South Polar Bears The Arctic ice cap is melting away soon. Some (probably misguided) ecoactivists think it would be a good idea to safeguard certain indigenous species of the North Polar region (especially mammals) by migrating them to the opposite side of Earth: Antarctica. Let's assume they have the necessary fina... (more) |

How could state borders equal major watersheds? How can I explain, in a believable way of course, that country borders closely resemble drainage divides? They don't always match mountain ridges, which are natural borders "“ as are the rivers themselves in our world. In particular, with a point of divergence (POD) ±50 years around our calendar e...

How to know realistic fictional body measures? When creating humanoid races or species or just normal individuals, I sometimes want to describe a certain body measure and thus have to estimate a reasonable value. How do you do that? Are there algorithms, rules of thumb, charts, helpful 2D/3D modeling software? Actual adult humans can vary consid... (more) |

Karyotypes of partially interbreeding human races In a non-magical world where homo sapiens has evolved into several races or breeds (like dogs) or even species as in Q10102 and Q12190, that can interbreed for the most part, how can one model the chromosomes or genes to restrict the possible outcomes so each offspring clearly belongs to one (possibl...
