A species-centered knowledge resource
Taxonomy
Search species names and Taxonomy IDs, explore complete lineages and connect each taxon to genomic, sequence and biodiversity data across NGDC.
e.g., "9605" or "Homo sapiens"

Start with a research question
Move from a name or identifier to its lineage, history, relatives and connected datasets without changing tools.
01
Find a taxon and its lineage
Search names and identifiers, then inspect synonyms, ranks, lineages, genetic codes and references.
Open taxonomy search
02
Build the view you need
Browse the complete hierarchy or construct focused trees by depth and Newick-formatted input.
Build a structured tree
03
Resolve change and ancestry
Trace changes to names and Taxonomy IDs, and calculate the lowest common ancestor of multiple taxa.
Review taxonomy history
04
Connect taxonomy to evidence
Follow each taxon into related NGDC and external resources, or download a tailored taxonomic record.
Browse connected records
From taxonomy to discovery
Put classification to work
Integrated workflows extend taxonomic context into sequence comparison, species identification, disease tracing, structural biology and conservation.
Alignment & phylogeny
Compare sequences and derive evolutionary relationships.
DNA barcode identification
Place a query sequence in evolutionary context.
Viral epidemiology
Explore strain relationships across time and space.
Protein evolution
View structures alongside phylogenetic context.
Biodiversity conservation
Connect the tree of life with geospatial evidence.
