Midnight chimes on New Year’s eve on the steps of the imposing Girona cathedral, and crowds repeat what has been a 2,000 year old tradition. View in LinkedIn

THE DOMINANT PLANT SPECIES. “It has become traditional to open a discussion of angiosperm origins by quoting Charles Darwin who described the problem as an abominable mystery. But what is so mysterious and so abominable about angiosperm origins is that, after 140 years of research and profuse publication, there still is no light at the end of the tunnel?” https://lnkd.in/dq9cE6j2 View in LinkedIn

EO Wilson. “Ants are possibly as close as we will ever see to what higher social organization might look like on another planet. They communicate almost entirely by smell and taste. They have extremely complicated societies.” https://youtu.be/RcGeewpiCr4 View in LinkedIn

PATCHY DATA. “The database of geomagnetic paleopoles thought to be of Precambrian age is ambiguous and undersampled. Age of magnetization is the most critical and least known parameter and only selectivity of data has enabled consistency with popular conclusions.” https://www.sciencedirect.com/science/article/pii/S0012825219302636?via=ihub View in LinkedIn

TECTONIC SUPERCONTINENTS. “Illustrations have been devised of analogous plate-tectonic activity in the form of disruption and reassembly of hypothetical successive but similar Precambrian supercontinents Columbia and Rodinia.” https://www.sciencedirect.com/science/article/pii/S0012825219302636?via=ihub View in LinkedIn

THE ORIGINS OF THE MYTH. “Because 1970s conjectures that whole-mantle convection and plate tectonics operated throughout most of Earth history dominate paleodynamic literature, studies of the magnetization of Precambrian rocks have mostly interpreted data in these terms.” https://www.sciencedirect.com/science/article/pii/S0012825219302636?via=ihub View in LinkedIn

TECTONIC MINDSET. “Phanerozoic lithosphere motions are well documented by paleomagnetic recordings of plate-tectonic sundering of supercontinent Pangea and complex dispersion and assembly of major fragments to present-day configurations during the last 600 m.y.” https://www.sciencedirect.com/science/article/pii/S0012825219302636?via=ihub View in LinkedIn

THE PERSISTENT MYTH. “Precambrian paleomagnetism? Evidence often cited for a permanent liquid core and ancient plate tectonics comes from paleomagnetic interpretations that may be in error.” https://www.sciencedirect.com/science/article/pii/S0012825219302636?via=ihub View in LinkedIn

MAGNETIC SHIELD THESIS. “The Cambrian explosion of evolution produced almost all phyla of modern animals within about 50 m.y., possibly because the newly-formed strong dipolar magnetic field provided a shield against ionized radiation.” https://www.sciencedirect.com/science/article/pii/S0012825219302636?via=ihub View in LinkedIn
