| kanzure | "In Biological Emergences, Robert Reid argues that natural selection is not the cause of evolution. He writes that the causes of variations, which he refers to as natural experiments, are independent of natural selection. Reid proposes an alternative theory to explain how emergent novelties are generated and under what conditions they can overcome the resistance of natural selection. He suggests that what causes innovative variation ... | 05:24 |
| kanzure | ... causes evolution, and that these phenomena are environmental as well as organismal. After an extended critique of selectionism, Reid constructs an emergence theory of evolution, first examining the evidence in three causal arenas of emergent evolution: symbiosis/association, evolutionary physiology/behavior, and developmental evolution. Without selectionism, Reid argues, evolutionary innovation can more easily be integrated into a ... | 05:24 |
| kanzure | ... general thesis. Finally, Reid proposes a biological synthesis of rapid emergent evolutionary phases and the prolonged, dynamically stable, non-evolutionary phases imposed by natural selection." | 05:24 |
| kanzure | oh weird, wikipedia cites natural selection as a "cause" of genetic change? i guess so: "Natural selection is the only known cause of adaptation but not the only known cause of evolution. Other, nonadaptive causes of microevolution include mutation and genetic drift.[19]" | 05:29 |

| kanzure | not sure that is true, the behavioral differences were already presenting themselves as a result of genetics, and then they were prioritized and elaborated | 07:02 |

| kanzure | "Second, there may simply be few domestication loci with major effects in animals. Early animal domestication may have happened by shifting the allele frequencies at many loci, each with small individual effects, thereby altering the phenotype.

| kanzure | gerontology research group mailing list has exploded with questions about "what is a reddit" and "how do i use reddit" | 12:32 |
| kanzure | i guess this is predictable since none of them seem to understand technology | 12:32 |
| kanzure | that's the poeple we have looking into anti-aging, peeps :-/ | 12:33 |
| drethelin | wait so | 12:33 |
| drethelin | did she become CEO of this company to reverse her own aging? | 12:33 |
| kanzure | finding a patient that is well-informed is difficult, and perhaps she found a legal loophole for using herself as ceo as patient zero | 12:33 |
| kanzure | usually "patient zeros" for this type of work requires someone who can sign off on informed consent and has medical background and law background, so that you can be protected from them coming back in the future and suing about something gone terribly wrong. i forget where i first saw this strategy though.... | 12:34 |
| drethelin | well legally speaking as long as the procedures and chemicals aren't illegal to acquire it's perfectly legal to just chomp them yourself right | 12:34 |
| drethelin | I don't think it's illegal to test things on yourself | 12:34 |
| kanzure | let me introduce you to the fda :-) | 12:34 |
| kanzure | i mean, i agree with you that what you put into your body is your own business, but.... | 12:35 |
| kanzure | http://diyhpl.us/wiki/fda/ | 12:35 |
| drethelin | all of those are because of distribtion and sales to others though | 12:36 |
| drethelin | don't get me wrong the FDA is awful | 12:36 |
| kanzure | hmm maybe i am thinking of patent law, can't find any evidence about this with the fda | 12:38 |

| kanzure | bioviva probably didn't pioneer this trick but essentially instead of buying a drug, the ceo bought shares in a company that is going to give her the drug, which is essentially selling the drug to the ceo, heh | 12:38 |

| kanzure | but more realistically: | 12:41 |
| kanzure | ask about existing open-source brain emulation software frameworks, or plans for such, or good architecture strategies for such | 12:41 |
| archels | kanzure: this Barkley guy is pretty full of himself | 12:42 |
| kanzure | also ask them whether they use modeldb or the eventual fate of modeldb, how many physiologically characterized neurons they expect to see on the interwebs, and who maintains or tests those models long-term | 12:42 |
| kanzure | archels: yes that's true, he is the prototypical "psychiatrist" person. i'm pretty sure he is a clone of the dude from what about bob. | 12:43 |

| streety | you don't need to cryo-preserve for that though. Fixed specimens would likely work just as well | 12:45 |
| drethelin | Kanzure: I think the closest we've come to that is we can completely replace the genome of some simple cells | 12:46 |
| maaku | streety: maybe. but it's lot a lot of effort to cryopreserve an adam and an eve for each, plus 100+ cell samples from other specimens | 12:46 |
| kanzure | although, it would be interesting to try to take a breeding approach to the mycoplasma laboratorium problem... instead of just stripping everything out of the genome, you (over a number of rounds of iteration and selection) progressively strip things out of the chasis, such that the genome has to self-bootstrap a greater number of its own components, until you can bootstrap cells from in vitro protein reactions in a single pot. | 12:47 |
| maaku | or even just the female would probably do | 12:47 |
| maaku | *it's not a lot of effort | 12:47 |
| kanzure | (what would a genome look like if it had to constantly refer to how to bootstrap the cell membrane from nothing? polymerase might attach somewhere random at first. i guess you could say a few primers are okay to include....) | 12:47 |
| kanzure | streety: fixed specimens? | 12:47 |
| kanzure | drethelin: yes we can replace the genome, that's true | 12:48 |
| maaku | kanzure: I assume he means plastination | 12:48 |
| maaku | which would also be better than nothing... | 12:48 |
| kanzure | huh? | 12:48 |
| kanzure | .wik plastination | 12:48 |
| yoleaux | "Plastination is a technique or process used in anatomy to preserve bodies or body parts, first developed by Gunther von Hagens in 1977. The water and fat are replaced by certain plastics, yielding specimens that can be touched, do not smell or decay, and even retain most properties of the original sample." — https://en.wikipedia.org/wiki/Plastination | 12:48 |
| kanzure | huh? how would that help | 12:49 |
| maaku | anatomical comparison? idk. I'm not arguing for it | 12:49 |
| kanzure | heh lousy steelman :-) but ok | 12:50 |
| maaku | much better to cryopreserve a viable female | 12:50 |
| kanzure | eggs and sperm are much easier to preserve; once you get an egg and embryo that can develop in $arbitrary_mammalian_womb then you have much better chances of resuscitation later. but which is harder: getting an embryo that can develop more easily in alternative wombs, or getting cryonics to work? :-) | 12:51 |

| maaku | kanzure: I'm equally interested in the memories stored in an adult specimen, at least for social species | 12:57 |
| kanzure | ah right you mentioned this the other day | 12:58 |
| maaku | preserving genetics doesn't preserve culture | 12:58 |
| kanzure | you want cinamax/technocolor playback of ancient t-rex memory? | 12:58 |
| maaku | that would be nice | 12:58 |

| maaku | of course memories don't work that way, but you know that | 12:59 |
| drethelin | this makes me want to play an assassin's creed game that lets you play as a bunch of animals | 12:59 |
| kanzure | epigenetic basis of memory is still being figured out, but dna from >1 million years ago is already nucleated to hell and back :-( | 13:00 |
| maaku | hahaha that would be awesome | 13:00 |
| kanzure | maybe siberia though | 13:00 |
| maaku | I'll be clear that I hold no hope for >1mya samples being recoverable ... but today's technology is primitive | 13:01 |
| kanzure | well if you had your nanofog of molecular nanotechnology, you could go digging in siberia to find deep frozen dna molecules | 13:01 |
| maaku | if I could destructively disassemble a soft-tissue fossil and get the exact structure and location of every molecule, computer science can do more than chemistry in geneme recovery | 13:02 |
| maaku | see for example the shredded stasi files | 13:02 |
| maaku | sadly Ötzi was already defrosted numerous times before he was found, but imagine if another ice man discovery were made, and he was kept frozen until such technology existed | 13:04 |
| maaku | if any of his linguistic memories were recoverable, that alone would solve a lot of questions about pre-history | 13:05 |

All of these changes have been documented in direct observations of the rat in the 19th century, by archaeological evidence, and confirmed by animal breeders in the 20th century.[22] A 2014 commentary published in Genetics proposed that many of these features may arise due to mild neural crest deficits that also ... | 14:51 |

| kanzure | "Inter-individual differences in many behaviors are partly due to genetic differences, but the identification of the genes and variants that influence behavior remains challenging. Here, we studied an F2 intercross of two outbred lines of rats selected for tame and aggressive behavior towards humans for more than 64 generations. By using a mapping approach that is able to identify genetic loci segregating within the lines, we identified ... | 14:55 |
| kanzure | ... four times more loci influencing tameness and aggression than by an approach that assumes fixation of causative alleles, suggesting that many causative loci were not driven to fixation by the selection. We used RNA sequencing in 150 F2 animals to identify hundreds of loci that influence brain gene expression. Several of these loci colocalize with tameness loci and may reflect the same genetic variants. Through analyses of ... | 14:55 |
| kanzure | ... correlations between allele effects on behavior and gene expression, differential expression between the tame and aggressive rat selection lines, and correlations between gene expression and tameness in F2 animals, we identify the genes Gltscr2, Lgi4, Zfp40 and Slc17a7 as candidate contributors to the strikingly different behavior of the tame and aggressive animals." | 14:55 |
