It has recently been proposed that the caudal curvature (concave caudal side) observed in the radioulna of terrestrial quadrupeds is an adaptation to the habitual action of the triceps muscle which causes cranial bending strains (compression on cranial side). The...

Without exception, modern hypotheses explaining the origin of eukaryotes assume evolution from two (or more) distinct prokaryotes. Almost all prokaryotic cell membranes possess a chemiosmosis system, whereas eukaryotic cell membranes have lost that ability. Nevertheless,...
