Plantae protist and diatoms evolution

  1. Jan 22, 2010 #1
    Do similarities between plantae protist and diatoms arise from convergent or divergent evolution?

    3. The attempt at a solution

    I think they are from convergent evolution however I can't think of a reason why, I know they are paraphyltic on the evolution tree of life. It could be that environmental conditions could have caused this change thus it's convergent, they don't have shared derived trait with a common ancestor, and these new traits that have acquired are mere adaptations to environmental conditions. (this is my best attempt, any help is appreciated !)

    I think divergent is to do with with differences, and ultimately speciation, not with similarities.
    I may have misunderstood what your saying, but I hope this is of some help.
