Midterm 1 (Part 3)

Question 1

acclimation?

Answer 1

proccess where individal adjusts to change in environment, rapid and reversible

Question 2

Steps of comparative method

Answer 2

Pattern, hypothesize, prediction, test, inference

Question 3

example of acclimation?

Answer 3

at high altitudes increased RBC count, hemoglobin,deeper breaths, etc.

Question 4

How to demonstrate a trait is adaptive?

Answer 4

determine its function and show that function increases fitness in environment

Question 5

What is the comparative method

Answer 5

seeks to correlate differences among populations or species with variation in selective agent

Question 6

What is adaptation?

Answer 6

A heritable process that allows individuals to preform a function that enhances survival, the evolutionary process that croduces adaptations

Question 7

Exaption example?

Answer 7

feathers on birds didnt evolve for flight, were there long before flight

Question 8

What is a reciprocal transplant?

Answer 8

fitness of individuals is quantified in each of two enviroments, local adaptation shows prediction

Question 9

What is adaptation not?

Answer 9

no reqirements that trait originally evolved by natural selection

Question 10

what is an adaptionist fairy tale?

Answer 10

unsupported explanantion for value of phenotype, under assumption that most traits are evolved via natural selection

Question 11

What are exaptations?

Answer 11

structured that are currently adaptations but evolved in different context, were later made for fitness enhancing function, adaptations that arose after change in function
