Answer:

A) allopatric speciation

Explanation:

  • Allopatric speciation is a type of speciation that is caused due to geographical isolation that results in the separation of the population of the same species that once inhabited the same geographical area.
  • Due to this geographic separation, the species become so isolated that no more gene flow occurs between the two species and therefore, with time new species get formed.
  • The various geographic changes that can contribute to the separation of the two species can be - formation of mountains, islands, water bodies, glaciers, etc.
  • The populations that get separated due to the geographic barriers are subjected to different selective pressures and hence, speciation occurs.

How do scientists decide when to change or modify their understanding of a particular topic?​
Natali5045456 [20]

Answer:

they carry out experiments to understand it

Explanation:

Scientists raise hypotheses which are tested by experiments made under controlled conditions in order to explain a particular topic. When a hypothesis is confirmed by the experimental data, the evidence obtained from this experiment provides the basis to increase the scientific knowledge about a particular issue. In consequence, experimentation can be considered as a critical step in the scientific method and research aims to advance knowledge of a particular phenomenon by confirming a hypothesis, which must be testable (i.e. verifiable as a result of further experimentations).
