SO ENDS this first of two weekends looking at the issue of the enormous diversity of sex determination mechanisms in organisms. As ever, nature turns out to be very experimental and creative in this issue, and considerable biological capital is invested in this function. The coming weekend will offer a variety of hypotheses for why having different sexes is biologically important. View in LinkedIn

MALE STERILES. “Female flowers are generally smaller, and this reduction in size has been related to the lack of anthers and, more precisely, to the male hormones present in them. Male-steriles do not produce pollen and, due to reallocation of resources, they are expected to produce more seeds, which could explain their maintenance in a population.” https://lnkd.in/d4QE8Rq View in LinkedIn

GYNODIOECIOUS. “Females are actually hermaphrodites which have lost their male function, and they are referred to as male-steriles. This character is genetically determined, and females are similar to hermaphrodites in morphology with the exception of their flowers.” https://lnkd.in/d4QE8Rq View in LinkedIn

VARIOUS MECHANISMS. “In many animals, sex determination involves the entire genome. With haplodiploidy (found in about 12% of animal species, including all ants, wasps, and bees) and paternal genome elimination (found in scale insects), males only transmit their maternal set of genes.” http://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.1001899 View in LinkedIn

RAY KURTZWEIL'S VISION. "Uploading human minds to computers controlling robotic bodies with superhuman capabilities. Consisting entirely of replaceable parts, and provided with safe, out-of-body storage of their memories and psychological states, these beings will be effectively immortal." https://lnkd.in/eiVDpvQ View in LinkedIn

IT IS ONLY INFORMATION. “Information defines your personality, your memories, your skills. And it really is information. And we ultimately will be able to capture that and actually recreate it. So then we will back ourselves up. People a hundred years from now will think it pretty amazing. People actually went through the day without backing up their mind file?” https://lnkd.in/dkSJnr2 View in LinkedIn

KURTZWEIL'S CORRECT PREDICTIONS. "According to Ray Kurzweil, 89 out of 108 predictions he made were entirely correct by the end of 2009. An additional 13 were what he calls “essentially correct" (meaning that they were likely to be realized within a few years of 2009), for a total of 102 out of 108. Another 3 are partially correct, 2 look like they are about 10 years off, and 1, which was tongue in cheek anyway, was just wrong." https://en.m.wikipedia.org/wiki/Predictions_made_by_Ray_Kurzweil View in LinkedIn
