but the questions are more like what I’d expect from a grade school kid. But OK, I’ll go with it.
I know you might be quite busy, but I wanted to ask if you could assist me with a simple assignment for one of my college courses dealing with the origins of life on earth. I am required to ask anyone (preferably someone who is science-minded such as yourself) the following four questions:
Here are their four questions, and my short answers.
1. How long are the days in Genesis 1? Why?
The bible is not a science textbook, and trying to pin a specific length to a vague metaphor is a category error. All that matters is that the events described in Genesis 1 cover a period of billions of years, and are presented in an incorrect order.
2. How old is the earth and life? Why?
The Earth is approximately 4 1/2 billion years old. Life arose approximately 4 billion years ago. We have multiple corroborating lines of evidence from physics and astronomy that confirm the first date, and genetic and trace fossil evidence confirms the second.
3. Did man and apes share a common ancestor? Why or why not?
Humans ARE apes. Yes, all modern primates share a common ancestor. The last common ancestor of humans and chimpanzees lived roughly 6 million years ago. Again, this is confirmed by molecular and genetic evidence.
4. Were Adam and Eve real people? Why or why not?
No. Humans have more genetic diversity than could possibly arise by divergence from only two ancestors; also, a population of 2 lacks the genetic diversity that would allow the population to survive. Population genetics tells us that the greatest population bottleneck in our history occurred about 80,000 years ago, when the human population was reduced to 15,000-20,000 breeding pairs. Not two.
I fired those off, and thought I was done. I just got a thank you from the student, though, which was nice.
Dear PZ Meyers,
I hope you’ve been doing well.
First, I’d like to thank you again for helping me with this assignment because I got all the points on my grade for it! As promised, my professor sent some comments (quite a bit in fact) for me to read over and share with you. I don’t know how much you’ve heard already, but if you have the time, you can read them over and give a reply. I’m not as knowledgeable in this scientific area but I do believe in God and that his Word is true.
Uh-oh. Their professor did send a reply.
Jebus, did they. 11,000 words of pure, ripe, grade-A creationist bullshit. I’m exhausted just looking at it.
