| Apr 13, 2019 at 21:54 | comment | added | Joe | @Foosic17, because of the mountains? | |
| Apr 13, 2019 at 17:40 | comment | added | Foosic17 | @Joe Probably something like Central America | |

| Apr 12, 2019 at 14:44 | comment | added | TheDyingOfLight | You are overlooking one crucial aspect. Your Nothorses are supposed to be similar in function to horses. Horses are really good swimmers. So they wouldn´t care if there is a landbrige or not, they would just swim over. The landbrige would not matter at all for them. | |

| Apr 11, 2019 at 19:49 | comment | added | reirab | @AlexP Agreed. Middle of the temperate zone in the Eastern U.S. here and our seasonal variation is around -20 C to +40 C. In the Northern plains states in the U.S. (45 deg North just like you,) it's more like -40 C to +40 C. I guess that's 'mild' variation compared to, say, Mercury, but it's not particularly mild for Earth. | |
| Apr 11, 2019 at 11:16 | comment | added | AlexP | @On our Earth temperate regions vary between pretty mild (but still significant) variations between seasons (what's called oceanic temperate) to very harsh variations between seasons (continental temperate). For example, Bucharest is situated at 45 degrees north, in the middle of the temperate band, and we have a temperature range from -15 centigrade (winter minimum) to +40 (summer maximum). If other worlds have a different kind of temperate climate then I believe this should be mentioned. | |
| Apr 11, 2019 at 11:02 | comment | added | Konrad Rudolph | @AlexP First definition on Google: “relating to or denoting a region or climate characterized by mild temperatures” — Nothing about seasons. On our Earth temperate climate is correlated with the existence of (mild) seasonal variation but there’s no rule, even in a science-based Universe, why this should be a universal requirement. | |

| Apr 10, 2019 at 19:04 | comment | added | Chuck Ramirez | I don't think food or predation are good answers because they just displace the question to a different level of the food chain, i.e. the question simply becomes why food or predators are unable to cross? | |

| Apr 10, 2019 at 13:17 | comment | added | genesis | Wait...I thought a landbridge is just a bridge made of land, ie a small strip of land, isn't it? Reading some of the other answers I am now confused. They seem to assume a man-made bridge. | |

| Apr 10, 2019 at 12:52 | comment | added | AlexP | "Temperate grassland" and "lack of seasons" are mutually incompatible. ("Temperate" means the standard four seasons.) And there are many kinds of terrain which horses cannot easily traverse; for example deserts (horses need an lot of water), terrain infested with the tsetse fly, dense forests, steep mountains, etc. To give an example, horses never crossed from the Eurasian grasslands into the African savannah until they were brought there by humans. | |
