Some of the "branches" of a phylogenetic tree do not extend to the end. What do these lines represent?Extinct speciesConvergent speciesLineages that have not changedSpecies of unknown origin

Each branch point on a phylogenetic tree represents...Question 1Answera.The direct ancestor with different derived characteristics as the two lineages diverging from itb.A common ancestor of the two lineages diverging from itc.Always an extinct ancestor of the two lineages diverging from itd.Definitive proof that the two lineages diverging from it are related

On a branching diagram, what does the joining of twigs and branches represent?Multiple choice question.The pattern of common ancestryExtinctionDifferences in classification systems

Which of the following is true with respect to phylogenetic trees?Group of answer choicesthe mechanism driving speciation events is demonstratedeach node represents a common ancestor of 2 lineagesDNA sequences are the only data that can be used to construct a phylogentic treeall areas of the genome are equally useful for producing phylogentic trees

What is true regarding molecular and traditional analysis of phylogenies?Multiple choice question.Though there are differences between the two phylogenies, there is much agreement in the deep parts of the evolutionary tree.Most deep evolutionary relationships have been misunderstood until now.Molecular data is making morphological data obsolete; morphological analyses are being replaced.Molecular data are only useful to determine deep phylogenetic relationships.

For the phylogenetic tree located on the most left (with the letters lined up vertically), are the oldest species located on the left or right side of the tree?right sideleft side
