Massive Australian Precambrian/Cambrian Impact Structure Massive Australian Precambrian/Cambrian Impact Structure The Massive Australian Precambrian/Cambrian Impact Structure also known as MAPCIS is a proposed impact structure based upon arguments presented by Daniel P. Connelly at Geological Society of America meetings. Its center is located approximately equidistant between Uluru (Ayers Rock) and Mount Conner in Australia's Northern Territory. The structure is approximately in diameter. However, a hypothetical outermost ring in diameter is claimed to be the result of undefined far field stresses. Connelly argues that the age of this hypothetical impact is approximately 545 mya which puts it just before the Cambrian explosion (542 mya) of the
Genetic sexual attraction that unrelated people are less attracted to those genetically similar to them. However, in mice, this lack of attraction can be reversed by adoption. Whilst it has been documented that sexual attraction can occur between related individuals in some cases, it is not clear that calling this attraction GSA is appropriate. Critics of the hypothesis have called it pseudoscience. Amanda Marcotte of "Salon" has stated that the term is nothing but an attempt at sounding scientific while trying to minimize the taboo of incest. She also expressed that many news outlets have handled reports of the subject poorly by repeating
