Question

Q2. Recall your experiences with the fossil record in the Predicting Patterns exercise. Which of the following statements best describes the relationship between traits shared among species and the order in which the traits appear in the fossil record? (Hint: Traits appearing earlier in the fossil record are older, more ancestral traits, and those appearing later in the fossil record are newer, more recent traits.) Traits that are more widespread across distantly related species appear earlier in the fossil record. Traits that are more widespread across distantly related species appear later in the fossil record. Trait loss (i.e., trait disappearance) occurs earlier in the fossil record. Traits that are required for survival appear later in the fossil record. Submit Q3. A transitional species illustrates the descent with modification from an ancestral to a derived species or group. Which of the following statements MUST be true about a transitional species? The transitional species has some, but not all, of the traits that distinguish derived from ancestral species. Derived species outcompeted the transitional species for resources. The transitional species only existed for a short time. The transitional species did not co-occur with either ancestral or derived species. Submit
