Bio176/276 - The Developmental Basis of Animal Body Plan Evolution

Animals are grouped into phyla with defined organizational characteristics such as multicellularity, axis organization, and nervous system organization, as well as morphological novelties such as eyes, limbs and segments.

This course explores the developmental and molecular origins of there animal innovations.

Offered alternate years.

Prerequisites: None.

BIOHOPK 160H - Developmental Biology in the Ocean

Lab course is designed to introduce students to the diversity in the early developmental strategies of marine invertebrates and how an understanding of these microscopic life histories is key to understanding the evolutionary diversification of phyla and the distribution of their more familiar adults.

Emphasis is on hands-on collection, spawning, observation and manipulation of embryos and their larvae.

BIOS 236: Developmental Biology in the Ocean - Comparative Embryology and Larval Development

This is a three-week course at Hopkins Marine Station. Focuses on the embryology and larval development of a broad range of marine invertebrate phyla. The goal of the course is to give students an appreciation of the range of developmental strategies and larval forms in the ocean and why this is critical for constructing hypotheses of EvoDevo and animal evolution. Includes observation and documentation of the development of embryos and larvae by scientific illustration and photo/video microscopy.
