NEGLIGIBLE RISK OF DEATH. ""The combination of modular growth and dormancy in perennial plants, two features individually shared with some animals, increases their plasticity and strongly reduces the potential damage caused by aerobic life, to the extreme that the likelihood of dying from aging is, at best, negligible." https://lnkd.in/d5nsZwQ View in LinkedIn

CORRECTIVE VIEWPOINT. "There is a common belief that Redwood trees and Bristle cone pines can achieve great age. Yet, the cells in these trees, alleged to be thousands of years old, are dead. The living cells in the needles, cambium layer and root hairs are no older than about 30 years. Humans, older than 30 years, who stand in awe of Redwood trees should more accurately stand in awe of their own living post mitotic neurons that are older than the tree’s living cells." https://lnkd.in/esfPTAR View in LinkedIn

HAYFLICK LIMIT CONSENSUS. "Since our first tentative suggestion that the finite lifespan of cultured normal human cells was a manifestation of aging at the cellular level, an enormous fund of knowledge has been acquired about the nature of the phenomenon. Few if any of the experimental results that have been reported are completely incompatible with an interpretation that the finite lifetime of cultured normal cells is aging at the cell level." http://protein.bio.msu.ru/biokhimiya/contents/v62/full/62111380.html View in LinkedIn

SO ENDS the first of two weekends dedicated to the curious orchid family. The nuanced strategies employed by these flowers for reproduction by false representation require a close co-evolution. These plants have no centralized brains, no vertebrate eyes, yet they can mirror the needs of a variety of pollinators with ingenious accuracy, and, according to the theory of evolution, all by dumb trial and error. No wonder Darwin was mesmerized by these clever plants. View in LinkedIn

PLANT MODULARITY AND SENESCENCE. "However, maintaining organism integrity with increased complexity in an evolutionary timescale has some costs. In a meta-analysis of plant life-history tables, data provided by Silvertown et al. support the idea that organisms which remain integrated in modules are more likely to senesce than organisms whose ramets separate into unconnected entities." http://onlinelibrary.wiley.com/doi/10.1111/j.1469-8137.2010.03360.x/full View in LinkedIn

PLANT MODULARITY "seems to increase organism plasticity in terms of whole-organism regeneration, a property that has been maintained with increasing complexity during evolution of species over time within the plant kingdom, but not within the animal kingdom." http://onlinelibrary.wiley.com/doi/10.1111/j.1469-8137.2010.03360.x/full View in LinkedIn

REGENERATION. "By contrast, some animals, such as zebrafish, can restore normal organ (heart) function after severe injury, and a few species of animals, such as some marine clonal invertebrates (e.g. many cnidarians), can even regenerate their entire body as a result of their modular development, a trait shared with plants.” http://onlinelibrary.wiley.com/doi/10.1111/j.1469-8137.2010.03360.x/full View in LinkedIn

REGENERATIVE CELLS IN ANIMALS. "A single haematopoietic stem cell can reconstitute the entire haematopoietic system of an irradiated mammal. Progenitor cell populations have been identified within most mammalian organs, including skin, blood, bone, reproductive tissues, skeletal muscle, kidney, lung, liver, intestine, heart and brain." http://onlinelibrary.wiley.com/doi/10.1111/j.1469-8137.2010.03360.x/full View in LinkedIn

REGENERATIVE CELLS IN PLANTS. "Other species, such as some herbaceous perennials, can also survive for centuries by keeping their meristems intact." http://onlinelibrary.wiley.com/doi/10.1111/j.1469-8137.2010.03360.x/full View in LinkedIn

"THE IMMORTAL MEDUSA is the most miraculous species in the entire animal kingdom...I believe it will be easy to solve the mystery of immortality and apply ultimate life to human beings.” http://wedcrew.yolasite.com/resources/Jelly%20fish.pdf View in LinkedIn
