Sharks are back in the news, and it’s in regard to their most formidable and fearsome structure—their jaws.

Zoologists recently studied the lower jaws of a number of shark species along with their lifestyle and published the results in the journal Communications Biology.¹

One of the hallmarks of good science is to formulate a cogent theory based on the physical evidence. For example, if the physical evidence (e.g. a fossilized human footprint trail or a fossil human footbone) does not agree with the time of the appearance of humans according to accepted theory, then the theory must be adjusted—no matter how significant or painful that might be.

Most all school children can recite the planets in our solar system using memory devices such as: “My Very Easy Method Just Speeds Up Names” or “My Very Educated Mother Just Served Us Noodles” (Pluto may be added at the end of each mnemonic).

The mudskipper (Boleophthalmus caeruleomaculatus) of the order Perciformes, is a fascinating fish whose evolutionary origins are quite unknown. They supposedly ‘diverged’ from other bony fish (teleosts) about 140 million years ago.

Recently, evolutionists investigated the blinking behavior of the mudskipper:

Locomotion in the human and animal world means the power to move from one place to another.
