wha does "geograpical causes" mean?
Geographic isolation is most likely caused by physical barriers such as mountains, rivers, or oceans that prevent populations from interbreeding. These barriers can lead to the evolution of new species due to the lack of gene flow between the isolated populations over time.
Geographic isolation, where physical barriers prevent gene flow between populations, can cause reproductive isolation. This can lead to genetic differences accumulating over time, ultimately resulting in the development of separate species.
They benefited from it because rich river valleys such as the Huang He, China has deserts, the Himalaya, Tibetan Plateau, and the Tian Shan mountains on the west. The bad things are that the rivers cause a lot of floods and because the dam will cause some land areas to be submerged and people in rural areas to be relocated.
Living on an island can be dangerous due to the risk of natural disasters such as hurricanes, tsunamis, or volcanic eruptions that can cause widespread destruction. Limited access to resources and medical facilities can also pose a danger in emergencies. Additionally, isolation and vulnerability to climate change effects like rising sea levels can threaten the sustainability of island communities.
The theme of geography that deals with how people cause places to change is called human-environment interaction. It explores the ways in which human activities impact the physical environment and how the environment, in turn, shapes human societies. This theme emphasizes the dynamic relationship between humans and their surroundings.
It prevents the two populations from interbreeding. :) -Apex-

The central idea here is that when populations are geographically separated, they will diverge from one another, both in the way they look and genetically. These changes might occur by natural selection or by random chance (i.e., genetic drift), and in both cases result in reproductive isolation.
it prevents gene flow between populations
People who may carry disease may be put into 'isolation'.

Any factor that in nature prevents interbreeding between individuals of the same species or of closely related species, for example geographic separation is itself a reproductive isolation because is a factor that prevents interbreeding. -extinction of one species -production of infertile offspring -development of physical differences
Long term isolation can cause new species to form if the isolation has been over a very long time.
One cause of speciation is reproductive isolation or the separation of the population of a species from other populations so that it can change without keep getting mixed with other populations( and therefore becoming identical to other populations).
Being shipwrecked on a desert island would do it.
It is possible that ADHD meds can cause feelings of isolation since they work to improve focus. If you have too deep of a focus, you might feel cut off from others.
