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

A SMIDGE OF NOTHING. “Roughly 70% of the universe is made of dark energy. Dark matter makes up about 25%. The rest — everything on Earth, everything ever observed with all of our instruments, all normal matter adds up to less than 5% of the universe.” https://nasa.tumblr.com/post/136762377389/7-facts-that-will-make-you-feel-very-small View in LinkedIn

TRIGGER UNRESOLVED. "In conclusion, although abiotic and oxidative stresses seems to play a role in the transition from somatic to reproductive fate and the regulation of (apo)meiosis, their potential role as a driving force promoting sexual or asexual reproduction remains unclear and warrants further investigation." https://lnkd.in/ewV3vWP View in LinkedIn

2-FOLD FITNESS ADVANTAGE. "The theoretical difficulties associated with explanations for the evolution of sex are well-known; there is up to a two-fold advantage to asexual reproduction over sexual reproduction. Thus, if asexual reproduction results in the production of equal numbers and viability of offspring (the ‘all-else-being-equal’ assumption), then asexual females will produce twice as many reproducing offspring as sexual females." https://lnkd.in/gGTTSzx View in LinkedIn

PERSISTENT STRATEGY. "Sex, once evolved, is a remarkably persistent evolutionary strategy – most eukaryotes reproduce sexually." https://lnkd.in/gGTTSzx View in LinkedIn

ONE WAY STREET. "An alternative explanation for the predominance of sex is that it is difficult for an organism to accomplish asexual reproduction once sexual reproduction has evolved. Difficulty in returning to asexuality could reflect developmental or genetic constraints." Although some organisms do vary between states. https://lnkd.in/gGTTSzx View in LinkedIn

OCCULT REASON. "Asexual reproduction could offer up to a two-fold fitness advantage over sexual reproduction, yet higher organisms usually reproduce sexually." https://lnkd.in/gGTTSzx View in LinkedIn

CRITICAL INNOVATION. "Meiosis is a key event of sexual life cycles in eukaryotes. Its mechanistic details have been uncovered in several model organisms and most of its essential features have received various and often contradictory evolutionarily interpretations." https://lnkd.in/e2tp_G5 View in LinkedIn
