Climatic changes resulted in a drying trend that has continued for the last 10,000 years. The extent to which a geological barrier can effectively isolate a population.
Geographical isolation is not a cause of speciation in an asexually reproducing organism because the population is self-pollinating and would be less prone to the factors which results from geographical isolation.
i dont know ask your teacher!!
Isolation such as geological can cause speciation because if one species where divided into two because of geological reasons, they're likely to change their behaviors and physical appearances to match that region.
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).
Normally, a population would split into two species by being physically isolated. However, if two groups of a species develops different breeding behaviors, the populations may continue do differentiate until they can be classed as separate species.
A factor that tends to cause species to change can be one of two things. It can be either climate change or an invasive species.
the factorthat might be responsible for the change is when the supply of food is more than the number of organism that are kept for feeding(under population
Their genes might mutate in different directions, so once their genes do not match up, a new species will be made.
