This West Indian manatee (Trichechus manatus) is an aquaticmammal. Like amphibians and reptiles, mammals are tetrapods (vertebrates with four limbs). Explain why manatees areconsidered tetrapods even though they lack hind limbs, andsuggest traits that manatees likely share with leopards andother mammals (see Figure 26.12b). Discuss how early members of the manatee lineage might have differed from today’smanatees.

Evolutionary lineages

An evolutionary lineage is a series of populations of organisms that descend from a common ancestor. Each species in the lineage is the direct consequence of evolutionary change from a common ancestor. A phylogenetic tree is generally used to display lineages visually. Lineages are components of the phylogenetic tree of life. Molecular systematics procedures are widely used to predict lineages.
