Answer:

Evolutionary biology illustrates both the pattern and processes. The processes of evolution are natural selection and other mechanisms, which modifies the genetic structure of the populations. These processes result in evolutionary patterns, that is, the products generated by evolution with time.  

Phylogeny refers to the evolutionary history of a species or a group of species. In order to redevelop phylogeny, the scientists use systematics, that is, an analytical method to categorize the diversity and finding the evolutionary associations between the extinct and the living species.  

The evidence used to redevelop phylogenies can be attained from the fossil record and from the biochemical, morphological, and genetic similarities between the species. The scientists are functioning to develop a universal tree of all life, which will get refined with the gathering of new information.

Which of the following makes the statement FALSE? In the alternation of generations life cycle, the generations that alternate A
sammy [17]

Answer:

The false statement is option C. Directly develop into one another as parts of the same individual.

Explanation:

Alternation of generations is one of the type of the life cycle which is common in land plants and some of the alga species change n between haploid and diploid generation alternatively of an individual. It is presented in the plants only as in animals both haploid and diploid cell present in every generation.

In the alternation of generation, generation does not directly develop into each other as part of the particular individual.

Thus, the correct answer is option C. Directly develop into one another as parts of the same individual.
