The 2010s was a bad decade for the study of human evolution. Smithsonian Magazine recently published an article titled “These are the Decade’s Biggest Discoveries in Human Evolution.” It opens by saying: Human evolution is one of the most vibrant areas of scientific investigation. In the past decade we’ve seen many discoveries that add to our understanding of our origins. To mark the 10th anniversary of the Smithsonian’s “David H. Koch Hall of Human Origins,” here are some of the biggest discoveries in human evolution from the last 10 years. What are the big discoveries of the decade? Did they reveal new and compelling evidence that humans evolved from lower primates? Some of these big discoveries actually turn out to be instances where the evidence for human evolution weakened, and the rest…

Is Space Travel Our Destiny?

A few days ago I published the paper “The Solar System: Favored for Space Travel” in the journal BIO-Complexity. I thought it would be helpful for me to give a short summary of the paper to Evolution News readers. I was motivated to do the study after two papers were published in 2018 on the difficulty of launching rockets from super-earths. Super-earths are the most common type of planet that are being discovered around exoplanets. They are somewhat loosely defined as being larger and more massive than Earth but smaller and less massive than Uranus or Neptune. From observations, super-earths seem to transition from rocky to gas-dominated composition above 1.5 times the size of Earth.  Two Studies Together, the two studies not only showed that it is more difficult to…

Reflections on Our Ancient Past

This past October, Ola Hössjer and I published a paper, “A Single-Couple Human Origin Is Possible.” Writing in the journal BIO-Complexity, we described a model that used standard population genetics methods but refined in a new way to permit calculation of larger data arrays deeper in time. Using this model we were able to demonstrate that an initial couple could indeed give rise to the modern human population. That paper discussed the possibility of a first couple, but it did not distinguish between two alternatives. The single couple could have had a de novo origin, meaning to start from the beginning. This alternative is one most scientists choose to ignore since it does not fit with methodological naturalism (MN), the philosophical position that only “natural” explanations are allowed in science.…

Human Origins: Not a Simple Question

Photo source: Pixabay via Pexels.com. I have come to a conclusion. Perhaps if I had thought about it more carefully at first I would not be surprised. But it has only recently occurred to me that a great deal of the disturbance about evolution — yes, no, theistic, atheistic, guided, unguided, young earth, old earth, Darwinist , near-neutralist, whatever! is about human origins. Where did WE come from? Are we descended from primates or not? And what did God have to do with it? Nobody except specialist scientists would care if a little tree frog was descended from a lobe-finned fish, or was instead specially created with his special poison glands, unless it also had implications with regard to our origin. Not many would care except evolutionary biologists and entomologists…
