0:00.0 | Welcome to ID the Future, a podcast about intelligent design and evolution. |
0:13.7 | Welcome to ID the Future. I'm Sarah Chaffee, and I'm pleased to have back on the show today |
0:19.3 | German paleontologist Gunter Beckley for an encore interview. |
0:23.3 | We've been talking about the new anthology from Crossway, Theistic Evolution, a scientific, philosophical, and theological critique. |
0:31.5 | In a previous conversation, we were discussing the chapter Beckley co-authored on the fossil record and the theory of common descent. |
0:39.3 | But the topic is a rich field, with a lot more to explore. |
0:44.3 | When we left off, Dr. Beckley had noted that there were many instances in the fossil record of a dramatic and abrupt appearance of new animal forms, |
0:53.3 | not at all what one would expect from a |
0:55.7 | gradual evolutionary process of small mutations and slow diversification of life. |
1:02.3 | What I want to ask you next, Dr. Beckley, is this. |
1:06.0 | You mentioned that there are close to 20 big radiations in the fossil record, moments where in a geologically |
1:12.5 | brief window, many new animal forms seem to appear out of nowhere. Is there one particular |
1:19.4 | radiation that stands out to you that you would like to share with our listeners? |
1:25.1 | There are several ones. So I would drop the Cambrian explosion because that is |
1:31.1 | the most well known and I think more interesting is to hear about some of the other events. |
1:41.3 | So one event that I briefly mentioned is this great Ordovician biodiversity |
1:45.9 | event, which happened in the geological era of the Ordovician about 470 million years ago. |
1:55.3 | And there you had an explosive radiation origin of all those different families of marine invertebrate organisms, |
2:05.4 | more than 300 families appear suddenly without precursors in the older layers. |
2:14.6 | So that would be similar to the Cambrian explosion, but a totally different event, but it has |
2:21.3 | been called in the popular press live second Big Bang, even though it is much less well known |
2:28.9 | by the general public. There is a preceding event to the Cambrian explosion, the so-called Avalon explosion, |
