Question

If two organisms are in the same clade, what can you predict about their relationship?

Answer 1

If two organisms are present in the same clade, then it predicts that they have evolved from a common ancestor.

Further Explanation:

Cladistics is a process of classifying organisms based on their shared traits. This method is essential for grouping the closely related species, tracing the ancestors, and studying the evolution of various traits. While doing cladistics analysis, the first step deals with determining the polarity of the traits. It means to find out if a trait is derived or ancestral. Parsimony needs the pre-determination of the polarity of the traits. The construction of the cladogram is dependent on the principle of parsimony.  

Cladistics group organisms with similar features together and grouping is based on the common ancestry and shared derived traits. A clade is a set of organisms that include all the common ancestors with their descendants. In the case of small clades, there can be a probability that the same character condition repeatedly evolved under similar environmental pressures.

Answer 2

Answer: They share common ancestors

Explanation:

If two organism are in the same clade then they share common ancestor. If two organism have same common ancestors then it the two or more organism will have same features.

Clades can vary in size depending on the point on which it is being referred. Clade can also be defined as monophyletic group stem from a single point on the tree.
