I owe the following example of evolutionary adaptation to the always amazing evolutionary and developmental biologist Dr. Sean B. Carroll, from his lecture “Making of the Fittest” for the Darwin College – Darwin Lecture Series, available at iTunes U (I highly recommend everyone give it a listen).

Imagine that you are a fish – exothermic and [...]

There’s one particular event of every summer in the South that I always await with great anticipation: the emergence of the millions of annual Dog Day cicadas (Tibicen canicularis).
It’s not just the event itself that I love. The cicadas are certainly wonders in themselves; but for me, they are more than just insects of the [...]

Earlier this week, thanks to the wonderful science & nature Twitter community, I followed a link from someone now forgotten to an article entitled “7 Symbiotic Wonders of the Aerial World.”
Therein, in symbiotic relationship number one, sat a photograph that I found utterly astonishing:
According to the WebEcoist website which published this list of “symbiotic wonders.”
“It [...]

Most biologists at one time or another in their training have learned of the 19th century theory expounded upon by Ernst Haeckel called “Recapitulation Theory“.
The theory’s thesis: “Ontogeny recapitulates phylogeny.” Don’t worry – it’s not as complicated as the biological jargon might imply.
The idea boils down to a simple one – one that seemed to [...]

“In the gloom it came along the branches towards me, its round, hypnotic eyes blazing, its spoon-like ears turning to and fro like radar dishes, its white whiskers twitching and moving like sensors; its black hands, with their thin fingers, the third seeming terribly elongated, tapping delicately on the branches as it moved along.”

I’ve decided to start a weekly series highlighting interesting, strange, or just plain cool evolutionary adaptations. If any of you have suggestions for adaptations that you find particularly interesting, I would be happy to include them.
I’m gonna start off with a species that is dear to my heart, the Timber Rattlesnake (Crotalus horridus). Back in [...]
