Remember Evolutionary Psychology? The theory? It’s over.

Does your back yard slope up, away from your house, or does it slope down? The likelihood that your yard slopes one way or the other … statistically … depends in large part on what region you live in. (Here I’ll be speaking mainly of the US, but the principle applies broadly.) If you live…

Falsehood: Humans evolved from apes

Is it a Falsehood that Humans Evolve from Apes? How about this one: Is it a Falsehood that Humans did NOT evolve from Apes???? Yes and no. Humans descend from a population of primates from which other apes also descended (minimally the two species of living chimps) and which was part of the panoply of…

The story, complete with extinct elephant-like creatures and a real Sherlock Holmes science theme can be read, along with some great images, at A Neotropical Savanna:…

Such are the words uttered by a young physical anthropologist in response to Sir Edmund Hillary’s request that he join the search for Yeti on the fridgid snow clad slopes of Mount Everest.

I had mentioned earlier that the volcanoes of the Virugna region in the Western Rift Valley (as well as other highland spots) have often been islands of rain forest separated from each other by different habitats, including grasslands and wooded savannas. this has produced an island effect that has been a laboratory for evolution, and…

Minnesota moose experts generally agree that global warming is forcing the southern edge of the distribution of the moose northward into Canada, threatening this important US population of this ginormous deer species. Global warming denialists insist that this is the moose’s fault, and has nothing to do with global warming. This is the first of…

We have had a cool summer here in Minnesota, and this has brought out the miscreants who for their own reasons do not want to get on board with the simple, well demonstrated scientific fact that global temperatures have risen, that we humans are the primary cause, and that this climate change has negative consequences.
