SO ENDS this foray into hybrids and speciation. Tullimonstrum (the Tully Monster) has been a taxonomic conundrum for a long time, seemingly cobbled together from various taxa and without comparator, and is fossil proof of the extreme of speciation weirdness. It will not be the last such example. https://lnkd.in/dm8QrFv View in LinkedIn

OTHER MECHANISMS. "Admixture can simultaneously bring together many new combinations of alleles, generating multilocus novelties that might never have appeared via gradual accumulation of new mutations in a single population. Gene exchange is not the sole, nor even necessarily most likely, source of evolutionary novelty, but is perhaps the most likely mechanism of sudden, population level change. Transgressive segregation might be just the mechanism to make more monsters hopeful." http://link.springer.com/article/10.1007/s11692-012-9209-0 View in LinkedIn

REGULATION OF MULTIPLE FISSION. "We describe the different organizational types of multiple fission cell cycles, with distinct timing of DNA replication, nuclear, and cellular divisions, and discuss how they are regulated at physiological and molecular levels." https://lnkd.in/dDMwBQq View in LinkedIn

ORGANELLE FISSION. "This form of asexual reproduction and cell division is also used by some organelles within eukaryotic organisms (e.g., mitochondria). Binary fission results in the reproduction of a living prokaryotic cell (or organelle) by dividing the cell into two parts, each with the potential to grow to the size of the original." https://lnkd.in/dwsn3wd) View in LinkedIn
