Why do motherhens so openly take in other species as if they were their own?
You have to keep in mind that chickens aren't all that bright. They'd rather waste resources caring for a child that isn't theirs than risk neglecting one that might be theirs. It's a chicken's way of
Why are steel surfaces relatively inhospitable to bacteria and other germs whereas stuff like acrylic are not?
I believe it has to do with the surface and how porous it is/isn't. Bacteria need tiny holes to hang out in (which also traps stuff they feed on), otherwise they get brushed away easily and there is l
Why can’t the cellular infrastructure that is in place to provide 3G and LTE just be used to create a giant WiFi network?
WiFi is not the same thing as a cellular network. This seems to be a common misconception, when I tell people that I have wireless broadband, because I can't get a landline, many people respond "oh, s
Why do video game developers still make games for last-generation consoles?
There is still a massive market in the previous generation consoles. You want to appeal to the widest audience as possible. While the Xbox one and ps4 have sold well, they are nowhere near the amount
why haven’t black people assimilated yet? (honest question. Seems like every other race/nationality, given a generation, fit right in.)
Dude Jim Crow laws were only repealed in 1965 and hardcore racism has only really died out recently. It's been a generation or two give it time goddamn.
Why people are so quick to overgeneralise behaviours of individuals to large groups when they disagree with their point of view?
> But slow to blame all Christians for the actions of one individual. They do. > But not so quick to blame all men for the actions of a few misogynists.
Why can’t we artificially inseminate endangered species like pandas and rhinos in order to raise their numbers?
Increasing their numbers doesn't solve any problems. They're being wiped out in the wild, through habitat destruction, poaching, etc. Having 'more to die' doesn't fix the 'to die' part.
Why are genetic disorders like trisomy 21 much more common than say, trisomy 19?
Most trisomies and other severe genetic defects are incompatible with life. The embryo never even reaches the fetus stage. It dies and is expelled in many cases even without the mother knowing she is
Why do we use implants for breast enlargement instead of something biological like stomache fat?
Fat is a living tissue. Transplants of living tissue are more expensive and have higher risk of complications. Implants are biologically inert and relatively easy to implant.
Why are all baby boomers being encouraged to be tested for hepatitis c? How could an entire generation be infected?
[Here](_URL_0_) is a good source if you want to read through it. But basically, baby boomers have a rate of Hep C infection five times higher than any other generation, and no one knows why. Since a p
