New inheritable characteristics can result from a variety of gene combinations created by mutation and sorting and recombining of genes during meiosis and fertililzation.

 

 

Mutations are random chance events that, when occurring in sex cells, are passed on to offspring

 

                                                           

Topic:

Evolution: Change over time
 
Natural Selection explains the fossil record of ancient life forms as well as molecular and structural similarities among diverse species.

 

 

Variation leads to adaptive advantages which lead to survival of a species that will reproduce and pass the advantageous genes on to offspring.

 

 

Evolution does not necessitate progress in any set direction

 

Examples:

 

 

 

 

Radioactive Decay model lab activity.

Adaptations of Birds lab activity.

Allelic Frequencies and Natural Selection lab simulation.

“Beaks of Finches” NYS lab activity.

 

Adaptation of bacteria and the role of antibiotics.

Peppered Moth example /discussion.

 

 

 

 

 

 

Enduring Understanding (s): All organisms within a species have variations which give some of them an advantage.  These advantages allow the organisms to survive, reproduce, and pass those advantageous genes on to their offspring.  In this way, the characteristics of a species changes over time.

 

 

Essential Question (s):  1. If our country has the best medicine in the world, then why do we also have the deadliest bacteria and viruses?   2. Why would doctors try to not always give the same patient the same antibiotic, and instead rotate the use of several antibiotics, if the first one is working great?
