CHRISTMAS RANT. We could argue that bacteria and viruses have appropriated the mighty and foolish human brain. We have been fooled by our hierarchical prejudices. Smart folk have not understood what is in plain sight. These are the most smart creatures on the planet, or even the universe, which may indeed be their real home. View in LinkedIn

CHRISTMAS RANT. Foolish humans! So smug that we cannot read sophistication. Foolish humans! That we still think like people two thousand years ago. Foolish humans! That we cannot see what is in plain sight. View in LinkedIn

PURPOSE OF LIFE. “Biology, as it is presently taught, answers that the purpose is to produce the next generation...There is nothing except continuity, no purpose except continued existence, now or in the future.” (Professor Sir Fred Hoyle, who coined the term the Big Bang). https://lnkd.in/egyjqhU View in LinkedIn

SEXUAL REPRODUCTION requires two parents which share equal amounts of genetic information in the offspring. Meiosis creates the germ cells. It is a strategy used by most of the animal kingdom and by many plants, whose flowers are their sexual organs. View in LinkedIn

DIPLOID TO HAPLOID. "Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. During reproduction, when the sperm and egg unite to form a single cell, the number of chromosomes is restored in the offspring." https://lnkd.in/eTsFK2C View in LinkedIn

THE TOPIC BREADTH. "We discuss the origin of meiosis (origin of ploidy reduction and recombination, two-step meiosis), its secondary modifications (in polyploids or asexuals, inverted meiosis), its importance in punctuating life cycles (meiotic arrests, epigenetic resetting, meiotic asymmetry, meiotic fairness) and features associated with recombination (disjunction constraints, heterochiasmy, crossover interference and hotspots)." http://biorxiv.org/content/biorxiv/early/2016/04/28/050831.full.pdf View in LinkedIn

TWO STEPS. "In eukaryotic sexual life cycles, haploid cells fuse to give rise to diploids, before diploid cells are converted back to haploids in a process known as meiosis." http://biorxiv.org/content/biorxiv/early/2016/04/28/050831.full.pdf View in LinkedIn

HALVING AND REFRESHENING. "Meiosis reduces a cells chromosome number by half, whilst also creating new allele combinations distributed across daughter cells through segregation and recombination." http://biorxiv.org/content/biorxiv/early/2016/04/28/050831.full.pdf View in LinkedIn

KEY TO MEIOSIS SUCCESS. "This genetic reshuffling reduces genetic associations within and between loci and is thought to be the basis of the success of sexual reproduction." https://lnkd.in/e2tp_G5 View in LinkedIn

EVOLUTIONARY SIGNIFICANCE. "Mechanistic studies of meiosis have been carried out in different fields, such as cell biology, genetics and epigenetics, encompassing a wide range of eukaryotes. However, these studies rarely focus on the evolutionary significance of meiotic mechanisms, rather mentioning them in passing and often in a simplified manner." http://biorxiv.org/content/biorxiv/early/2016/04/28/050831.full.pdf View in LinkedIn
