HYPOTHESIS 6. “Two sexes might have served to enable the development of sex specific and sex antagonistic traits.” http://www.sciencedirect.com/science/article/pii/S1749461315000391 View in LinkedIn
HYPOTHESIS 5. “Having two defined mating types or sexes may have enabled specialization of gametes and differential contribution of resources, giving rise to certain development outcomes that we observe such as the transition from isogametic species to anisogametic ones.” http://www.sciencedirect.com/science/article/pii/S1749461315000391 View in LinkedIn
HYPOTHESIS 4. “Having two mating types or sexes may have evolved as a response to conflicts between nuclear and mitochondrial genomes, or between mitochondrial genomes, and thereby given rise to uniparental inheritance of mitochondria and chloroplasts.” http://www.sciencedirect.com/science/article/pii/S1749461315000391 View in LinkedIn
HYPOTHESIS 3. “Having two sexes may be also to restrict inbreeding compared to one universal mater that can mate with itself as well as with anyone else.” http://www.sciencedirect.com/science/article/pii/S1749461315000391 View in LinkedIn
HYPOTHESIS 2. “It may serve to restrict outbreeding compared to populations or species in which there is one universal mating type that can mate with anyone.” http://www.sciencedirect.com/science/article/pii/S1749461315000391 View in LinkedIn
HYPOTHESIS 1. “It may be to increase the efficiency of mate recognition and fusion.” http://www.sciencedirect.com/science/article/pii/S1749461315000391 View in LinkedIn
THE QUESTION. “Why are there most commonly two sexes? We do not know the answer to this seemingly simple question, but hypotheses abound.” https://lnkd.in/dznCAiQ View in LinkedIn
FRAGMENT FROM NATURE continues from last weekend and concludes this weekend on the issue of why there are at least two sexes in many species. This question has generated many hypotheses, some of which will be outlined because they are interesting in and of themselves, regardless of their veracity. View in LinkedIn
PASSING THE TURING TEST. “Do you think we will ever build conscious machines? I’m not sure why we would. But there is no question in my mind that we will build smart machines that can pass the Turing test well before we understand the true biological basis of human intelligence. And I think there are dangers associated with that which most people, being blithe optimists, completely ignore.” http://www.pri.org/stories/2014-06-09/scientists-are-starting-worry-about-conscious-machines-movie-transcendence View in LinkedIn
