Adaptation can be defined as how an organism makes a living.
true
Adaptation is a product of the present and a condition of the past.
false
Adaptation is the process of successful interaction between an organism and its environment.
true
Activity concerns how an organism moves around in its environment.
false
Dietary categories describe the primary foods consumed but not the entire range of foods.
true
Adaptions concern numerous variables which include: substrate preference, locomotion, social structure, and life history variables.
true
A niche is the ecological address of an organism.
false
By filling distinct adaptive niches, primate species can share the same habitat with reduced competition.
true
The environment is not merely ecological – it is also social!
true
Selection for adaptations associated with social skills has been essential to group-living for many primates.
truue
Orthogenesis is the misguided belief that evolution is goal-directed – it has a purpose.
true
Evolutionary theory provides adaptive explanations for primate variations that reveal that many human behaviors lie on a continuum with nonhuman primate adaptations.
true
Anthropological primatologists study nonhuman primates in order to gain insights on the human condition.
true
Initially Darwin was a Lamarckian but the “prevalence of variation in nature” did not support Lamarck’s evolutionary hypothesis.
true
Natural selection favors traits that enhance survivorship and reproductive success.
true
The range of variation within each population provides options when stressors favor some trait variants over other trait variants.
true
Natural selection is a “winner take all” process eliminating all of the genes of the unfavored from the gene-pool.
false
It is always correct to state that “something in the environment changes, so the organism got a new trait.”
false
The adaptive calling card of every primate is behavioral flexibility!
true
The challenge of defining nonhuman primate behaviors is worth the effort because it leads to an understanding of the cause of adaptive rule-breaking; ultimately, that information provides insights on human adaptation and adaptability!
