Question

Constructing phylogenies is not as simple as grouping organisms with similar characters together. Identify situations in which similar characters must be IGNORED.

-similar characters are derived
-similar characters evolved owing to convergent evolution
-similar characters evolved owing to gene flow
-similar characters are ancestral

Answer 1

similar characters evolved owing to convergent evolution; similar characters are ancestral

Step-by-step explanation:

Convergent evolution happens when two organisms belonging to different species, living at different times or different continents but the same biome develop analogous structures hence making them appear similar. The analogous structures were not present in the known ancestors of both groups.

Therefore convergent evolution is ignored during constructing phylogenies

Also similar characteristics that are ancestral are ignored.
