Lancelet
Branchiostoma lanceolatum
A primitive chordate that provides insights into vertebrate evolution and development.
Dataset Statistics
Overview
Lancelet (Branchiostoma lanceolatum) is a crucial invertebrate chordate model organism that provides unique insights into the evolutionary origins of vertebrates. As the closest living invertebrate relative to vertebrates, lancelet serves as an essential bridge for understanding the transition from invertebrates to vertebrates and the evolution of fundamental vertebrate characteristics. This portal provides genomic resources for comparative studies of gene regulation, development, and the molecular basis of chordate evolution.
Research Areas Covered
- Evolutionary Biology: Vertebrate origins, chordate evolution, phylogenetic studies
