Populations and Evolution


March 20 2017
QFD: Be not afraid of life. Believe that life is worth living, and your belief will help create the fact.
Essential question of the Day : Analyze why populations are important to study in terms of evolution
This weeks learning objective : HS LS 4-3 Construct an explanation based on evidence for how natural selection leads to adaptation of populations.
Learning target : Students will take notes and view a clip that reveals information about Hardy Weinberg and population genetics
1) notes
2) problems Google classroom

HW : finish 3 problems

QFD: It’s never too late to be what you might have been.George Eliot
Essential question of the day : Analyze various adaptations that organisms have are advantageous for survival
This weeks learning objective : HS LS 4-3 Construct an explanation based on evidence for how natural selection leads to adaptation of populations.

Learning target : Students will solve problems involving hardy Weinberg formula by the end of the period
1) hardy Weinberg problems day 2
Hw : finish all problems

1) Genetic drift – a change in allele frequency due to random chance
Causes a loss of diversity
Affects small populations.. leads to a bottleneck ( drastic reduction in the number of species small populations can lead to a new population called the founder affect
2) Gene flow – occurs when populations join new populations and reproduce and increases the chances of a different species evolving ( liger) (Mule) less likely a species will be able to adapt or reproduce
3) Mutations – leads to genetic variation needed for evolution to occur
4) Sexual Selection selects traits to improve the species and for mating success’
5) Natural Selection selects traits most advantageous for survival
***Mechanisms of change – (mutations, Migration, genetic drift and natural selection)
6) co-evolution is used to describe cases where two (or more) species reciprocally affect each other’s evolution. Co-evolution is likely to happen when different species have close ecological interactions with one another. These ecological relationships include:
Predator/prey and parasite/host
Competitive species
Mutualistic species

QFD: a single act of kindness throws out roots in all directions, and the roots spring up and make new trees.Amelia Earhart
Essential question of the Day : Name and describe 3 ways in which some organisms have adapted to their environment and why these changes are significant for survival
This weeks learning objective : HS LS 4-3 Construct an explanation based on evidence for how natural selection leads to adaptation of populations.

Learning target : Students will complete a drawing that illustrates the findings of Charles Darwin , adaptation, and an example of survival of the fittest
1) quiz Hardy Weinberg

March 23 2017
QFD: Creativity requires the courage to let go of certainties.
Essential question of the Day : analyze why populations of animals change over time which aspect of evolution are most important to prove the theory of evolution
This weeks learning objective : HS LS 4-3 Construct an explanation based on evidence for how natural selection leads to adaptation of populations.

Learning target : Students will complete a test that reveals information about evolution , and adaptations regarding the theory of evolution by the end of the period
1) test due

QFD: Joy is a net of love in which you can catch souls. Mother Teresa
Essential question of the day : What adaptations do humans possess?
This weeks learning objective : HS LS 4-3 Construct an explanation based on evidence for how natural selection leads to adaptation of populations.
HS LS 4-2 Construct an explanation based on evidence that the process of evolution primarily results from four factors: (1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited resources, and (4) the proliferation of those organisms that are better able to survive and reproduce in the environment.
Learning target : Students will complete a handout concerning the evolution of size by the end of the period
1) dogs decoded
2) handout due on way out of class
