For those without his specialist expertise, forget everything you thought you knew about Spring and Summer, Autumn and Winter. Darwin has 7 seasons, as the Larrakia People tell us, and the World Solar Challenge begins towards the end of Dalirrgang (the “Build Up” – click image above for multimedia tutorial). Dalirrgang is a kind of overture to the rainy season (the “Wet”). Traditionally, Dalirrgang is the time to hunt the Magpie goose (photo by Djambalawa below).
Long-term weather forecasts suggest that the World Solar Challenge this year might in fact begin on a partly sunny day, with a little rain, but that’s very uncertain, this far ahead.
This well-written book provides an excellent explanation for how a toolkit of genes like the Hox genes (see image below) control embryonic development in animals. The discovery of these genes shows that fruit flies, starfish, and people are more closely related than was once believed.
These genes work by producing proteins which in turn control the expression of other genes, in what is effectively a kind of computer program that can be visualised (and Endless Forms Most Beautiful contains several lovely colour plates which confirm this).
Carroll concludes with a plea for teaching more evolutionary biology in schools. Personally, I think a greater priority would be an increased emphasis on teaching ecology, given the serious consequences which human activities (even well-meaning ones) can have for the planet. However, that quibble does not stop me from recommending this book to anyone who has not read it yet.
Endless Forms Most Beautiful by Sean B. Carroll: 3½ stars
