Journal Entry:

What are some factors that lead to extinctions?

Learning Intentions

• We will learn how describe the two types of speciation, allopatric and sympatric.

• We will learn different types of reproductive isolation, such as temporal, behavioral, mechanical and gametic isolation.

• We will learn about causes extinctions and what can happen after an extinction event. 

• We will learn about the different origins of life on Earth models

Closing Task:

You can determine the type of speciation and evolution the animal you are researching has undergone.

Content Standards being covered:

Topics:
EVO-3.D Describe the conditions under which new species may arise.
EVO-3.E Describe the rate of evolution and speciation under different ecological conditions.
EVO-3.F Explain the processes and mechanisms that drive speciation.
EVO-3.G Describe factors that lead to the extinction of a population.
EVO-3.H Explain how the risk of extinction is affected by changes in the environment.
EVO-3.I Explain species diversity in an ecosystem as a function of speciation and extinction rates.
EVO-3.J Explain how extinction can make new environments available for adaptive radiation.
SYI-3.E Describe the scientific evidence that provides support for models of the origin of life on Earth.
