species evolving form one to another to suit their environment

Detailed explanation-1: -Parallel evolution results in morphological similarities between two species. Because the environmental influences on the species are similar, both unrelated and distantly related species may undergo parallel evolution in equivalent habitats.
Detailed explanation-2: -’Parallel evolution’ occurs when independent species acquire similar characteristics while evolving together at the same time in the same ecospace. An example of parallel evolution is extinct browsing-horses and paleotheres.
Detailed explanation-3: -In evolutionary biology, convergent evolution is the process whereby organisms not closely related (not monophyletic), independently evolve similar traits as a result of having to adapt to similar environments or ecological niches.
Detailed explanation-4: -Parallel evolution is defined as ‘the independent occurrence of similar changes in groups with a common ancestry and because they had a common ancestry’ (Simpson, 1961, p. 103).
Detailed explanation-5: -Parallel evolution is the independent evolution of similar traits, starting from a similar ancestral condition due to similar environments or other evolutionary pressures. Frequently this is the situation in more closely related lineages, where several species respond to similar challenges in a similar way.
