Malaysia: evolution in snails and other animals

Evolution in action at valley

KOTA KINABALU: The Kinabatangan valley is not just a haven for wildlife but is also a valuable natural laboratory of evolution, a team of Universiti Malaysia Sabah scientists found.

“If Charles Darwin had not gone to the Galápagos Islands, his theory on the origin of the species could have been born in the Kinabatangan valley itself,” said Dr Menno Schilthuizen, an associate professor at UMS Institute for Tropical Biology and Conservation.

The Lower Kinabatangan region has long been known as one of the few remaining places in Sabah teeming with wildlife such as pygmy elephants, proboscis monkeys and orang utans.

The UMS researchers have now dubbed the valley as a “veritable evolution workshop” after observing various species of land snails and the adaptations made by these creatures, as well as their predators.

Dr Schilthuizen had led the team to the Opisthostoma snails at the valley’s limestone outcrops.

The Opisthostoma snails are known for their twisted shells adorned with ribs and spines.

In the September issue of the journal Evolution, the UMS scientists reported that each hill had an Opisthostoma population with a different-looking shell.

  1. Evolution: On Sex Ratios and Social Evolution.
    When we think of modern biology, an image that does not usually
    come to mind is of an entomologist squinting over mounds of
    wasps, sorting out the males from the females, and assiduously
    tallying them up. This work requires no fancy machines, no
    chemicals, no molecular techniques. But what it does rest on is a
    theory, and such seemingly pedestrian work…

  2. Evolution: On Phenotype Conservation With Genotype Divergence.
    >From penguins to mushrooms and baobabs, the world around us
    harbors a bewildering diversity of life forms. Much of the
    evolution of this diversity is due to changes in the underlying
    genetic regulatory architecture. But what happens to such
    architecture when organisms that diverged long ago retain the
    same traits (or “phenotypes”)? Can this regulatory…
