In science, we should more openly discuss what has been published, but the reality is that as a professional scientist you hardly can afford it (for many reasons).Das Grimmhttps://www.blogger.com/profile/13213125622809796109noreply@blogger.comtag:blogger.com,1999:blog-1592175903857348966.post-49222630134566643162018-08-15T10:08:52.481+02:002018-08-15T10:08:52.481+02:00This has been a highly informative read.

I'm in the process of writing my application for a PhD (just finished my masters in Taxonomy and Biodiversity), and I cannot stress enough the importance of reading such honest perspectives on scientific articles, especially ones that have been published in reputed journals. For a rookie like me, the insights this article has provided is indeed a goldmine.

Discord between molecular clock and purely fossil-based interpretations of angiosperm diversification may be a consequence of false precision on both sides." And "We reject a post-Jurassic origin of angiosperms, supporting the notion of a cryptic early history of angiosperms, but this history may be as much as 121 Myr, or as little as 23 Myr. These conclusions remain compatible with palaeobotanical evidence and a more general KTR [Cretaceous Terrestrial Revolution] in which major groups of angiosperms diverged later within the Cretaceous, alongside the diversification of pollinators, herbivores and their predators."<br />J Barba-Montaya, M dos Reis, H Schneider, PCJ Donoghue & Yang Z.

It'...A highly informative text and fun to read! It's also an important text from a science-sociological point of view. I think Grimm is right that paleobotanists who are experts on early angiosperm fossils would gain the most by collaborating with experts in molecular-clock dating because, as he says, who but not them would know about the best fossils and their most appropriate placements. <br />Susanne Renner, 7 January 2018Anonymoushttps://www.blogger.com/profile/14191044014056785608noreply@blogger.com
