Answered

Why might researchers choose to use molecular data (such as ribosomal RNA sequences) rather than morphological data to study the evolutionary history of animals? A. Molecular data can be gathered in the lab, while morphological data must be gathered in the field. B. Molecular data can be used to give an estimate of the time since two groups split. C. Morphological changes usually do not result from molecular changes. D. Some phyla vary too widely in morphological characteristics to be classified accurately.



Answer :

The correct option is (D) Some phyla vary too widely in morphological characteristics to be classified accurately.

What is the significance of studying the molecular evidence?

  • Adenine, thymine, cytosine, and guanine are the four nucleotides (base pairs) that make up genetic information in DNA (represented by the letters A, T, C, G).
  • The DNA code undergoes nucleotide alterations as a result of mutation throughout time. It is possible to track genetic evolution across time by comparing the DNA of various creatures.
  • In a piece of DNA, counting the amount of nucleotide changes between species reveals how long ago these species split from a common ancestor. The number of nucleotide changes will increase the more apart two species have evolved.
