Misunderstood Marine Life # 7 – The Living Fossils

evolution, History of Science, Natural Science, Ocean of Pseudoscience Week, ScienceOctober 3, 2011

Horseshoe Crabs, Coelacanths, Seven-gilled sharks, hagfish. Throughout the oceans there are creatures whose primitive bodies hearken back to earlier days in our evolutionary history. They possess basal characteristics that are more akin to those of the ancestors of our contemporary phyla. Because we can look into these organisms and learn something about our own deep past, we […]

In sexual selection and thermoregulation, bigger is better, at least for fiddler crabs

biology, ecology, evolution, marine science, Natural Science, ScienceSeptember 21, 2011

Imagine yourself a fiddler crab. For this exercise, imagine yourself a male fiddler crab. Are you with me? Great. Check out your right claw, it’s a sleek, slender machine, perfect for picking through the sand as you sift out bacteria and other microorganisms for food. It also makes a handy shovel for digging nice deep […]

Apparently this happening also involves some high-falutin’ muckity-muck. I had managed to avoid just about everything about this event, until my shields were ultimately breached by an unlikely saboteur. The scientific […]

Conservation and the Concept of Species in a Biodiversity Crisis (Part 1)

biology, Conservation, ecology, evolution, Natural Science, ScienceJanuary 24, 2011

In The Mass Extinction of Scientists Who Study Species, Dr. Craig McClain argues that we are loosing a fundamental unit of biological science – the Taxonomist. He’s right, of course. Taxonomy is a shrinking field. Entire phyla sit, unstudied, as the expertise necessary to understand them retires and expires. With few to train the next […]

A recipe for the evolution of smaller fish stocks?

Chemistry of the Great Big Blue, evolution, fisheries, Natural Science, Science, toxicologyNovember 11, 2010

Overfishing is most often implicated as the cause of decreasing fish stocks and that makes a lot of logical sense if you’ve ever seen a large commercial trawler unload its catch. But there very well might be another force at work in the precipitous decline in fish stocks worldwide: pollution. The basic premise is that […]
