> > new species can arise from existing ones > doesn't exist yes, new species can arise from existing ones through a process called speciation where a population of organisms gradually evolves distinct characteristics over time, eventually becoming reproductively isolated from their ancestral species, thus forming a new species the foundation for new species lies in genetic variations within a population, which can arise from mutations and recombination environmental pressures can drive natural selection, favoring certain traits within the isolated population, leading to further divergence from the original species examples of speciation mechanisms: > allopatric speciation: when a population is separated by a geographical barrier like a river or mountain range.  > sympatric speciation: when new species arise within the same geographic area, often due to factors like sexual selection or ecological niche differentiation.
