Suppose a person does a study on tail length in skinks (a type of lizard). She measures the tail length of 10 Southeastern Five-lined Skinks and 10 Broad-headed Skinks. (Look these up on Google if you want to see what they look like!) The average tail length of her Southeastern Five-lined Skinks is 12.7 cm, and the average tail length of her Broad-headed Skinks is 13.2 cm. What can she conclude at this point?   Question 5 options:   Broad-headed Skinks, on average, have longer tails than Southeastern Five-lined Skinks   Southeastern Five-lined Skinks, on average, have longer tails than Broad-headed Skinks   She doesn't have an answer yet because she hasn't analyzed the tail length data   The two skink species most likely have the same average tail length

Animal Phylogeny

Cladistics is a method of biological classification where organisms are classified based on their ancestors and their relationship with them. It is defined as the concepts and methods for determining the branching patterns of evolution and evolutionary history. Some scientists, however, have preferred the term phylogenetic systematics or phylogenetic taxonomy to emphasize the reliance on a phylogeny for classification. It is the most common and accepted method for classifying organisms.
