Background
History & Context
What Changed
- ▶
BEFORE: Species identification relied almost exclusively on physical morphological traits. NOW: Integrative taxonomy combines physical analysis with DNA barcoding and phylogenetic assessment.
- ▶
BEFORE: Cryptic species (physically identical but genetically distinct) were often incorrectly grouped as a single species. NOW: Genetic data allows precise separation of closely related endemic species.
- ▶
BEFORE: Taxonomy in Indian insect research lagged behind modern global genetic standards. NOW: The ZSI is actively employing molecular biology alongside traditional methods to document biodiversity.
