Cancer does hurt human's reproductive success; and evolution does fight with it.

comment Do white Australians have a distinct look?
@SonnyOrdell Yes, it is a general case and here is nothing special about Australians. Perhaps there is something special about Caucasian Australians but I doubt.

comment Do white Australians have a distinct look?
@nico I agree with your scrutiny, as the result is not cross-validated. However, it is not hard to design a test when people see two faces (single, not averaged) and two countries (and their task is to match them). I bet that even for nearby countries (e.g. Germany and France) one can guess with >50%.

comment How does the brain's energy consumption depend on mental activity?
Thanks, though I am far from making analogy with computer, especially when it comes to the information processed. Actually, the energy usage (at least - in principle) can be measured by heat generation, even if nothing is known about the process. "You assume in your question that a mathematician solving a differential equation needs higher mental activity than a child reading a book. Is this legitimated?" - hard to say; better to compare a mathematician during a few hour competition vs control.

comment What are the trajectories of flying insects?
@MartaCz-C: Abstraction sometimes helps (I am a physicists). And properties of the trajectory are very likely in a close relationship both to optimizing certain actions (avoiding predators, looking for prey, finding new habitat patch etc.) while being bounded by constrains (physiological, energy, ...).

comment How do cockroaches resist the effects of ionizing radiation?
While it's not my main topic I bet that (as I said) for all typical organic substances the shielding is ~mass/area. And as chitin has density of ~1.5g/cm^3 (ref) 1 cm of flesh is equivalent to ~7mm of chitin. So for radiation which is neither stopped nor transmitted by both, insects (unless they are extremely large) are less shielded. However, there may be some nuances and I think it makes I good question for physics.stackexchange.com.
