Leaf arrangement steers fern vascular patterns, reshaping evolution of plant stems
New findings overturn a long-standing view of fern vascular evolution In a breakthrough study published in Current Biology, Assistant Professor Jacob S. Suissa of the University of Tennessee, Knoxville, reveals that the way leaves are arranged along a fern stem can steer the evolution of its internal vascular pattern. This challenges a century-and-a-half of research…

Tiny Atlas Blue Butterfly Breaks World Record with 229 Chromosome Pairs
Introduction The Atlas blue butterfly, Polyommatus atlantica, has broken a long-standing evolutionary record by possessing 229 pairs of chromosomes—the highest number reported in any multicellular animal. Genomic confirmation comes from teams at the Wellcome Sanger Institute and the Institute of Evolutionary Biology. The researchers describe a genome where chromosomes have been broken up over time…
