When Charles Darwin first published his theory of macroevolution (descent with modification from one common ancestor) in 1859, he outlined three main processes that would be the driving force of evolutionary change. To him, macroevolution was the inevitable result of random, genetic mutations that produce a change in the species that is preserved by natural …
In our world today where it seems change is the only constant thing or maybe where it seems things are spinning out of control, there is still the constancy and order of the universe. While it’s probably not something that is given much thought, no matter what craziness happens in the world, gravity is still …
Since 2021, Greek letters are not just for identifying college fraternities or sororities but for identifying variants of COVD-19. Alpha, Beta, Delta, and now Omicron variants are studied and compared on the severity of symptoms, how quickly each variant may spread, and its resistance to treatments. Quite often when these variants are being discussed, the …

For centuries there has appeared at first glance to be a conflict between science and religion. Do the planets revolve around the earth or the sun? Is the earth flat or is it a sphere? Do animals reproduce according to their kind or can they evolve into different kinds? However, when we take a closer …
One of my least favorite doctor’s visits each year is to the optometrist. I would much prefer to have my teeth cleaned at the dentist (actually I love having my teeth cleaned at the dentist) than go to the eye doctor. And I’m not entirely sure why, other than my eye sight is always getting …
There either is a God or there is not a God. There is no in between. There is not a kind-of, sort-of, maybe God. But how could we ever know if this God does or does not exist? Atheists would say there is no God. Theists would say there is a God. Agnostics would say …
If you have ever spent any time in the south during the summer, you quickly learn about three things: humidity, mosquitoes, and ticks. While I am somehow the bug repellant for everyone else (since I’m always the first and worst to be bitten by the mosquitoes), it’s the ticks that really make my skin crawl. …
Last week I was visiting with my dad at his cabin in the mountains. He has been having this ongoing battle with a pileated woodpecker that loves perching on his window screens. My dad has hung all kinds of crazy junk in the windows and fake owls by the house to try to discourage this …
