Answer :
The existence of evolutionary trends, such as increasing body sizes among horse species, is evidence that in particular environments, similar adaptations can be beneficial to more than one species
What are evolutionary trends ?
Evolving pattern a consistent shift in an adaptive direction, either in an evolutionary lineage or with respect to a specific feature, like shoot height. These patterns frequently show up in taxa that are unrelated. In the past, they were ascribed to orthogenesis; currently, orthoselection or the opposing hypothesis of species selection is used.
What patterns can we see in animal evolution?
Bilateral symmetry, real tissue and organ systems, a body cavity, a centralized nervous system, a fully functional digestive system, a segmented body plan, and a notochord are some of the major advances that happened within the animal kingdom.
