comment How did this spider evolve to mimic exactly a human face and arms?
And to note: this is all rather hypothetical, of course. It's hard to get a direct answer to any evolutionary/ecological question, hence there's so much debate.

comment How did this spider evolve to mimic exactly a human face and arms?
@terdon Absolutely, we do see faces everywhere. But we use a colon and parenthesis because they look like a face. My whole argument is that indeed there's antroporphism, but animals take advantage of that all the time. As for that spider, it is not trying to imitate a human face in particular. Rather, having a back that looks like a scary face may help with larger animals.

@terdon What about the example with the moths in London who changed their wing color to a darker shade when the industrial revolution covered the city in ashes? I think human activity can provide stable selection in many cases.

Not sure. Could be both, I think, since bigger predators may inadvertently crush the spider or use it at play. The scary face could stop them from doing that.

comment Strange behavior of a DNA gel
Yeah, I threw out the old gel but I ran a new one at a higher voltage and shorter time. It worked. I'll check your theory when I get some free time

comment Strange behavior of a DNA gel
I looked it up and the website does say sybr safe runs away from migrating DNA. I might have been off with the timing and this fits, thanks.

comment How long can I store autoclaved disposables and reagents?
Great, so from what I gather: sealed autoclaved plastics can be used even after a year of storage. It is safe to presume buffers are good for a week. That pretty much answers my question. I think it outlined clearly in the answer for future reference.

comment Least painful way to die
Part of the problem is: how do you know when an animal is suffering or in pain? Maybe looking into pain management research that uses animal models would be informative.

Thanks, I was asking specifically for plastics and buffers, such as PBS. No medium or antibiotics.

You suggest an interesting idea, but what's the question?

comment A program for cell motility assessment with a batch process function?
I don't know of a specific program but the MATLAB file exchange is likely to have scripts for that purpose. It may also help to migrate this to StackOverflow
