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

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

APOMIXIS TRAIT. "When crop species acquire this trait, superior genotypes, including hybrids, will be fixed and seeds will be multiplied without segregation of superior gene combinations." http://journals.tubitak.gov.tr/agriculture/abstract.htm?id=16663 View in LinkedIn

BLACK BOX. "The molecular mechanisms controlling apomixis, a mode of asexual reproduction in plants leading to clonal seed formation, are largely unknown." https://lnkd.in/dKiMTaq View in LinkedIn

PARTHENOGENESIS GENE. "This study presents the first demonstration, to our knowledge, of function for a gene cloned from a naturally occurring apomictic plant that encodes a key component controlling parthenogenesis." http://www.pnas.org/content/112/36/11205.full View in LinkedIn

BINARY FISSION. "Fission, also called binary fission, occurs in prokaryotic microorganisms and in some invertebrate, multi-celled organisms. After a period of growth, an organism splits into two separate organisms. Some unicellular eukaryotic organisms undergo binary fission by mitosis." https://lnkd.in/d_e3R-w View in LinkedIn

FISSION. "In other organisms, part of the individual separates, forming a second individual. This process occurs, for example, in many asteroid echinoderms through splitting of the central disk. Some sea anemones and some coral polyps also reproduce through fission." https://lnkd.in/d_e3R-w View in LinkedIn

ANCIENT METHOD. "Organisms in the domains of Archaea and Bacteria reproduce with binary fission." https://lnkd.in/dwsn3wd) View in LinkedIn
