From ScienceDaily: Pseudooides fossils have a segmented middle like the embryos of segmented animals, such as insects, inspiring grand theories on how complex segmented animals may have evolved. A team of paleontologists from the University of Bristol’s School of Earth Sciences and Peking University have now peered inside the Pseudooides embryos using X-rays and found features that link them to the adult stages of another fossil group. It turns out that these adult stages were right under the scientists’ noses all along: they have been found long ago in the same rocks as Pseudooides. Surprisingly, these long-lost family members are not complex segmented animals at all, but ancestors of modern jellyfish. Paper. (public access) – Baichuan Duan, Xi-Ping Dong, Luis Read More ›

From ScienceDaily: Now scientists have reviewed all the evidence pointing towards an animal identity of the Weng’an fossils. Their findings have revealed that none of the characteristics previously used to define the fossils as animals are actually unique to animals alone, opening up the possibility for alternative identifications. Professor Philip Donoghue, another Bristol co-author, added: “Many proponents of animal affinity have argued that the Y-shaped junctions between the cells in the fossils are an important animal character, but this a feature common to many multicellular groups, including algae, that are very distant relatives of animals.” Dr Cunningham added: “It could be that the fossils belong to other groups, such as algae, and these possibilities need to be investigated carefully.” Despite Read More ›

In recent days, the issue of an infinite temporal past as a step by step causal succession has come up at UD. For, it seems the evolutionary materialist faces the unwelcome choice of a cosmos from a true nothing — non-being or else an actually completed infinite past succession of finite causal steps. Durston: >>To  avoid  the  theological  and  philosophical  implications  of  a  beginning  for the  universe,  some  naturalists  such  as  Sean  Carroll  suggest  that  all  we  need  to  do  is  build  a  successful  mathematical  model  of  the  universe  where  time  t runs  from  minus  infinity  to  positive  infinity. Although  there  is  no  problem  in  having  t run  from  minus  infinity  to  plus  infinity with  a  mathematical  model,  the real Read More ›
