“There is grandeur in this view of life … from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.” Charles Darwin, Origin of Species, 1859

“... to the degree that we come to understand other organisms, we will place a greater value on them, and on ourselves.” Edward O. Wilson, Biophilia, 1984

Course Description
An introduction to the diversity of organisms, including their sampling, identification, classification, evolution and conservation. Diversity will be explored from the organismal to the biome level and will incorporate hands-on investigations in laboratory and field settings.

 

Course Goals

  • Enhance awareness of and appreciation for biological diversity, both locally and globally
  • Acquire “face-name” recognition of the major groups (phyla) of life
  • Appreciate the interplay between organism and environment (biotic and abiotic) and how this interplay influences biological diversity on micro- and macroevolutionary scales
  • Gain exposure to and proficiency in practices related to the study of biological diversity, such as:
    • sampling, identification and classification of organisms
    • analysis and interpretation of biological data (e.g. phylogenies, diversity indices)
    • effective communication of ideas and scientific findings

By the end of this course, students will be able to discuss the following in an informed manner:

The scope of biodiversity How many species are there? How do we know? What is the importance of biological diversity? How is biodiversity distributed on earth, regionally and globally? What factors threaten biodiversity?

The origin and diversification of life When did life first appear? What were the earliest life forms like? What major innovations led to novel forms of life? What are the major branches on the tree of life? What factors promote macro- and microevolutionary changes in life forms? Has diversity within groups changed over time (is it increasing, decreasing, or not changing?)

Phylogenetics and systematics How is the diversity of life named and classified? What are the evolutionary relationships between different forms of life? How are these relationships determined? How has our view of the tree-of-life changed over time? What key characteristics do we use to identify and classify various organisms?

Community diversity, ecosystems and biomes What roles do organisms play in maintaining community diversity and ecosystem stability? What is known about the biological diversity within various biomes?

Biodiversity and conservation What are the major threats to biodiversity? How does the human population impact biological diversity? Is the biodiversity crisis real? What are some strategies for conserving and restoring biodiversity?

Biodiversity and human nature Do humans have an innate affinity to associate with other life forms? If so, does this mean we possess a conservation ethic? To what extent are humans dependent on other organisms to sustain humanity?
