Species Identification Techniques
Methods and tools used to identify organisms to species level in field or laboratory settings.
Real World
The Barcode of Life project used DNA barcoding to discover that many 'swordfish' steaks sold in US restaurants were actually cheaper escolar — demonstrating molecular ID's power beyond traditional morphology.
Exam Focus
Distinguish clearly between dichotomous keys (morphology-based, field use) and DNA barcoding (lab-based, higher accuracy) when 'comparing' identification techniques.
