Systems analysis of leaf anatomy and transcriptome using unsupervised machine learning provides insight on photosynthesis development and evolution in non-model grasses. [PDF]

Plant Direct
Abstract The C4 photosynthesis includes intriguing leaf anatomies. The current model supports the placement of C3‐C4 intermediates as a middle point in the evolutionary trajectory from C3 to C4 photosynthesis. The known determinants involved in the differentiation of divergent photosynthetic leaves arose from the comparative analysis between both ends,

Ribcage Morphology in Native South American Populations From Different Altitudes: Insights From a Global Comparative Framework. [PDF]

Am J Hum Biol
ABSTRACT Objectives Altitude shapes human morphology as highland populations must cope with cold and hypoxic environments. Although Andean highlanders have been proposed to exhibit larger and deeper ribcages, this idea is mainly based on research using disarticulated skeletal elements or non‐South American controls. The objective of this research is to
