Biology Unit 4.1: Mechanisms of Biological Evolution
My learning target: I can analyze and evaluate how natural selection produces change in populations, not individuals;
I
can analyze and evaluate how the elements of natural selection, including inherited variation, the potential of a population to
produce more offspring than can survive, and a finite supply of environmental resources, result in differential reproductive
success (7C); I can analyze and evaluate the relationship of natural selection to adaptation and to the development of diversity
in and among species; and I can analyze and evaluate the effects of other evolutionary mechanisms, including genetic drift, gene
flow, mutation, and recombination
My Look-Fors
I can define natural selection (7C)
I can explain what is meant by “survival of the fittest” (7C)
I can describe how genetic traits can affect the survival of a population (7C)
I can interpret a population graph to determine if a population is suited for
an environment (7C)
I can explain how environmental resources can affect the survival of a
population(7C)
I can analyze a scenario to determine how natural selection has affected the
population rather than an individual(7C)
I can analyze an population’s traits to determine how the trait affects the
reproductive success of the population(7E)
I can evaluate a group of similar organisms and use my knowledge of natural
selection to determine environmental factors that may have affected their
diversity(7C)
I can determine the result of directional selection, stabilizing selection and
disruptive selection (7C)
I can associate a graph to each of the selective pressures (directional
selection, stabilizing selection and disruptive selection) (7C)
I can decipher between a genetic trait and an acquired trait (7C)
I can explain how the number of offspring produced can affect the survival of
a population(7D)
I understand that resistance to insecticides and pesticides is a genetic trait
that is passed to offspring (7D)
I can analyze a population graph to determine the effectiveness of an
insecticide/pesticide (7D)
I can describe the effect that geographic isolation has on a gene pool (7E)
I can describe how adaptations such as mimicry and pesticide resistance can
affect a population (7E)
I can analyze how a specific adaptation may affect a population (7E)
I can explain how speciation occurs (7E)
I can evaluate a scenario and determine if speciation could occur (7E)
I can evaluate scenarios to determine situations that allow for highest rate of
natural selection AND lowest rate of natural selection (7E)
I can determine how beneficial or non-beneficial traits will affect frequencies
in a gene pool (7E)
I can explain genetic drift(7F)
I can describe how the Founder Effect influences the gene pool of a
population(7F)
I can identify traits that would be present in a population because of the
Founder Effect(7F)
I need to
work on
this
I am
unsure or
confused
about this
I already
understand
this
I can evaluate a scenario involving genetic drift and explain how it affects
genetic variation(7F)
I can explain what occurs during gene flow (7F)
I can describe the effect that gene flow has on genetic variation (7F)
I can evaluate population size and reproductive method in a population and
determine how they may affect gene frequency (7F)
PreAP only: I can use the Hardy-Weinberg equation to determine the allele
frequency in a population
PreAP only: Given a word problem, I can use the Hardy-Weinberg equation
to compare allele frequency in different populations
