Adaptations

Question 1

Optimality

Answer 1

crafting organisms that can meet the challenges of the environment
as efficiently or economically as possible

Question 1

Mutations

Answer 1

Random changes in the A’s, C’s, and T’s, and G’s, that makeup DNA

Question 2

Evolutionary Mismatch

Answer 2

When adaptations are “out-of-date” because the environment has
changed quickly, these traits are now maladaptive because they are
disadvantageous in the present environment.

Question 3

Byproduct

Answer 3

Traits or characteristics that don’t solve adaptive problems, don’t
have functional design, and don’t lead to reproductive success

Question 4

Divergence

Answer 4

Related species evolve different traits.

Question 5

Convergence

Answer 5

Unrelated species evolve similar traits

Question 6

Reverse engineering

Answer 6

Looking at all features of a trait in
order to deduce its function and to figure out what it has evolved to
do

Question 7

Comparative method

Answer 7

Involves comparing the traits of
different species to figure out what each has evolved to do

Question 8

Obligate Adaptations

Answer 8

fixed trait, doesn’t change with the environmen

Question 9

Facultative Adaptations

Answer 9

flexible trait, changes depending on the environment.
