Antibiotic Overuse May Increase Superbug Evolution Rate Multiple drug-resistant Staphylococcus aureus bacteria seen under an electron microscope. Photo: CDC By flooding our environment with antibiotics, people may alter a little-appreciated but profound aspect of bacterial evolution: the very pace at which it occurs. Bacteria may evolve more rapidly and more radically than just a few decades ago. This proposition is still a hypothesis, but it’s an intriguing one. While drug resistance is a well-known consequence of antibiotic use, a global acceleration of bacterial mutability could make drug resistance more common and shape pathogens in unpredictable ways.

Ishango bone The Ishango bone is a bone tool, dated to the Upper Paleolithic era. It is a dark brown length of bone, the fibula of a baboon,[1] with a sharp piece of quartz affixed to one end, perhaps for engraving. It was first thought to be a tally stick, as it has a series of what has been interpreted as tally marks carved in three columns running the length of the tool, but some scientists have suggested that the groupings of notches indicate a mathematical understanding that goes beyond counting. Edwards v. Aguillard [This is the text of the 1987 United States Supreme Court decision striking down a Louisiana law that required if evolution is taught in public schools then creationism must also be taught. This 7-2 decision ended any prospect of public schools in the United States being legally forced to teach explicate creationism. One consequence of this case was that some antievolutionists choose to use the term "intelligent design" instead of "creationism."]

The pace of evolution The pace of evolution Does evolution occur in rapid bursts or gradually? This question is difficult to answer because we can't replay the past with a stopwatch in hand. However, we can try to figure out what patterns we'd expect to observe in the fossil record if evolution did happen in bursts, or if evolution happened gradually. Then we can check these predictions against what we observe. What should we observe in the fossil record if evolution is slow and steady? The 5 Strangest Things Evolution Left in Your Body If you don't believe in evolution, you have to spend a lot of time wondering about the useless shit the creator threw into our bodies. Why don't our wisdom teeth fit in our heads? Why do we need an appendix? The answer is that evolution is a sloppy and haphazard process. Take a close look at your body and you'll see some of the leftover junk.
