comment Are there special constants in biology that define organism's morphology?
To give context to the question: I'm interested if there are some numerical patterns to gene expression during organism's development.

comment Are there specific features of birds that cats/small predators are attracted to?
Movement is definitely part of it. I noticed that my cat likes to chase dried cranberry more than a similar sized plastic ball or a rock. The cranberry bounces in a different way, or maybe it's the seeds rattling inside.

comment Why do we dream?
A couple comments: about 75% of dreaming occurs in REM, but REM is not a requirement for dreaming. The term for conscious control of dreaming is "lucid dreaming", and potentially "dream incubation" for intentionally dreaming about a certain thing

comment What percentage of possible proteins has been tested by human brain evolution?
By tested I meant transcribed and available

comment Is there a preferred sleeping position for humans?
By head direction I meant compass orientation like north or east

comment Do male animals visually perceive females as more/less attractive?
It would be interesting to know if an alpha primate male, while mating with all his females still shows stronger preference to some of them, and if so, what controls that attraction

comment Do marine deep sea life forms exhibit circadian rhythms? If so, what entrains them?
Do you remember the name of the article or a link?

comment What is it called when one human eye is seeing brighter color than the other?
I also noticed this phenomenon after laying on a mattress with one side of my head against the mattress. I don't recall which side had most brightness, but the answer sounds correct

Are you trying to understand if reptiles like lizards are descended from dinosaurs?

comment What naturally produced drug causes 'a tingleing euphoric rush'
It's most likely not a substance, but an activation of a certain brain region, in which case it would be a neurotransmitter. Potential candidates are serotonin , dopamine, norepinephrine and choline.

comment Do animals also dream?
There have been experiments with cats whose brains were leisioned to eliminate sleep paralysis. These cats exhibited behaviors like hunting I imaginary prey, grooming, etc. this was interpreted as a cat dreaming

comment How animals maintain their body shape after development to maturity?
The laymen book is "endless forms most beautiful" by Sean b. Carroll

comment Are human males and females more genetically different than members of other species?
If I understand your answer correctly, because most of the genes(that matter) are in the X chromosome, then selecting for a specific trait in females would also produce it in males, because it's most likely that the X chromosome would be involved. Is this correct?

comment Can songbirds mimic car alarm sounds?
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

comment Can any species be bred selectively/engineered to become as diverse looking as dogs?
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

comment Can any species be bred selectively/engineered to become as diverse looking as dogs?
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.
