MAJOR UPHEAVALS. "Comparisons of the sex chromosomes of the three major mammal groups show that there were two upheavals of sex chromosomes during mammal evolution." https://lnkd.in/ehjz378 View in LinkedIn

A TYPE OF FREEDOM. "The evolution of separate sexes from an initially co-sexual state might be expected to provoke evolutionary changes, as each sex adapts to the release of constraints imposed by the other sex function." https://lnkd.in/exrSaeb View in LinkedIn

SUPPRESSION. "Recombination suppression may involve inversions, for instance in mammals. Other kinds of chromosomal rearrangements, including translocations, can also suppress recombination. Translocations involving sex chromosomes are known in several species, and could be advantageous because they cause linkage between autosomal and sex-linked genes." https://lnkd.in/exrSaeb View in LinkedIn

RECOMBINATION SUPPRESSED. “Given that the sex-determining loci of many animals, as well as a wide diversity of plants, are in non-recombining genome regions, it seems more likely that these genome regions initially recombined, and that selection has acted to suppress recombination." https://lnkd.in/exrSaeb View in LinkedIn

DISRUPTIVE GENES. "A gene can take control of sex development, and can sometimes replace an established system." https://lnkd.in/exrSaeb View in LinkedIn

VIRUSES CREATED LIFE. “Every plant, every animal, and even humans were created in large part by viruses.” https://lnkd.in/guhpmyR View in LinkedIn

SPECIATION. "Strengthening the argument that sex chromosome turnover begets speciation is evidence of a new round of sex chromosome change and speciation." https://lnkd.in/ehjz378 View in LinkedIn

VIRAL CONSORTIA. “Villarreal thinks we need a new language to deal with the dynamic of viruses, which exist as nonlinear collective entities, i.e., consortia. He considers viruses active organisms that are not only the biggest component of the biomass but comprise 10% of the human genome. Villarreal goes as far as saying that “all living habitats . . . have and must operate in a virosphere” — Ex virus omnia (from virus everything) is his motto.” https://lnkd.in/ej7yCCq View in LinkedIn

DEFINING EVENT. "Sex chromosome change has occurred very rarely in mammals, so it seems significant that each change corresponds to a major divergence. That's why I propose that sex chromosome turnover separated monotremes from the rest of the mammals, and sex chromosome fusion occurred later to separate our lineage from marsupials." https://lnkd.in/ehjz378 View in LinkedIn
