10. answer the question please in the picture Historically, whales and hippos have been classified in different orders: Cetacea and Artiodactyla,respectively. Recent molecular evidence, however, indicates that whales' closest living relatives arehippos. This has caused some zoologists to lump the two orders together into a single clade, theCetartiodactyla. However, it remains unclear whether the whale lineage diverged from the hippolineage before or after other members of Order Artiodactyla diverged. The cladograms below showthese two possibilities.Considering only whales and hippos, which cladogram shows these two groups positioned in thesame clade?"Within" Phylogenetic Tree"Without" Phylogenetic TreeWhalesWhalesHipposHipposOtherPigsartiodactylsOtherPigsartiodactylsO The "without" phylogenetic treeO The "within" phylogenetic tree

An evolutionary tree that depicts species' ancestral relationships is known as a cladogram. A scientist investigating phylogenetic systematics uses a cladogram to depict the groups of organisms being studied, their relationships, and their most common ancestors. A cladogram might be quite simple, comparing only a few groups of creatures, or it can be extremely complex, incorporating all known forms of life. A cladogram is made up of lines that branch out in various directions before ending at a clade, which is a group of organisms that have a common ancestor. Traits used to construct a cladogram can be roughly categorized as either molecular (DNA, RNA, or other genetic information) or morphological (warm-blooded, notochord, unicellular, synapsid skull, etc).It is specifically stated in the question that molecular evolutionary studies are the primary reason for keeping whales and hippos together in the same category. Maybe, their phylogenetic traits or organ studies show completely different behaviour. As a result, comparative evolutionary studies at molecular levels are carried out and the entire DNA is sequenced. Based on this evidence, it is assumed that whales and hippos share a common ancestor from whom they evolved, and despite their differences in organismic structure and adaptations, they are put in the same group for comparative evolutionary studies. The figure contrasts the origins of the whale lineage "within the artiodactyls" and "without the artiodactyls." Pigs are more closely related to whales than hippos in the "within" phylogenetic tree, whereas in the "without" phylogenetic tree, pigs are more closely related to hippos than are whales. The "without" phylogenetic tree is more consistent with molecular evidence than the "within" phylogenetic tree. Pigs are more distantly connected to hippos in the "without" phylogenetic tree than in the "within" one. Pigs are more closely linked to hippos than whales in the "without" phylogenetic tree. In the "within" phylogenetic tree, all artiodactyls (even-toed ungulates), including hippos, are more closely related to each other than any are to the whales. Hence, the correct option is "The without Phylogenetic Tree" because this cladogram shows that the whales and hippos are positioned in the same clade.
