1)pidgins monster


2)mother tongue


3)singing Neanderthal


4)social grooming​

Answer 1

Answer:

When significant evolutionary change occurs, the theory proposes that it is generally restricted to rare and geologically rapid events of branching speciation called cladogenesis.

Explanation:

Answer 2

Answer:

Social grooming

Explanation:

1) Grooming refers to behaviors involved in cleaning and maintaining body function and hygiene.

3)Social grooming, or allogrooming, is grooming of one individual by another.

4)This behavior is displayed by many different animals, including mammals, insects, fish, and birds (Britannica.com).

5) Social grooming is widespread among primates, where it serves a primarily social purpose, rather than a hygienic one (Henzi and Barrett, 1999).

6)Using Niko Tinbergen's "four questions" as a guide, we will discuss the evolution of primates and emergence of the social function of the behavior (phylogeny), the development of the behavior during a individual's lifetime (ontogeny), the specific biological and chemical processes and motivations responsible for the behavior (mechanism), and how the behavior increase the fitness of individuals, allowing for its continual selection in primates (adaptive value).

FINAL ANSWER - social grooming
