Answer:
True
Step-by-step explanation:
Generalized and specialized characteristics
This is wholly related to adaptive radiation as it as to do with a transition from generalized characteristics to specialized characteristics.
These two terminology express the adaptive potential of a specific trait.
Generalized trait
Are well adapted for diverse activities. An example is the ancestral characters.
Specialized trait
Are restricted to a few kind of activities. Am example is the derived characters.
Note: Only a generalized ancestor can give the flexible evolutionary background for a swift diversification.
Therfore, its TRUE to say "Only a generalized species with potential for adaptation to varied ecological niches can lead to all the later diversification and specialization of forms into particular ecological niches."
