STRANGE PHENOMENA. "There is wide interest in understanding sex chromosome evolution, which involves strange phenomena such as selection for suppression of genetic recombination (which is widespread throughout the genomes of most organisms, other than in parts of the sex chromosomes), and the resulting ‘genetic degeneration’ involving loss of function, or complete loss, of many genes on the non-recombining chromosome; this chromosome is the Y in XY systems, and the W in ZW systems such as that of birds and Lepidoptera, and a few plants." https://lnkd.in/exrSaeb View in LinkedIn

BACTERIOPHAGES AND VIRUSES. “And as the most numerous biological entities on the planet, with great—if far from fully understood—relevance for global nutrient cycling and gene dispersal, phages and other viruses represent an important and largely unexplored frontier in ecology.” https://lnkd.in/gPxMKj9 View in LinkedIn

REPEATED EVENTS IN PLANTS. "It is now well established that plants have an important place in studies of sex chromosome evolution because of the repeated independent evolution of separate sexes and sex chromosomes." https://lnkd.in/exrSaeb View in LinkedIn

VERY NEW FINDING. “Bacteriophages, or viruses that infect bacteria, have been known to science for less than a hundred years and remain at the periphery of our perception of life.” https://lnkd.in/gPxMKj9 View in LinkedIn

CRITICAL TRANSITION. "The evolution from hermaphroditism to dioecy (separate sexes) is considered one of the most important evolutionary transitions in the reproductive history of angiosperms. Although relatively rare (approx. 6 % of species), dioecy is a widespread reproductive system in angiosperms (reported in approx. 38 % of families." https://lnkd.in/guzeMTD View in LinkedIn

INTERMEDIATE STEP. "Although a direct transition has sometimes been suggested, the transition probably involved intermediate steps in most cases, as it seems unlikely that male and female sterility mutations arise simultaneously in hermaphroditic species." https://lnkd.in/guzeMTD View in LinkedIn

"SEXUAL DIMORPHISM describes differences between the sexes in primary and secondary sex characters. The former relate directly to male (androecium) and female (gynoecium) sexual organs, and the latter to differences between the sexes in structures other than sex organs themselves, including any aspect of morphology or physiology." https://lnkd.in/ge7JD6J View in LinkedIn

SO ENDS the reminder that the message of the Flammarion engraving of 1888 is as true today as it was back then, and however much we may pat ourselves on the back about the progress of science, we are still primitive hominids living in the dark ages. The roar of applause for Nobel Laureates may be humbled by the pall of darkness we live in. Less than one percent of life is known. It is our epitaph. View in LinkedIn
