Thanks, that bird does imitate car alarm, but I was really surprised at the chainsaw sound

comment What parts of the brain are involved in regulating blood pressure in mammals?
Thanks, vasopressin does appear to affect blood pressure a bit in healthy individuals. There is a duplicate mention of blood pressure in the part of the article that deals with nervous system, but I'm not sure if this is the same or different effect

Interesting, I didn't know there were so many rabbits. It would be interesting to know if the genes for "floppy ears" are similar between dogs and rabbits

Great answer, from your first link, it appears that dogs have smaller number of genes that strongly morphology, while other organisms, like humans have larger number of genes that have only mild to moderate effect

comment What determined the evolution of different faces in humans?
I've read that penguins are also pretty good at identifying family members(visually and/or vocally) amongst hundreds of other similar looking birds.

comment Do cockroaches eat their shells after moulting?
I have read that spiders eat their webs to re-spin them somewhere else. Eating a shell Might be some form of recycling

comment Does brain activity generate heat gradients in the brain?
I've re-read the article and it actually mentions that heat repels the axon growth(text under the photo). This is indeed not an answer I was anticipating.
