1. 1. The Ediacaran Diversification of Organic-walled Microbiota : Ocean Life 600 Million Years Ago

   Författare :Sebastian Willman; Małgorzata Moczydłowska-Vidal; John Peel; Shuhai Xiao; Uppsala universitet; []
   Nyckelord :Earth sciences; acritarchs; Ediacaran; Australia; biostratigraphy; microfossils; Geovetenskap;

   Sammanfattning : The only direct evidence of past life is provided by fossils. Fossils tell us about the evolution of life on Earth and they give us clues concerning ancient environments. The Ediacaran Period (roughly 635-542 million years ago) is characterised by the appearance and diversification of various microbiota and also the diversification of metazoans. LÄS MER

   Sammanfattning : The emergence and radiation of metazoan body plans around the Precambrian/Cambrian boundary, some 500-600 million years ago, seems to be concordant with the appearance and diversification of preservable hard parts. Several Precambrian soft-bodied, multicellular organisms most likely represent stem-group bilaterians, but their fossil record is rather sparse. LÄS MER

   Sammanfattning : Asymmetrical conflicts and power relations between extractive industries and Indigenous groups often have devastating consequences for Indigenous peoples. Many Indigenous groups are struggling to maintain their lands as Indigenous perspectives on connection to Country are frequently undervalued or dismissed in favour of extractivist ideologies.

5. 4. Molecular Profiling of the Population Dynamics : Foundation and Expansion of an Archaic Domesticate

   Författare :Arman Ardalan; Peter Savolainen; Love Dalén; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dog; wolf; dingo; mtDNA; NRY; SNP; Madagascar; Australia; domestication;

   Sammanfattning : "An ‘exponential growth of science’ throughout modern history has been frequently boasted by numerous narcissistic accounts of ‘modern humanity.’ Nonetheless, ‘modern science’ seems to have overwhelmingly compromised on its original promises by fitting into an ‘industrial scheme.

7. 5. Biostratigraphy and Systematics of Cambrian Small Shelly Fossils from East Antarctica and South Australia

   Författare :Thomas M. Claybourn; Lars E. Holmer; Glenn A. Brock; Christian B. Skovsted; Graham Budd; David Harper; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cambrian; Biostratigraphy; Systematics; East Antarctica; Small Shelly Fossils;

   Sammanfattning : The remote lower Cambrian Byrd group of sedimentary rocks from East Antarctica has been studied intermittently since its discovery over a century ago. Previous insights into the trilobites and archaeocyaths indicated a close correlation to the sedimentary sequences of South Australia. LÄS MER
