Complex Life Emerged from Sea Earlier Than Thought Live Science
WebThe first kind is a planar (traveling) wave based on flagella of eukaryotic cells, which is described by a traveling harmonic wave . Linear and quadratic traveling waves define the Carangiform fishes motion, i.e., the bending of their bodies in a propulsive wave that extends from head to tail end [ 50 ]. Modern evidence suggests that early cellular evolution occurred in a biological realm radically distinct from modern biology. It is thought that in this ancient realm, the current genetic role of DNA was largely filled by RNA, and catalysis was also largely mediated by RNA (that is, by ribozyme counterparts of enzymes). This concept is known as the RNA world hypothesis. According to this hypothesis, the ancient RNA world transitioned into the modern cellular world … bookings bcmm.ca
