Answer:
The correct answer is - allopatric speciation.
Explanation:
The isolation of two populations of the same species from one another due to the geographic changes this type of speciation or isolation known as allopatric speciation.
Speciation is the slow process in which the preexisting population of one species evolved to new species. Allopatric speciation, also known as vicariant speciation or geographic speciation,
Thus, the correct answer is - allopatric speciation.
Genetic variations of traits in a population increase or decrease some individuals' probability of surviving and reproducing in a specific environment. Natural selection leads to the predominance of certain traits in a population and the suppression of others.

Answer:
Control environment is the most important procedures for getting good results.
Explanation:
The control environment for an experiment is the essential part for getting good results. In control environment, there is no or less chances of infestation from the external environment which can cause the results of the data more acceptable. So the scientists prefers laboratory for performing experiment as compared to outer environment. So in my opinion for getting better results, the control environment is the most necessary experimental procedure.
Yes, for getting better results I think there is a step that could have been added to the procedure is to follow the international standard procedures for taking the readings by the experimenter.
