Humanly Possible

Humans are uniquely capable of creativity, gamesmanship, planning, abstraction, ceremony, language, and on and on. In all these respects, we far surpass what a mere animal can do. Here we gather but a sampling of the effusion of human creativity and striving. Photos from Unsplash

Human Uniqueness Continued

“In terms of what makes us human, it’s not the things that are the same, it’s the things that are different that matter.” Jonathan Marks For something light-hearted: Imaginative FictionSupposed the table’s turned,And she was in my place,Then she’d be up late typing And I’d stare off in space.I think I’d like the next day off To vegitate and doze.But I ask, dear readers, how much sense expect–It’s vagrant typing that makes a chimpanzee’s prose.(That is, before she defecates on the typewriter or throws it across the room.)

On Being Human — A Reflection

Evolutionary biologist David Barash is a man on a mission. He wants to make sure that we all know we are only human, and that means we are only animal. We share DNA, mitochondria, organelles, our very flesh with animals, and so are animals too. We might as well give up any hope of being sons of God. That story in the Bible that we were created specially is just a story according to Barash, and a dangerous one at that. I heard him give an interview on the Seattle NPR station. He has a winsome way of speaking. He makes a point of telling the story of our common evolutionary origin to his classes at the University of Washington Read More ›

A Single-Couple Human Origin is Possible

Abstract: The problem of inferring history from genetic data is complex and underdetermined; there are many possible scenarios that would explain the same data. It can be made more tractable by making reasonable simplifications to the model, but it is continually important to remember what has been demonstrated and what is merely a parsimonious working assumption. In this paper we have chosen to model the demographic ancestry of humanity using the simplest of assumptions, with a homogeneous population whose size can vary over time. All other assumptions such as the mutation rates were standard, and no natural selection was in operation. Using a previously published backwards simulation method and some newly developed and faster algorithms, we run our single-couple origin Read More ›

New BIO-Complexity Paper: We Could Have Come from Two

If you asked pretty much any population geneticist about human origins they would say, “All the evidence says the effective population size has never been below several thousand.” That’s certainly what Dennis Venema thought, and said most emphatically. Read More ›
