SHUNT TRANSITIONS. "Babies born prematurely often have difficulty with the transition to normal postnatal circulation because they retain fetal circulatory patterns due to delayed shunt closure." https://evolution-outreach.springeropen.com/articles/10.1186/s12052-014-0012-5 View in LinkedIn

SURVIVAL OF MUTANT PLANTS. "At the end of the Edo era in particular, a great number of varieties were produced. However, some of them were overshadowed by simple large-blossomed morning glories and became extinct before becoming popular among people. However, others have been conserved by the efforts of some hobbyists, although they were not cultivated widely, and have survived even to this day." https://lnkd.in/dqHKMaU View in LinkedIn

BYPASS VESTIGE. "Foramen ovale → fossa ovalis. This bypass, essentially an oval-shaped hole in the septum dividing the right and left atria, normally closes when the pressure head in the systemic (left) half of the mammalian circulation exceeds that of the pulmonary division, pressing a flap of tissue to close the hole. The tissues soon fuse and all that remains is an oval-shaped depression. However, up to 30% of adult humans retain a patent foramen ovale (PFO, or atrial septal defect." https://evolution-outreach.springeropen.com/articles/10.1186/s12052-014-0012-5 View in LinkedIn

FRAGMENT FROM NATURE continues from the musings on the Japanese idea of the suchness of things in nature, the beauty of transience and imperfection. It appears that as part of this view of the world, the advanced horticulture of plants was in part a meditation on the theme, exemplified by the many remarkable (and many lost) varieties of morning glory flowers that they bred, and the (coincident?) rise of the wild tulip forms in Holland, formed by transposons and viruses, respectively.

VESTIGIAL SHUNTS. "Such circulatory shunts, listing the original fetal and ensuing neonatal ‘vestigial’ vessels or structures." https://evolution-outreach.springeropen.com/articles/10.1186/s12052-014-0012-5 View in LinkedIn

FEMALE SEX CHORD VESTIGES. "In females, the primary medullary sex cords degenerate, where they may remain as ontogenetic vestiges, and instead secondary sex cords invade the cortex of the gonad and become ovarian follicles." https://evolution-outreach.springeropen.com/articles/10.1186/s12052-014-0012-5 View in LinkedIn

EMBRYONIC CIRCULATION. "Embryonic remnants of mammalian circulation. some of the best examples of non-functional developmental ‘vestiges’ involve mammalian circulatory changes. These are detours or shunts (pulmonary to systemic, or ‘right to left’) occurring in the shift from fetal to neonatal mammalian circulation." https://evolution-outreach.springeropen.com/articles/10.1186/s12052-014-0012-5 View in LinkedIn

MALE SEX CHORD VESTIGES. "Primary and secondary sex cords in indifferent gonads. Primary sex cords of the gonad’s medullary region become Sertoli cells of the seminiferous tubules that comprise the majority of the testes; later rete cords (AKA cords of urogenital union) connect these to the efferent duct (essentially, the vas deferens)." https://evolution-outreach.springeropen.com/articles/10.1186/s12052-014-0012-5 View in LinkedIn

MULLERIAN DUCT VESTIGES. "In females, the Mullerian duct becomes the oviduct, including the Fallopian tubes, uterus, cervix, and upper portion of the vagina, whereas in males the Mullerian duct regresses completely or is seen as a small remnant." https://evolution-outreach.springeropen.com/articles/10.1186/s12052-014-0012-5 View in LinkedIn

SEXUAL DUCT VESTIGES. "In males, the Wolffian duct becomes the efferent or deferent duct (including the epididymis, vas deferens, and seminal vesicle) that stores and transports sperm and seminal fluids. In females, the Wolffian duct degenerates and remains solely as a withered rudiment." https://evolution-outreach.springeropen.com/articles/10.1186/s12052-014-0012-5 View in LinkedIn
