THE EUK MYTH. "The list of eukaryotic species that lack strong direct evidence for meiotic sex, but that seem sexual, as suggested by the presence of these meiosis-associated genes, is growing longer and longer." https://lnkd.in/deZ8DED View in LinkedIn
EUK AND EPISODIC SEX. "Hence, from the perspective of cell lineage, sex in multicellular organisms is as episodic as it is in facultatively sexual unicellular eukaryotes. Indeed, tens to hundreds of clonal cell divisions may occur in the germ line of different multicellular organisms." https://lnkd.in/deZ8DED View in LinkedIn
EUK CLONALITY. "In fact, a multicellular organism is “nothing else than” a clonally propagating population of cells that are physically linked." A contrarian viewpoint. https://lnkd.in/deZ8DED View in LinkedIn
EUK SEXUAL REPRODUCTION. "The prevailing view seems to be that multicellular organisms are obligately sexual while clonally reproducing representatives are an oddity, whereas microbial eukaryotes (protists) are perceived as just facultatively sexual, or even purely clonal." https://lnkd.in/deZ8DED View in LinkedIn
GENE DIFFUSION. "An analysis confirms the long-standing theory that sex increases the rate of adaptive evolution by accelerating the speed at which beneficial mutations sweep through sexual, as opposed to asexual, populations." https://lnkd.in/dNRpdc2 View in LinkedIn
NORMAL DISTRIBUTION CURVE. "As predicted by theory, the advantage to sex arises because sexually derived progeny are more variable in fitness, allowing for faster adaptation. This “long-term advantage” builds over multiple generations, eventually resulting in higher fitness of sexual types." https://lnkd.in/ePUmiA8 View in LinkedIn
CORRELATED TO ADAPTION. "Using experimental populations of the facultatively sexual rotifer Brachionus calyciflorus, we show that rates of sex evolve to higher levels during adaptation but then decline as fitness plateaus." https://lnkd.in/ePUmiA8 View in LinkedIn
SEX ENHANCES ADAPTATION. "Both theory and experiments have demonstrated that sex can facilitate adaptation, potentially yielding a group-level advantage to sex." https://lnkd.in/ePUmiA8 View in LinkedIn
