Sea Urchin Teeth Are Designed to Grind Stone

by Brian Thomas, M.S.*

Sea urchins are spiny marine animals. Some of them like to hide in holes that they dig out of limestone in the ocean floor, using teeth that are ground down and yet remain sharp. What makes these teeth so special that they can drill through rock and not go blunt?...

Too much materialism in your excerpt for me.

Fascinating. It doesn’t push me in the direction of intelligent design over natural selection but things like this always increase my awe and respect for life.

Mr. Thomas again masters the great leap of taking a singular supposed example and making great inferences where none exist. Sea urchins are very niche specific and have no competition in that niche. They had no selective pressure to change their feeding apparatus. However, if Brian had bothered to go any farther than a cursory glance at one article he would have noted that there are over 6000 species of urchins. Fundamentally, sea urchins represent a well diversified phylogenetic tree.

And yet no transitionals between non-sea urchins and sea urchins...just as biblical creation predicts.

“What makes these teeth so special that they can drill through rock “

Answer ... The animal’s teeth must be harder than limestone, just as diamonds are harder than glass.

Consider aslo that limestone is a sedimentary rock ... the product of sediment collecting on tue bottom of some ancient lake, river or ocean; and that limestone is a far less hard substance than granite, a metamorphic rock.

Actually, I believe that sea-urchins have one of the best transitional fossil records available and there is also a good genetic mapping of evolution backwards to sea stars, sand dollars, and simpler and simpler organisms whose relatives still exist today.

It's good to be a sea urchin.

Didn't the Coasters have a song about this?

Cause I've been sea-urchin, oh yeah, sea-urchin,
My goodness, sea-urchin every which a-way. Yeah. Yeah.
But I'm like the Northwest Mountie,
You know I'll bring her in some day.
 Gonna find her

That’s my point. The Evos don’t have transitionals. All they have are separate and distinct species that their world view compells them to **believe** are transitionals. Yet more proof that goo-to-you evolution is based on faith, not science.
