"SUPPLE ADAPTATION is not to be equated with natural selection. For one thing, natural selection is not necessary for supple adaptation." https://lnkd.in/da-Njua View in LinkedIn
BEDAU CONCEPT. "Supple adaptation refers to the fact that living systems have an unending capacity to find new unpredictable adaptive solutions to unanticipated changes in the environment." https://lnkd.in/dEj5vVD View in LinkedIn
MARK BEDAU DEFINITION. "I propose that an automatic and continually creative evolutionary process of adapting to changing environments is the primary form of life...what is distinctive of life is the way in which evolution automatically fashions and refashions appropriate strategies for coping as local contexts change." https://lnkd.in/da-Njua View in LinkedIn
SIMPLEST DEFINITION. "E. Mayr: “We shall regard as alive any population of entities which has the properties of multiplication, heredity and variation.” https://lnkd.in/dEj5vVD View in LinkedIn
OMNE VIVUM. "Pasteur demonstrated that life does not arise in areas that have not been contaminated by existing life. Pasteur's empirical results were summarized in the phrase Omne vivum ex vivo, Latin for "all life [is] from life".” https://lnkd.in/eJXtXQy View in LinkedIn
SO ENDS this first weekend on plant dormancy. This phenomenon is not limited to plants. It is a mechanism to allow the organism to wait for favorable conditions for growth and reproduction, by being largely quiescent. We still know relatively little about the phenomena. Next weekend we will look at the genetic findings behind dormancy. View in LinkedIn
EPIGENETIC VERNALIZATION. "Cell division appears to only be required to stabilize the epigenetic-mediated vernalization response in Arabidopsis. Moreover, a stable versus transient vernalization response differentiates monocarpic Arabidopsis from its relative, polycarpic Arabis alpina." https://lnkd.in/duazcMZ View in LinkedIn
DISCREPANCY. "The quiescence of cells during chilling-induced dormancy release has been suggested as a possible discrepancy between vernalization and dormancy release." https://lnkd.in/duazcMZ View in LinkedIn
DORMANCY RELEASE. "We focus on the release of bud dormancy and the floral transition, post-embryonic responses of shoot meristems that occur in trees. A dormant meristem is unable to resume growth under favorable conditions; however, the dormant state is quantitative with endogenous and environmental signals continually altering the depth of dormancy (propensity for growth given advantageous conditions." https://lnkd.in/duazcMZ View in LinkedIn
BIOLOGISTS debate whether viruses are alive, and have done so for a long period of time. With equal lack of resolution, they engage in endless debates about the definitions of life. Both topics are capable of making rational people apoplectic. View in LinkedIn
