Question
Chapter 26.5, Problem 4CC
Summary Introduction
To explain:
Why researchers testing whether flower shape (bilateral versus radial) affected
Introduction:
The flower shape when symmetric in one direction is known as bilateral symmetry and when the flower shape is symmetric in all directions then it is known as radial symmetry.

Suppose the phylogenetic species concept (PSC) were preferred over other species concepts, such as the BSC. What would be the implications for (a) discourse on the evolutionary mechanisms of speciation; (b) studies of species diversity in ecological communities; (c) estimates of species diversity on a worldwide basis; and (d) conservation practices under such legal frameworks as the U.S. Endangered Species Act?

Question: Summarize how new species can arise by explaining the differences between allopatric and sympatric isolation. Give a real example of when allopatric speciation has been observed and when sympatric speciation has been observed.
. WHAT IF? Do speciation rates in closely related cladesof flowering plants show that flower shape is correlatedwith the rate at which new species form or that flowershape is responsible for this rate? Explain.

Does the phylogeny shown above support the claim humans did not hybridize with Neanderthals in the past? How can you tell? b) Once nuclear DNA sequencing became fast and able to handle sequencing ancient DNA, living humans were found to have some Neanderthal genes. Is this finding clear evidence that some early modern humans did indeed hybridize with Neanderthals? Why? c) Did female H. sapiens hybridize with Neanderthal males to produce fertile offspring that then back-crossed with modern humans?

Island Subspecies Santa Cruz santacruzae Northern Chanel Islands Santa Rosa U. I. santarosae San Miguel U. I. littoralis San Nicolas U.I. dickeyi Southern Channel Islands San Clemente U.I. clementae Santa Catalina U.I. catalinae The island fox shares a common ancestor with the gray fox. Urocyon cinerecargenteus, which is found on the mainland. Both species have similar coloration and a diploid chromosome number of 66. One structural difference between the two species is the reduced size of the island fox, a feature known as dwarfism. The various island subspecies also differ from each other in size, number of tail vertebrae, and other characteristics The…arrow_forwardLet's Evaluate Fill in the blanks with the words below.

What are they? Does this species concept apply in all situations? Think of an example from nature where the biological species concept would NOT be that applicable. Which species concept would be better in this example? How does speciation occur? What environmental factors might contribute to speciation? Can an individual speciate? Use terminology for the two kinds of speciation we have learned about. What is “gene flow”? What does it mean if there is NO gene flow? Two groups of individuals are separated by either side of a canyon. One researcher found that they do not cross the canyon at any point. The group on the north side have fluffy tails and thicker coats, and they do not eat moss. The south side individuals eat moss almost exclusively, have a thin coat and tail, but otherwise are generally identical. When in the lab they mated successfully, and the offspring of that mating also mated…arrow_forward
