Even more ancient hominins from Europe

Two recently published articles caught my eye today. One reports on the analysis of Initial Upper Palaeolithic human remains from Bulgaria that showed recent Neanderthal ancestry [1], the other reports on the analysis of a skull from the Czech Republic which showed the individual to have been one of the earliest people in Europe following the expansion out of Africa [2]. Dating between 42,000 to at least 45,000 years, it is worth noting that we have here yet more evidence for the antiquity of modern humans far outstripping the ~6000 years limit given by a fundamentalist interpretation of the Bible.

The Case of the Missing Isotopes - The Ultimate Proof of an Ancient Earth

Given that the Earth is around 4.5 billion years old, we would not expect to find any radioactive isotopes with short half-lives in the crust of the Earth as they would have long since decayed away. Conversely, if the Earth really was six thousand years old, then we'd expect to find these short-lived radioactive isotopes as insufficient time would have passed for them to have decayed away. When we examine the Earth's crust to look for short-lived radioactive isotopes, apart from those naturally made, we find no short-lived isotopes, just what we'd expect if the Earth was ancient.
