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

answer; /// i do believe the correct answer is (

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
