- What type of features do you feel should be used to classify humans as a species? please answer shoert sentences onlySouth America North America Pacific Panama Caribbean Panama The cladogram above illustrates the relationships between four hypothetical species of oysters found along the coasts of western North America, western South America, and western (Pacific) and eastern (Caribbean) Panama. Use this tree to answer the following question. The two species from Panama are separated from one another by the Isthmus of Panama, the narrow land bridge connecting North and South America, which formed approximately 2.5 million years ago. Given the cladogram and the geographic information, is it likely that the Panamanian species arose through allopatric speciation? O No. While the Isthmus of Panama prevents gene flow between the two Panamanian oyster species, it has been a very long time since this barrier (the isthmus) formed. Yes, because the Caribbean Panamanian species is not related to any other oysters east of the Isthmus of Panama, but it is closely related to the Pacific Panamanian species nonian…Desciribe three facts that support the idea of organisms sharing a common ancestor.

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. A CDE F GH в I 2 |5 Using evidence from the phylogenetic tree determine which species would be MOST closely related to the species on branch C? O A. 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 same height. O B. 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. C. The species on Branch B is most closely related to the species on branch c because they share the greatest number of common +ancestors. D.
