D identity of the phylogenetic kingdom or domain in which these phenomena occur. There is absence of intermediate fossils. What is Punctuated equilibrium model.

If two species are able to mate and produce an offspring which can mate with itself but which is unable to mate with its parents species then this can best be described as an example of 1 point a. 18 Which of the following would best be described as a case of speciation in sympatry. 15 The origin of a new plant species by hybridization coupled with accidents during cell.

A relative locations of two populations as speciation occurs. Arctic cultures lived in igloos People of great plains lived in round large homes made from dirt Iroquois League lived in wigwams The Southeast. Redheaded females in a population will only breed with red-headed males.

E the ploidy of the two populations as speciation occurs. The punctuated equilibrium model of evolution can be described as Species that accumulate their unique features rapidly then change little for the duration of the species. Speciation by polyploidy D.

The tempo or speed of speciation varies. Before the Isthmus of Panama joined north and south America there was just ocean there that contained 15 different shrimp species. After this lengthy periods of stasis or.

Species steadily diverge from one another. From the intersection of these two premises follows the prediction that reproductive isolation can evolve on ecological time-scales. B an error in mitosis.
