PROMISCUOUS HYBRIDS. "When pollinated by facultative apomictic tetraploids, the offspring generated were frequently fertile and highly sexual tetraploid hybrids. This was observed in a fixed setting, but is evidently occurring in nature due to the extensive variability within tetraploid populations that are associated with diploid colonies." http://libres.uncg.edu/ir/asu/f/Mueller,%20Marissa%20Thesis.pdf View in LinkedIn

FRESH TERRITORIES. "Polyploids with two or more genomes seem especially adept at colonizing habitats which are beyond the tolerances of their progenitors. An establishment advantage might also accrue for allopolyploids when neoautoploids have lower fertilities than neoalloploids." https://lnkd.in/eee56_B View in LinkedIn

CHAOTIC FUSIONS. "Diploids often produce cytologically unreduced female gametes, these unreduced gametes can fuse with normal haploid gametes (pollen) to generate triploid hybrids and, even more rarely, fuse with other unreduced gametes to produce tetraploids (having four copies of a single genome)." http://libres.uncg.edu/ir/asu/f/Mueller,%20Marissa%20Thesis.pdf View in LinkedIn

STEPHEN HAWKING. “The human race is just a chemical scum on a moderate-sized planet, orbiting around a very average star in the outer suburb of one among a hundred billion galaxies. We are so insignificant that I can't believe the whole universe exists for our benefit. That would be like saying that you would disappear if I closed my eyes.” https://lnkd.in/e_qnKhM View in LinkedIn

HUMANS AT THE CROWN OF CREATION. “Zaphod “had seen the whole universe stretching to infinity around him—everything. And with it had come the clear and extraordinary knowledge that he was the most important thing in it.” https://lnkd.in/eHpXX48 View in LinkedIn

PERSPECTIVE LOST. “I really believe that if the political leaders of the world could see their planet from a distance of 100,000 miles their outlook could be fundamentally changed. That all-important border would be invisible, that noisy argument silenced.” (Michael Collins, astronaut). https://lnkd.in/eU4ZQBy View in LinkedIn

FRAGMENT FROM NATURE considers the subject of topographic scale in nature. Judging from the complete paucity of literature on the subject, biologists appear rather oblivious of the issue of scale, and this partly explains why the vast majority of biological investigations are earth-centric and pre-Copernican. Thinking biologically beyond our atmosphere is rare. We seem to be the gumboots and magnifying glass type of scientists rather than big thinkers. View in LinkedIn

MEIOSIS MAKES GERM CELLS. "Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females." https://lnkd.in/eF42xiU View in LinkedIn

"MEIOSIS is an ancestral, highly conserved process in eukaryotic life cycles, and for all eukaryotes the shared component of sexual reproduction." https://lnkd.in/etsJH7u View in LinkedIn

IS IT TRUE that evolution has trended in more complex organisms toward sexual reproduction? For the reason of creating greater genetic variety? We take a journey into meiosis and sex in the evolution of creatures on this planet. Why did nature bother to invent sex? View in LinkedIn
