How long does it take for organisms to evolve?​

For reasons that are not completely clear, the data show the long-term dynamics of evolution to be quite slow." Across a broad range of species, the research found that for a major change to persist and for changes to accumulate, it took about one million years.

Explanation:A new species can evolve in as few as two generations, researchers have found, shattering the orthodox position that speciation is a process that occurs slowly over a long time.
