Meaning and Definition
A biological classification system that groups organisms based on common ancestry, emphasizing evolutionary relationships rather than just physical similarities.
A method of hypothesizing relationships among organisms based on the principle of shared derived characteristics. More broadly, it can refer to any hierarchical classification based on branching patterns of descent.

Frequently Asked Questions
They are closely related and often used interchangeably, but phylogenetics is broader, encompassing the study of evolutionary history, while cladistics is specifically a method for inferring phylogenetic relationships.
Yes, the conceptual framework has been borrowed by disciplines like historical linguistics (where it's called 'cladistics' or 'phylogenetic linguistics') and archaeology to model the descent and branching of language families or cultural traits.
A clade is a group of organisms that includes a common ancestor and all of its descendants. It is the fundamental unit in cladistic classification.
It aims to be objective by relying on testable hypotheses about shared evolutionary innovations (synapomorphies) and using computer algorithms to find the tree that requires the fewest evolutionary changes (parsimony), reducing reliance on subjective judgement of 'importance' of traits.
A biological classification system that groups organisms based on common ancestry, emphasizing evolutionary relationships rather than just physical similarities.
Cladistics is usually formal, academic, technical in register.
