Notes in practical evolution

filed under: @ 19:32:02

I'm going to start a series of articles about the common sense aspect of evolutionary theory. What about evolution is actually practical knowledge? How can it help people understand things relevant to their own work or lives? This goes beyond the gee-whiz, “Where do we come from”, National Geographic-kind of interesting question. That's nothing more than a framework for idle curiosity: it presents evolution as a kind of adjunct or substitute for religious inquiry. I want to convey something more important. It matters that we evolved. The process of evolution allows scientific predictions that we can use to make things happen, to make them work. Evolutionary biology illustrates and informs us about decisions that society will have to make in the next 20 years; decisions that I want my students to be informed about. When I teach evolution, I emphasize a common sense perspective. Understanding a science means knowing the boundaries of the possible.

Notes in practical evolution

John Hawks will publish on his blog an essay every Friday on evolution with a common sense perspective. Very interesting.

Algorithmic Inelegance

filed under: @ 19:30:21

Complexity in living things is a product of the lack of direction in evolutionary processes, of the accumulation of fortuitous accidents, rather than the product of design.

The rise of mammals

filed under: @ 09:52:43

The mass extinction that wiped out dinosaurs and other life 65 million years ago apparently did not, contrary to conventional wisdom, immediately clear the way for the rise of today's mammals.

Evolution and mountains

filed under: @ 09:47:03

Two articles on Nature:

Most people tend to think of the tropics as the hottest scene on the planet when it comes to spawning new life. But Canadian zoologists have found that it is actually the world's temperate zones where new species evolve and become extinct the fastest.

Life is faster in the temperate zone

A three-dimensional model of our planet's plate tectonics could help to explain why the Andes mountain range is taller than geologists would predict: it could all be down to the long length of the South American continent.

Why are the Andes so tall?
