  • Topic:10- Evolution
  • Subject(s):Science
  • Days:20
  • Grade(s):10
Key Learning:

The theory of evolution is used to explain the diversity of life found on the Earth as well as to predict future changes in biodiversity.
Unit Essential Question(s):
 
 

How do environmental and genetic factors work together to cause evolutionary changes in an organism?
   
Concept: Natural Selection
SC.912.L.15.13  

Discuss Darwin's development of the theory of natural selection.

Discuss conditions for natural selection: overproduction of offspring, inherited variation, and struggle to survive resulting in differential reproductive success.

Examples of natural selection in action: bacterial resistance, insect resistance to pesticide, Galapagos finches.
Concept: Other Mechanisms of Evolution
SC.912.L.15.14   SC.912.L.15.15  

Discuss mechanisms of evolutionary change other than natural selection such as genetic drift and gene flow.

Describe how mutation and genetic recombination increase genetic variation.
Concept: Origin of Life
SC.912.L.15.8  

When teaching these topics, emphasize the scientific process.

Describe the scientific experiments that led to the explanations of the origin of life on Earth.
Lesson Essential Question(s):

What are the major causes and effects of natural selection?

What influence does natural selection have on the development of bacteria that are resistant to antibiotics?

 (A)

Lesson Essential Question(s):

How do mutation and genetic recombination impact genetic variation?

 (A)

What influence do genetic drift and gene flow have on evolutionary change?

 (A)

Lesson Essential Question(s):

What can we learn from the early theories of the origin of life?

 (A)

What experiments led to the development of the scientific explanation for the origin of life?

Vocabulary:

*natural selection

Vocabulary:

mechanism, punctuated equilibrium, adaptive radiation

Vocabulary:

biogenesis, primordial, endosymbiont

Concept: Evidence of Evolution
SC.912.L.15.1  

Evidence that supports the theory of evolution: fossil record, comparative anatomy, comparative embryology, biogeography, molecular biology and observed evolutionary change.

HOTS: Deductive reasoning or constructing support could be used to address the ET LEQ.
Concept: Hominid Evolution
SC.912.L.15.10  

Identify basic trends in hominid evolution from early ancestors 6 million years ago to modern humans including brain size, jaw size, language, and manufacture of tools.

HOTS: Deductive Reasoning, Constructing Support and Classifying/Categorizing could be used to demonstrate the ET LEQ.
Concept:

Classification

SC.912.L.15.4   SC.912.L.15.5   SC.912.L.15.6  

Describe the work of Linneaus.

Review the hierarchy of biological classification.

List examples of scientifc names.

Discuss the different criteria that have been used as a basis for classification.

HOTS: Classifying/Catergorizing or Deductive Reasoning could be used to address the ET.
Lesson Essential Question(s):

What are the essential components that support the scientific theory of evolution?

 (A)

What influence did speciation have on Darwin\'s development of the Theory of Evolution?

 (ET)

Lesson Essential Question(s):

What similarities and differences exist between neanderthals and humans?

 (A)

How do changes in hominids reflect evolution?

 (ET)

Lesson Essential Question(s):

How do scientists use new evidence to develop classification systems?

 (A)

How are evolutionary relationships useful in classifying organisms?

 (A)

How do we use characteristics to determine domain and kingdom?

 (A)

How does the classification system support the Theory of Evolution?

 (ET)

Vocabulary Report

  • *natural selection -

    the theory stating that every organism displays slight variations from other organisms of its kind, and the struggle for limited natural resources results in individuals with certain natural variations adapted to their specific environments

  • mechanism -

    the agency or means by which an effect is produced

  • binomial nomenclature -

    two-word system developed by Carolus Linnaeus to name species; first word identifies the genus of the organism, the second word is often a descriptive word that describes a characteristic of the organism.

  • biogenesis -

    the idea that living organisms come only from other living organisms

  • prehensile tail -

    long, muscular tail used as a fifth limb for grasping and wrapping around objects; characteristic of new world monkeys

  • analogous structures -

    structures that do not have a common evolutionary origin but are similar in function

  • phylogeny -

    evolutionary history of a species based on comparative relationships of structures and comparisons of modern life forms with fossils.

  • bipedal -

    ability to walk on two legs; leaves arms and hands free for other activities such as hunting, protecting young, and using tools

  • homologous structures -

    structures with common evolutionary origins; can be similar in arrangement, in function, or both

  • primordial -

    pertaining to the very beginning; also characteristic of early stage of development

  • punctuated equilibrium -

    the idea that periods of speciation occur relatively quickly with long periods of genetic equilibrium in between

  • vestigial structure -

    a structure in a present-day organism that no longer serves its natural purpose, but was probably useful to an ancestor

  • endosymbiont -

    an organism that lives within the cells or body of another organism

  • hominid -

    a group of bipedal primates that includes modern humans and their direct ancestors

  • adaptive radiation -

    divergent evolution in which ancestral species evolve into an array of species to fit a number of diverse habitats

  • specific epithet -

    the second word of a species name.

  • taxonomy -

    branch of biology that groups and names organisms based on studies of their shared characteristics; biologists who study taxonomy are called taxonomists.
