sequence stratigraphy

Inside science

I'm not sure why sequence stratigraphy is being questioned but anything that challenges the neat layer cake method is worth taking note of. The link was sent in by Robert Farrar, http://crev.info/2016/03/is-geology-in-a-scientific-revolution/ .., and one can quickly answer the headline by saying, no. It is an intriguing head line and the suggestion is that a paradigm shift might be in the offing. Sequence stratigraphy is an important feature of geological theory – the time sequence of strata between nonconformities. Now, if nonconformity was to read catastrophe then a paradigm shift in sequence stratigraphy between catastrophes would be something to get excited about – but not sure that is correct. Catastrophes can be localised affairs so a local switch in sequence stratigraphy is to be expected – although not always acknowledged. Access to the full article is necessary – rather than to the abstract. The paper is published in the journal Geology (March 2016) and sparked the expectation of the author at crev.info who himself asks for input from Creationist geologists on the issue. However, rather than the article abstract it seems the editorial is what caught the attention of the author as Thomas Kuhn is invoked. It asks if sequence stratigraphy has been challenged but in the end puts the issue back in the box. What is surprising is the editorial comment seems to show extraordinary openness for a science journal (according to the author). Problems are usually glossed over or simply ignored in the run of the mill article but here the reader is being challenged to think outside the paradigm.

At http://crev.info/2015/03/body-diversity-threatens-to-undermine-paleoanth… … is worth looking at as well. Here the red herring appears to be that humans come in all shapes and sizes and you only have to look around you when you go shopping or when you are sitting on a park bench and people are walking past. The argument here is that early forms of humanity such as Neanderthals and Homo Erectus are defined in part by body size and shape – which may be totally wrong. This was brought home to anthropologists themselves not so long ago when a cache of bones in the Transcaucasus region revealed a hotch potch of early humans – and lots of different shapes and bone density etc.

At http://crev.info/2016/02/neanderthal-concept-has-imploded/ … we have somebody at last bringing a bit of common sense into the issue of human relations with Neanderthals. They are us and we are them. Can't say it any better.
