A tidal wave of genomic information came ashore this week in the form of 45 new genome sequences of birds. In a series of papers released in Science hundreds of researches combine to analyze the hundreds of billions of pieces of genetic code of representatives of all the major groups of birds. Prior to this only […]
There is a very recent form of fossil hunting that I have gotten to partake in to some small extent, and I can do it while sitting in front of a computer screen! With some computer skills and some knowledge of animal genomes it isn’t difficult to join this hunt for fossils inside the genome of living organisms.
Last week I pointed out that the Bible provides no support for Ken Ham’s contention that massive numbers of species have formed following their departure from Noah’s ark 4500 years ago (YEC Biblical Evolution: I Have A Book That Says Otherwise). Now I’m following up with “observational” evidence from DNA sequences to test whether the […]
Last week Ken Ham promoted a biblical evolution model to explain the diversity of life on Earth. I have a book before me that provides compelling evidence that this model of evolution is wrong. That book is the Bible. For those that follow the creation literature nothing that Ken Ham said last week in his […]
Cancers are cells that have forgotten who they are supposed to be. They become independent brats in the body, hogging resources and dividing uncontrollably. The problem, from the cancers perspective of course, is that being a spoiled brat may bring short-term rewards, like lots of progeny and freedom from having to behave like the cell […]
There are about 10,000 species of birds alive today. Almost 200 additional species have gone extinct since the year 1500 and there are innumerable fossil species of birds in the geological column. One of the persistent challenges for modern young earth creationists is how to fit the diversity of life on the Noah’s ark. Answers […]
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 […]
As we saw in the last installment of this series, When is a Horse a Horse?, horse species today appear to represent divergent genetic units that naturally do not interbreed on a regular basis. Therefore each of these lineages of horses is acting like a species as defined by the biological species concept. This raises the […]
Creationists are becoming more and more likely to view the origin of horse species and other large groups of similar species as the result as descent from a common ancestor albeit via mechanisms and at rates which may not be recognizable to evolutionary biologists. But where does does variation in a kind end and a new kind begin?
