Match the correct label to locations A, B and C on the figure below. Evolutionary history, or phylogeny, is represented visually by a phylogenetic tree. Trees have a common structure, with a root, nodes, and branches. To determine evolutionary relationships among living or extinct organisms, consider the most recent common ancestors. Lizard C: Natural selection leads to new species or groups of species. Eu Jin Chew/Dreamstime.com Crocodile B: This is the common ancestor of all organisms on the tree. Infographic 16.10 Dinion for Channing World Third Edition Gert Vrey/Dreamstime.com Dinosaur (extinct) Time musk/Alamy Bird Danita Delimont/Alamy A: This is the last common ancestor of the organisms above this point in the tree (in this case, dinosaurs and birds).

Phylogenetic trees are a type of model that can be used to show how organisms are related through common ancestry. The phylogenetic tree model represents nodes numbered 1 through 8. Using evidence from the phylogenetic tree determine which species would be MOST closely related to the species on branch C? Question options: The species on Branch A is most closely related to the species on branch C because they share the most recent common ancestor at node 1. The species on Branch B is most closely related to the species on branch C because they share the greatest number of common +ancestors. The species on Branch A & B are both most closely related to the species on branch C because they share the most most recent common ancestor at node 2. The species on Branches F, G, H, and I are all equally related to the species on branch C because they all split from a common ancestor at the same time which is illustrated by having nodes 2 and 7 at the…

What are potential applications of cladistics and phylogenetics? Select all that apply. Assess the relatedness of different species and genera within a family of organisms Predict pathogen-host associations and potential disease risk in target populations Correlate evolutionary divergences among a species with the behavior and dispersal patterns of existing populations Assess the diversity of target species or groups for conservation efforts
