Document Summary

Convergence of dna can occur too: convergence in molecular level cam lead to misinterpretation. One group might be similar to another in terms of dna but evolutionary closer to another. Short interspersed nuclear elements (sine) data overwhelm astragalus datum.

Cryptic species (not obvious morphological info: many species are not easily distinguished by morphology, animal and plant parts also are sometimes not easily identified, most diverse parts of the world are also the least known.
