Answer:
The correct answer is option C) "comparison of DNA sequences of primates".
Explanation:
Before DNA analysis was available, biologists took different approaches to construct evolutionary trees among the species. However these approaches were inaccurate and produced variabilities, such as the one constructed by St. George Jackson based on spinal columns analysis and the other tree based on limb comparisons. Nowadays, comparison of DNA sequences is the most widely and accepted method to generate evolutionary trees for being a highly accurate and reliable source to establish common ancestors among species.
