Mission Galapagos

Liz Bonnin in the superb BBC 3-part series Galapagos, a beautiful and informative documentary

Mission Galapagos was a high-tech science expedition to examine what the Galapagos Islands can tell us about evolution and the effect of climate change on wildlife.

The islands, located in the Pacific about 1000km west of Ecuador, are not a place for Creationists to think about (doing so would fry their brains).

One of many things we learn is how the islands were formed (and are still being formed), how long this has taken, and why they are so different from each other.

It turns out that the islands sit on the Nazca tectonic plate that acts like a conveyor belt, trundling very slowly eastwards (at around 58km per million years), passing over a magma hot-spot below. This hot-spot constantly generates new volcanos as the plate moves eastwards, which rise above sea level to become new islands. Eventually the volcanic islands leave the hot-spot and cool so that they develop lush vegetation, and finally disappear underwater again (as the plate slides downward beneath the South America Plate) to become submerged mountains.

The Mission Galapagos science team visit one of the most awesome and dangerous dive spots in the world...

...and where hammerhead sharks (globally endangered) congregate in vast numbers for a mating ritual

Among many other animals investigated was the astonishing marine iguana, living above and below water,
which has evolved so that the same animal can shorten its length in hard times

There was much to enjoy in this documentary, whether above ground, underground or underwater. Some people, sadly, may never get to see it. American networks were very reluctant to show the final episode of Sir David Attenborough's Frozen Planet, because it showed "controversial" evidence of the effect of climate change at the Poles. What Bible Belt America and Trump America will make of Mission Galapagos, should they get to see it, is anyone's guess.

It is not only in America that Science, Technology, Engineering and Maths (STEM) is under threat. There have recently been massive worldwide “Marches for Science”, protesting against “a global political assault on facts”. Anyone who doubts the significance of this is invited to peruse my Trump Diaries.

Liz Bonnin is one of my personal heroes in what is genuinely a fight against the forces of darkness. Her scientific background (she is a biochemist and Wild Animal Biologist, among other things) and her personality make her a very effective ambassador for STEM.

In the UK, as elsewhere, it was realized some time ago that disrespect for STEM would cost the country dear if not reversed. One of the first shots in achieving that was the successful BBC Series Bang Goes The Theory, where I first saw Liz in action.

Now young people (and especially girls) are being actively encouraged to take an interest in STEM.

Sadly, the USA is cursed with an anti-science (and anti-reality) President who seems bent on undermining the US's science and technology base, with untold consequences - but that's another story.
