Humans share several features with salamanders. Certain genes and proteins are nearly identical between the two species; both sp
ecies have four limbs with a similar skeletal structure; the species' early embryos are similar; and where the salamander has a functional tail, humans have a vestigial tailbone. In evolutionary terms, these are examples of _______
Homology refers to the presence of similar or shared body structures, body parts, gene sequences, proteins, etc. among various lineages. It represents divergent evolution of these lineages from a common ancestor.
Presence of various similar structures in human and salamander reflects the fact that these two species have shared a common ancestor during their evolution. The shared ancestry between human and salamander led to the presence of various homologous body parts and identical gene sequences in them.
You can imagine what would happen if 10,000 people a week were walking over these fragile hot-spring deposits. “The boardwalks are an amazing piece of construction that's a useful tool for resource protection, and visitor enjoyment and safety.
