The Amazon basin isn’t all just a lush tropical forest. In large portions of western Amazonia wet seasonally-flooded grasslands, not trees, are the norm. The upper branches of the Amazon River wind themselves across massive flood plains like snakes writhing across a sandy surface. One feature of these nearly featureless flat plains that has puzzled […]
What museum can you go to where you can see real dinosaur bones, you don’t pay any fees, you can touch all the exhibits and there are no security cameras watching your every move (at least I don’t think there are:-)? The answer is The Mill Canyon Dinosaur Trail near Moab, Utah. This outdoor “museum” […]
A few weeks ago there was a report of an entire horse genome that was sequenced from a fragment of a horse preserved in permafrost sediments buried in the Yukon region in Alaska. The fossil was estimated to be 500 thousand years or more old and thus this represented one the oldest DNA sequences yet […]
The site of one of the largest volcanic eruptions in earth’s history, the effects of the Toba Super Eruption have been of considerable interest to archaeologists and anthropologists because of its potential impacts on past human populations. New research exploring the Toba Super Eruption (Sumatra) has been published since I explored the implications of the […]
Remember the meteor that exploded over Russia earlier this year? A 50 foot diameter object exploded 14 miles above the surface of the earth and created a shock wave that injured 1500 people and damaged more than 7000 buildings. Despite the drama, the lasting effects on the earth were minimal and only small pieces of the meteorite made it to the surface of the earth.
A recently published study is making news the last couple of days. It regards evidence obtained from remains of preserved bones of human scavenging and/or hunting practices. The site of the dig is a hillside in southern Kenya where, in less than an acre, more than 3700 fossils and more than 2000 artifacts have been recovered […]
In my class yesterday I reviewed a paper selected by my students that explored the sweet tasting abilities of bats. We learned that most, but not all, bats can taste sugar like other mammals. I did not know much about mammalian taste receptors (that is one problems with letting students pick the topics!) and I […]
Last time I looked at horses I noted there were differing opinions about the significance of the fossil record or horses and how it should be interpreted. Among creationists, Wood and associates clearly see the horse fossil record differently than Sarfati and Molen. So what are the later not seeing that Wood et al. […]
