Change over time within an evolutionary lineage (phyletic change)..a)...
Explanation:
Phyletic change refers to the gradual evolution of a lineage over time. It is one of the many evolutionary processes that contribute to the diversification of life on earth. However, it is not the only important evolutionary process, and there are other mechanisms that can also lead to the origin of new species.
Phyletic change can occur in many ways, including genetic drift, natural selection, and gene flow. However, it rarely occurs without geographic separation of populations. When populations become isolated from one another, they can evolve independently and accumulate genetic differences over time. Eventually, these genetic differences can become so significant that the populations can no longer interbreed and are considered separate species.
While phyletic change can lead to the origin of new species, it is not the main means by which this occurs. Instead, speciation is a complex process that can be influenced by many factors, including geographic isolation, hybridization, and adaptive radiation. In fact, some researchers argue that the majority of new species arise through rapid bursts of speciation, rather than gradual phyletic change.
Therefore, while phyletic change is an important evolutionary process, it cannot account for the proliferation of species on its own. Instead, the origin of new species is a complex process that is influenced by a variety of factors, and phyletic change is just one of many mechanisms that contribute to this process.

Change over time within an evolutionary lineage (phyletic change)..a)...
Anagenesis, or phyletic evolution, is the accumulation of changes associated with the transformation of one species into another while cladogenesis or branching evolution involves the building of one or more new species from a parent species that continues to exist. Only cladogenesis can promote biological diversity by increasing the number of species.
