What is an adaptation?

Darwin proposed that new species evolve from ancestral forms by
A) the gradual accumulation of adaptations to changing environments.

B) the inheritance of acquired adaptations to the environment.

C) the accumulation of mutations.

D) the exponential growth of populations.

Learning Intentions

• We will learn about evidences that scientists have discovered since Darwin that support his theories by watching "What Darwin Never Knew" video.

• We will learn the purpose of a phylogenetic tree or cladogram that represent an evolutionary history

• We will learn evidences for common ancestry for eukaryotes.  

Closing Task:

You can create and analyze cladograms to show evolutionary relationships between organisms.

Content Standards being covered:

Topics:
EVO-1.M Describe the types of data that provide evidence for evolution.
EVO-1.N Explain how morphological, biochemical and geological data provide evidence that organisms have changed over time.
EVO-2.B Describe the fundamental molecular and cellular features shared across all domains of life, which provide evidence of common ancestry.
EVO-3.B Describe the types of evidence that can be used to infer an evolutionary relationship.
EVO-3.C Explain how a phylogenetic tree and/or cladogram can be used to infer evolutionary relatedness. 

Science Practices:
2.A Describe characteristics of a biological concept, process, or model represented visually.
