Question

According to cladistics, the best classification system is one that A. groups organisms based on similarities in morphology. B. conforms to traditional, Linnaean taxonomic practices. C. accurately reflects evolutionary history. D. shows a single evolutionary divergence of all prokaryotes from a eukaryotic ancestor. E. ignores secondary loss of characteristics inherited from a common ancestor.

Answer 1

Answer: C. Accurately reflects evolutionary history.

Step-by-step explanation:

Cladistics is a taxonomic system that seeks to group organisms according to their shared phylogeny or ancestry. An ancestor is identified and its descendants are traced in this classification system.

Certain characteristics of the ancestor such as his physical structure or form or his genetic traits are compared among descendants. The main method of classification is monophyletic, which is a system where the descendants are traced to only one ancestor.

Answer 2

C. accurately reflects evolutionary history.

Step-by-step explanation:

Cladistics refers to a biological classification system that involves the categorization of organisms based on shared traits. Organisms are typically grouped by how closely related they are and thus, cladistics can be used to trace ancestry back to shared common ancestors and the evolution of various characteristics.
