PREDICTS Project: Global Analysis Reveals Massive Biodiversity Losses

Thu, 21 May 2015 14:44:08 +0000

The changing climate is only one of a myriad of pressures faced by global biodiversity – we are also changing habitats and altering land-use on an unprecedented scale. The first global analysis published from the PREDICTS project reveals the striking global effect of land-use change on local biodiversity patterns, and highlights the importance of future […]

'Evolution: a can of worms'

20 February 2011

Study by GEE's Prof Max Telford et al published in Nature

Since the turn of the twentieth century, zoologists have set out from coastal marine stations at dawn to sieve peppercorn-sized worms from sea-bottom muck. These creatures, called acoels, often look like unremarkable splashes of paint when seen through a microscope. But they represent a crucial stage in animal evolution — the transition some 560 million years ago from simple anemone-like organisms to the zoo of complex creatures that populate the world today. There are about 370 species of acoel, which gets its name because it lacks a coelom — the fluid-filled body cavity that holds the internal organs in more-complex animals. Acoels also have just one hole for both eating and excreting, similar to cnidarians — a group of evolutionarily older animals containing jellyfish and sea anemones. But unlike the simpler cnidarians, which have only an inner and outer tissue layer, acoels have a third, middle tissue layer. That is the arrangement found in everything from scorpions to squids to seals, suggesting that acoels represent an intermediate form.

That hypothesis has gained considerable support in recent years, but a report published in Nature this week1 is causing scientists to rethink the storyline.  Complete article
