Front

What is the significance of shared characteristics in cladistics?

Back

They help determine the evolutionary relationships and lineage of organisms.

Front

What role does natural selection play in evolution?

Back

It drives the adaptation of species to their environment, leading to evolutionary change.

Front

What are the main components of a cladogram?

Back

Nodes (representing common ancestors) and branches (representing the evolutionary paths of species).

Front

How do scientists use cladograms in biology?

Back
