Many features distinguish modern humans from the nonhuman apes. however, only two of these features define hominins. why? correct answer(s) drag appropriate answer(s) here the evolution of hominins involved several different changes that happened at different times. only two of these features evolved early enough to apply to all the hominins. proper taxonomic groups are always defined by the traits that are shared among members of the group but not found in closely related species. these two traits arose in the common ancestor of all hominins, but are not found in the nonhominin apes. proper taxonomic groups are always defined by the traits that all members of the group share.

Sea levels are rising due to climate change while increasing numbers of people are moving into coastal areas. to accommodate more people, there has been increased construction of beachfront resorts and condominiums. how is this impacting sea turtle numbers and biodiversity and why? a. the increased human population in coastal areas has meant that more food is available to the turtles (e.g., dropped food, waste from restaurants), which has led to an increase in the numbers and diversity of sea turtles. b. there has been very little change in the numbers and biodiversity of sea turtles because the planet is so vast that they can simply relocate to less crowded beaches. c. this has resulted in a decrease in numbers and diversity of sea turtles because it is restricting available nesting sites, and hence reproduction. d. this has resulted in an increase in numbers and diversity of sea turtles because people are around to protect them from natural predators.
