Recently the U.S. Supreme court made decisions that equate "gender identity" with "sex (gender)" in civil rights law. This is not only unbiblical, but unscientific. Our DNA governs our gender – whether we are male or female – with XY or XX chromosomes. This is a biological, scientific fact. In contrast, "gender identity" is governed… Continue reading “Gender Identity” Is Unscientific

A puma. Even though this cat is big, it is not considered a big cat. Do you know what is the big cat that lives in the United States? Just so you know, I am not referring to the puma. The puma, also called the mountain lion or cougar, is indeed a big cat if… Continue reading The Big Cat in the United States

Hagfish at the Oklahoma Aquarium. It is difficult to see the individual fish. The small blue arrow is pointing at the head of one hagfish. The mouth is ringed by barbels, which look a bit like small tentacles. These were used for sensing their environments. Recently, my family visited the Oklahoma Aquarium in Jenks, Oklahoma.… Continue reading The Jawless Hagfish

Can you tell what it is? If not, that is okay. When it was first described in 1899, Helicoprion… Continue reading The Tooth Whorl of a Strange Shark

A radiometer in action. The radiometer is the bulb on the right. Note that the bulb is sealed: nothing material, including air, can get into the bulb. That means that the only thing that can get into the bulb and cause the fins to spin is light. You may be aware that light behaves both… Continue reading Light as a Particle

A rose? What does this have to do with predators? It turns out that roses and predators may be two types of organisms that were modified at the time of the Fall. We have noted that some carnivores, such as bears and dogs, have herbivorous or omnivorous members of their families, and thus it is… Continue reading The Origin of Predators, Part 4

The massasauga, also called the pygmy rattlesnake. Pit vipers, like this guy here, are specialized for killing small animals. In the last post, we considered the possibility that carnivores began as animals that ate invertebrates. An example of an insectivore that is closely related to carnivores is the sloth bear. The bears provide another example… Continue reading The Origin of Predators: Part 3
