Dinosaurs not killed off by asteroid impact?

The theory that the dinosaurs were killed off by the Chicxulub meteor about 65 million years ago may be wrong! I found the article in Time, but Gerta Keller of Princetons Chicxulub page has more details. The findings are apparently not new having been presented in France in 2003 after 10 years of fieldwork. Not sure why Time picked up the story recently unless the findings are only being published now in the Journal of the Geological Society that she and another researcher were able to find just as many species in the 30 ft layer of soil above the infamous iridium layer laid down by the asteroid impact as beneath it at several sites in Mexico suggesting that the impact didn’t kill off any species at all. The mass die off appears to occur above this 30 ft layer, so their research suggests whatever killed off the dinosaurs happened about 300,000 years after the asteroid hit.

Humans related to Sharks

Recent genetic studies suggest that Humans and Sharks shared a common ancestor 450 million years ago. At first this might seem unlikely, but humans and sharks do share some traits that aren’t found in fishes – they copulate (internal fertilization), and they bear live young. According to the ABC article, we also share some DNA having to do with our sperm and immune system

How Good are Young Earth Claims by Creationists?

Be aware of the most popular Creationist arguments for a Young Earth which many of them see as their best hope in their holy crusade against evolution (and reason). Many of their claims sound like they are based in science, but they don’t stand up to even the most casual scrutiny.

If you have some time, poke through Dave Matson’s posting:
How Good Are Those Young-Earth Arguments? (1995) A comprehensive, point-by-point refutation young-Earth arguments and other creationist claims made by Dr. Kent Hovind (“young Earth creationist and dinosaur hunter”) in the Hovind-Patterson debate.

Dover Trial Closing Words

For those of you who followed the Dover Trial in PA closely, you still may have missed this little tid-bit. Wikipedia states that ‘Kitzmiller, et al. v. Dover Area School District, et al. is the first direct challenge brought in United States federal courts against a public school district that has tried to mandate the teaching of intelligent design as an alternative to evolution.’ The parents of several students brought suit against the school board after they decided to mandate that Biology teachers read a prepared statement to the effect that evolution is ‘just a theory’ and that an alternative, in ‘Intelligent Design’ (ID) exists and that books on the theory were placed in the library.
