Apr 26	comment	Digestion system startup? I think the studies cited here only care about how many calories and the glycemic index of what you eat. Its not usually done to break down diet studies into particular items. So better to have a piece of toast and a cup of tea rather than say three pieces of cake.

Apr 26	comment	Can animals, like monkeys, be homosexual? bisexuality for instance is very much a feature for bonobos - it creates their social structure...
Apr 26	comment	Can animals, like monkeys, be homosexual? @rg255 I wasn't disputing you could find such examples. I suppose there may be animals that can't tell the difference between genders or individuals, but on the average I would doubt it. Even microoganisms can be specific; this would be an evolutionary 'feature' not a 'bug'. So its possible if there were something it does for the organism because there is a cost - disease spreads easily and there is some opportunity cost to mating. Competition would be on sperm competition rather than mate choice. They ought to be induced to mate with inanimate objects with specific visual cues.
Apr 25	comment	Can animals, like monkeys, be homosexual? Just as a comment, I'd be surprised if animals got confused and couldn't tell the gender of the individuals they are trying to mate with. If a vet can tell the difference, which is the case in most animals, the animals themselves shouldn't have any problem.
Apr 25	comment	Can animals, like monkeys, be homosexual? its likely they saw right. many animals have been shown to exhibit homosexual behavior. en.wikipedia.org/wiki/Homosexual_behavior_in_animals
Apr 24	comment	Results of a complete DNA sequencing - are they 100% reusable? coverage is an estimate of the number of times each individual base in the target sequence has been sequenced. so 30x coverage means you would have produced an assembled sequence where 30 sequencer outputs would contain an average base. the coverage needs to be so deep because the short sequences from the sequencer (a few hundred bases) there is some uncertainty in each sequence, errors in sequencing, and the resulting difficulty placing any given sequence. this paper might help:ncbi.nlm.nih.gov/pubmed/23393025
Apr 23	comment	Results of a complete DNA sequencing - are they 100% reusable? for many of the technologies in use today, 30x coverage can still be problematic. Should mention that the sequencers have biases which systematically give hard to interpret or easily misinterpretable data. but given this, the data could and should be reused if its a whole genome sequence.

Apr 23	comment	Why are there no wheeled animals? you're not so much a layman anymore ! :) good question.

Apr 23	comment	Why are there no wheeled animals? I think I would argue that there are serious issues in all three categories here. Maybe the anatomical arguments are less important than the evolutionary constraints. I guess that would be #1 for me since the anatomical argument is based on the idea that the anatomy of wheels are just too many adaptations away from what we have now. The inefficiencies of wheels make that evolutionary distance even greater.

Apr 18	comment	Why are there no wheeled animals? You are getting more clear with your argument for, but there is still a ways to go -I added some response to my answer here. Its a good exercise to think this through. Good one.

Apr 17	comment	Zombie Ant Fungus? yup - its more likely to be mediated entirely by biochemical/chemical signals in the ant's body, possibly targeted to the brain, but possibly not. this is one of the most interesting questions in biology today that is not cracked. Anyone read "Parasite Rex?"
