Evolution’s Third Replicator?

Friday, July 31st, 2009

This article argues that we are seeing a new form of evolution emerging, after genes and memes.

WE HUMANS have let loose something extraordinary on our planet – a third replicator – the consequences of which are unpredictable and possibly dangerous.

What do I mean by “third replicator”? The first replicator was the gene – the basis of biological evolution. The second was memes – the basis of cultural evolution. I believe that what we are now seeing, in a vast technological explosion, is the birth of a third evolutionary process. We are Earth’s Pandoran species, yet we are blissfully oblivious to what we have let out of the box.

The Canon: A Whirligig Tour of the Beautiful Basics of Science
by Natalie Angier.
Mariner Books, 2008.

This would be a decent overview of a broad range of basic science topics, but unfortunately the writing style ended up really putting me off. Rather than making the material more accessible, the author’s attempts at wit just confuses things and after a while gets annoying.

The man who grew a finger

Wednesday, April 30th, 2008

Quite an incredible story about a powder being developed that can regrow body parts.

“I put my finger in,” Mr Spievak says, pointing towards the propeller of a model airplane, “and that’s when I sliced my finger off.”

It took the end right off, down to the bone, about half an inch.

“We don’t know where the piece went.”

The photos of his severed finger tip are pretty graphic. You can understand why doctors said he’d lost it for good.

Today though, you wouldn’t know it. Mr Spievak, who is 69 years old, shows off his finger, and it’s all there, tissue, nerves, nail, skin, even his finger print.
