Human embryos have tails which become tail bones before birth. Tails also appear in fish, reptiles, amphibians, birds, and mammals Humans also have hair and produce milk to nourish the young, which is unique to mammals. What does this indicate? a close evolutionary connection between humans and many other mammals a very distant evolutionary connection between humans and many other mammals a very distant evolutionary connection between humans and many other reptiles a close evolutionary connection between humans and many other reptiles

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.
