Availability information for this program

The Biology of... series of core curriculum programs explores the "deep branches" on the tree of life to reveal a modern view of the classification and phylogeny of each group studied in the biology curricula. The narrated programs feature new techniques of microscopy, animation, and photography to reveal the structure, process, and behavior in living things.

Episodes:

  • Arthropods

    Describes the phylum characteristics and major groups of arthropods: crustaceans; chelicerates (scorpions, spiders, ticks and mites); and the uniramians (centipedes, millipedes and insects). The focus is on adaptations, life cycles, and evolutionary relationships.

  • Chordates

    The unique features of this group -- a supporting rod (notochord), hollow dorsal nerve chord, pharyngeal gills, and a tail that extends behind the anus -- are found in three evolutionary lines; urochordates (tunicates); cephalochordates (lancelets); and vertebrates. This program emphasizes the key adaptations that led to the diversification of chordates, their emergence on land, and the proliferation of the modern vertebrate groups.

  • Protists

    The term 'protists' covers a wide range of microscopic organisms formerly clumped into 'Kingdom Protista'. New molecular analyses show that the protistan lines of evolution go so far back in time they represent different kingdoms of life. Through stunning photography of living protists, we are introduced to amoebas, flagellates, algae, and the elegant ciliated protists.

  • The Light Microscope: Window on a Microcosm

    Demostrates techniques for using an average microscope to achieve spectacular images. Emphasis is on correct lighting procedures and the techniques required for viewing living cells.
