Front

What is the definition of classification in biology?

Back

Organizing things into groups according to shared characteristics.

Front

What is a phylogenetic tree?

Back

Front

What is the primary purpose of a cladogram?

Back

To illustrate the evolutionary relationships and common ancestry among species.

Front

What are homologous structures?

Back

Anatomical features in different species that share a common ancestry.

Front

What is the difference between homologous and analogous structures?

Back

Homologous structures arise from a common ancestor, while analogous structures arise from convergent evolution and serve similar functions but do not share a common ancestry.

Front

What is the significance of genetic variation in a population?

Back

It increases the chances of survival and adaptation to changing environments.
