Molecular evolution is the process of evolution at the scale of DNA, RNA, and proteins. It emerged as a field of study in the 1960s as scientists sought to understand recent discoveries on the structure and function of nucleic acids and protein.- Category ID : 417376
Explores the structural relationship between cosmological symmetry-breaking and the form of molecular evolution leading to biological systems on Earth. It thus forms an alternative to historical hypotheses in which the form of biogenesis is believed to be the product of a linked sequence of specific conditions, bridged by stochastic selection processes.
Details work exploring the evolution of novel ribozymes (deoxyribo and ribonucleic acid catalysts) from populations of random sequences, attempting to shed light on the origins of biological catalysis.
Information from Wikipedia on the emergence of this field of study following the rise of molecular biology and the advent of protein sequencing. The differences between homologous sequences can be used as a molecular clock to estimate the time since the last common ancestor.
Paper by Anthonie W J Muller proposing a theory that organisms can use or may have used thermal cycling as an energy source, for example in volcanic hot springs, as an evolutionary step towards photosynthesis.
The study of structural and functional organization of chromosomes, caryotypes, molecular systematics and phylogeny, environmental control of structural and functional features of cell cycle and meta-phase chromosomes in plants.
