As I have said many times, I’m a scientific skeptic. That is, I don’t just reject ideas simply to reject them, I actually reject or accept ideas based on the quality and quantity of evidence. I don’t pretend to know much about the Big Bang, but I know when it happened and what happened, but I leave it to experts to hash out the details. No one person can be an authority on every field of science, no matter how many initials follow their name. I’ve already mentioned how hard it is to become an expert in a scientific discipline.
If you read this blog regularly, you’d think I’m completely interested in vaccines, with a little bit here and there on GMO’s, evolution, and climate change. But my own personal interests in biology are, in no particular order, is evolution of man (about which I’ve written some), endocrinology (about which I’ve written nothing), and extinction events (about which I’ve written little here). I have co-authored a couple of articles on Wikipedia on extinction events, have read dozens of books on the major extinction events, and have attended many scientific conferences on mass extinction. I may not have an official degree in extinction geology and biology, but I have spent several thousand hours doing real research in the area.
But I’m pretty certain that the audience for this blog will find my discussion about extinction events to be a bit dull. However, I’m hoping that there is a cautionary tale about science that can be applied to some general rules I have about science.
A couple of years ago, I started editing an article on Wikipedia about the Younger Dryas impact hypothesis. Without going into too many details, it was a hypothesis (named after an Alpine flower) that some sort of comet or asteroid impact struck the ice sheet covering North America, about 13,000 years ago, which lead to the death of the megafauna (mammoths, sabertooth cats, and whatever else lived in North America). It is hypothesized that the impact actually caused a temporary reversal of the retreat of the glaciers towards the end of the glacial maximum.
I actually came across ran the article when I was reviewing some information I had read about climate change from the last glacial maximum (you know, when glaciers covered much of North America). I wanted to know if a bolide impact (meteor or comet) could caused a massive change in North America. Continue reading Science can anger people even in the most obscure fields
