Students have asked these similar questions
How are shared ancestral characters and shared derived characters different? How is the concept of homology related to these concepts?
What is the difference between a phylogenetic tree and a cladogram?
What the difference between "homologous traits" and "analogous traits"?
What is the difference between "ancestral traits" and "derived traits"?
In the last lab while creating a phylogenetic tree using PAUP/CIPRES, Fagus grandifolia was
specified as the outgroup . Why is this step important?
If the outgroup is not specified, PAUP or CIPRES will produce an unrooted tree in which outgroup is not
connected to the rest of the tree by a common ancestor
If the outgroup is not specified, PAUP or CIPRES will produce an unrooted tree in which the outgroup might
not branch off prior to the common ancestor of the organisms under study
O If the outgroup is not specified, PAUP or CIIPRES will produce an unrooted tree. Unrooted trees do not
follow the Law of Parsimony
All options are incorrect

- What is speciation? List any two events that lead to speciation?arrow_forwardHow, specifically, is the concept of ALLOMETRY relevant to the phylogenetic position of Homo floresiensis? Because if allometry explains the anatomy of Homo floresiensis then we can conclude that it is not separate species but instead a member of our species. Although most mammals on islands go through a process of getting smaller, Homo floresiensis evolved from a smaller ancestor to be bigger, meaning that allometry is an important factor. Mutations in the allometry allele are associated with many of the characteristics of Homo floresiensis. Because Homo floresiensis is so much smaller than other members of the genus Homo, it is important to determine how shape changes associated with smaller size impacted the species. Because Homo floresiensis had both small- and large-bodied forms, variation within the species is in large part dictated by allometry.arrow_forwardWhat is the basis of using a molecular clock to determine when two species diverged from a common ancestor?arrow_forward
