Increasing specialization of structure and function among animals of the same class or order for survival in new and different environments is called "phylogeny".
<u>Option: B</u>
<u>Explanation:</u>
- The analysis of evolution, diversity and the inter-connection among individuals or groups of organisms like species is understood as phylogeny.
- First one to apply the term phylogeny was German Biologist Ernst Heinrich Haeckel.
- With the help of estimation techniques of phylogenetic, such relationships were explored to test identified heritable traits, like DNA sequences or morphology under a framework of evolution of those characteristics.
- The detailing of species, their naming and grouping is understood as taxonomy. It is abundantly guided by phylogenetics, but maintains a field isolation from the scientific and logical.
- Based on the taxonomy school the extent to which taxonomies rely on phylogenies.
Answer:
C. The songs will become more similar to each other.
Explanation:
To answer this question, first, you need to remember that both populations belong to the same species, so they can mate because there is no reproductive barrier. The only limiting physical factor impeding individuals of both groups to cross was the piece of land before the land got wetter. So once populations got together, individuals can easily mate.
One population´s males exhibit a courtship song that slightly differs from the one of the other group. This difference has a genetic basis. But females hardly notice the difference. All of them prefer loud frogs to quieter frogs, independently of the population to which they belong.
So when the two populations get together, individuals get mixed. Females do not recognize males of their group, and during the breeding season, all females will mate the most with louder males of any of the population. So females from population A might mate with males from population B, and females from population B might mate with males from population A. So after mating season, there is also a genetic mixture between populations.
The new generations will carry elements of both genotypes. So males´ songs will be even more similar to each other. Songs will become more similar to each other because individuals of both populations are mixed and mated, and their genes intercrossed, producing new individuals with genes of both populations.
Formation of a hypothesis.
<span>Research method is always used to answer every scientific inquiry and in gaining evidential data or knowledge. The scientific method has the following process or at least undergoes the process of
1. Observation</span>
2. Hypothesis
3. Experimentation
4. Interpretation of data
5. Evaluating the data
6. Passing and recording the data
<span>These steps are crucial and the empirical data that these scientists obtain are very important to keep that is why research paper, thesis and dissertations exists.<span> </span></span>
