Lab 2 Phylogenetic trees are considered to be scientific hypotheses because they are testable and as data is collected they can be revised. True or False Phylogeny is the study of: the names of organisms convergent evolution speciation and evolutionary history fossils What term describes the basal internode at the bottom of a tree? branch node clade root The wings of bats, birds and bees is an example of convergence since the three groups did not inherit the characteristics from their common ancestor. True or False The more genetic differences between two species, the more distantly related those two species are. True or False Distantly related species have few genetic differences. True or False Look at the following table, which statement is correct? Taxa A, B, C, D, and E all share the derived trait for character 2, body form. Taxa D and C share the same derived trait for character 1, tegmen. Taxa A and B share the derived trait for character 1 (tegmen). Taxa E could be used as the outgroup because it possesses only ancestral traits. Taxa C possesses the ancestral trait for character 2, body form. Looking at the following tree, which statement is not true? Silverfishes are the outgroup. Butterflies and flies are more closely related than butterflies and beetles. Mantids are more closely related to beetles than cockroaches. Mantids and cockroaches form a monophyletic group. Mantids and cockroaches share the derived traits 1-1, 2-1, 7-1, 8-1, 12-1, 5-1, 9-1, and 11-1. Look at the following organisms from the taxonomic group Boltidae, why would "organisms" B and C be more closely related that B and A? B and C share more derived traits (threads, hex nuts, slotted head, and flat washers) than B and A (slotted head and threads). B and C share the same number of derived traits as B and A, so it is impossible to tell which relationship is closer from this information. B and A are more closely related than B and C. In Exercise 3, what is the name of the software used to perform your analysis? Phylogenetic Tree Constructor Bootstrap MEGA Pi CytB
