In the Arrow/Midas Cichlid sympatric speciation hypothesis, the investigators had to investigate not only the biology and genetics of the species in question, but had to understand the geological history of the larger geological basin in which they occurred, AND the phylogeny of the populations. This is because .
A) They had to eliminate allopatric speciation and subsequent dispersal as a hypothesis.
B) Certain phylogenetic patterns could corroborate or reject the hypothesis of sympatric speciation.
C) Both answers are correct.

They had to eliminate allopatric speciation and subsequent dispersal as a hypothesis.

Explanation:

Allopatric speciation is produced by geographic speciation, thereby the genetic differences observed among organisms might be a consequence of this mechanism . The rejection of this hypothesis may imply sympatric speciation

surface mining destroys mountain tops, landscapes, forests and wildlife habitats. on top of that, it leads to soil erosion and destruction of agricultural land. the landscape changes can also disrupt river channels and streams, which leads to flooding. which, can destroy plant life and other animals as well.
