Purpose
This lab aims at determining what would happen if a species of lizards within a population were suddenly split into two groups created by a physical barrier like canyon resulting from an earthquake.
Introduction
Both recognition of members of the same species and differentiation of one species from another, animals use appearance. However, not all members of a species look the same (Anderson, 2009). The process by which one species splits into two species is referred to as speciation. The interruption of gene flow among populations facilitates speciation. Speciation takes place when a species of a population experiences a natural disturbance such as an earthquake. The natural disturbance results in displacement of a species from one location to another. The displaced species adapts to the new area and changes creating a distinct population. A particular species evolve in different ways to produce two distinct populations. These ways include the creation of physical barriers (Dieckmann, 2004).
Hypothesis
Suddenly splitting of a species of lizards within a population into two groups by a barrier created by an earthquake would result in the evolution of new species.
Methods
The research gets information from secondary sources. These are the documented sources that have relevant information on speciation.
Results/Outcome
When lizards of the same species are suddenly split into two by a physical barrier, a new population that is diverse from the original species is formed. These evolved species become progressively more different so much so that they cannot interbreed (Dieckmann, 2004).
Discussion/Analysis
The result of the research is as stipulated in the hypothesis. Establishment of gene flow barrier results in daughter populations diverging genetically caused by evolutionary agents. However, geographical isolation may not necessarily result in reproductive incompatibility. This is evidenced by American and European sycamores (Fielding, 2014).
Conclusion
Speciation of animals is significantly affected by the creation of a physical barrier. As the population that is displaced to a new location develops adaptive traits, evolution takes place thereby forming new species.
