Question
Chapter 18, Problem 11SQ
Summary Introduction
To identify: The populations of organisms that are most likely to survive climate change via evolutionary adaptations.
Introduction: Environmental change is an essential part of life. It is responsible for the evolutionary changes. The population of organsisms which have high genetic variability and short lifetime may survive climate changes through evolutionary adaptations.

Applying your knowledge of genetics, natural selection and evolution, how is the positive response to global climate change possible? Is your answer supported by the information from the article “Can Evolution outrace Climate Change”? According to the authors of this article, what are the conditions necessary for an organism to evolve to accommodate climate change?
What factor results evolution of a species?
A) Genetic Drift
B) Gene Flow
C) Natural Selection
Climate change causes problems for organisms that have adapted
to their environments. Please list two problems that climate change
could cause which would prevent organisms from surviving in an
environment to which they are well adapted.
