Exam 5: Macroevolution: Processes of Vertebrate and Mammalian Evolution

The science that leads to the development of analogous structures is termed homoplasy.

The adaptive radiation of the mammals occurred mostly during the

Both the recognition species concept and the ecological species concept include natural selection as a factor in separating species from one another.

What are the features of the major models of speciation discussed in the text? Contrast the two schools of taxonomy: evolutionary systematics and cladistics.

Fossil and molecular evidence point to both gradual and rapid changes in the evolution of only animal species.

Therapods were a group of small- to medium-sized ground-living carnivorous dinosaurs.

Animals with a nerve cord along the back and gill slits during some developmental stage are called

The oldest fossils found to date are more than _____ years old.

Describe the principles of classification, including the differences in homologies, analogies, and homoplasy.

Discuss the fossil evidence and its importance on macroevolution and the understanding of speciation.

Vertebrates are subdivided into five classes.

Several species of very early hominins evolved over four million years; this is a clear example of:

In _________ the young are born in an extremely immature state and complete development in their mother's external pouch.

Structural similarities between species that are based on common function and not on common evolutionary descent are called

Explain how we connect to other species. What is the human place in the organic world?

Assigning fossil remains to a particular primate species

Explain the differences and similarities between microevolution and macroevolution, giving an example for each one.

Reptiles were the dominant land vertebrates during the Paleozoic.

Speciation refers to the process by which a new species evolves from an earlier species .

A phylogenetic tree _______, whereas a cladogram does not.
