THOUGHTS, experiences, emotions and memories are chemically and electrically coded information in our minds. When we save a regular file on the computer to the hard drive, it is electronically coded information. What is the basis for thinking we could take that warm wet thing called a brain and put it into I/O electronic code? And, like the concept of intelligent machines, that it could continue to think, experience, feel and remember? View in LinkedIn

UNLIKELY PROBABILITY. “Exhibit A: The laws of probability theory dictate that as a story gets more complicated, and depends on the truth of more and more claims, its probability of being true decreases.” https://lnkd.in/daiyRaS View in LinkedIn

BRAIN UPLOADING? When I first read Ray Kurtzweil's ideas about putting consciousness on a computer or the web, I simply thought that he had lost it, despite his evident credentials. Such an outrageously novel idea seemed similar to claims that death was old hat (wait for this theme!). I was troubled by the biochemical and anatomical conundrum of putting your brain on a pen-drive. We have nothing to lose but to gander down this lane and take a look. View in LinkedIn

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

SOME PLANTS HAVE “the coexistence of females and hermaphrodites. Although females exist extensively among hermaphroditic plant species, they are present at a noticeable frequency in only a few species, which are termed gynodioecious.” https://lnkd.in/d4QE8Rq View in LinkedIn
