Scientists notice structural similarities between fossils of a land animal and an aquatic organism. they know the similarities are not a result of the two organisms having to adapt to similar environments. what can they attribute the structural similarities to? a)convergent evolution b)common ancestry c)transitional evolution d)similar mating habits

Option A

Explanation: Convergent evolution can be defined as the evolution of similar features in the species of different lineage.

Convergent evolution creates analogous structures to have similar forms or function but are not related by ancestry.

They do not have common ancestry. Example: all the flying insects have evolved differently but have same feature of flying.

So, the correct answer is option A

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
