Phylogenic Trees

Front

What is a phylogenetic tree?

Back

A diagram that represents the evolutionary relationships among various biological species based on similarities and differences in their physical or genetic characteristics.

Front

What is a common ancestor?

Back

An ancestral species from which two or more species have evolved.

Front

What is a cladogram?

Back

A type of phylogenetic tree that shows the relationships among species based on shared characteristics.

Front

What does it mean for species to be closely related?

Back

Species that share a recent common ancestor and have more similar genetic traits.

Front

What is the significance of shared traits in phylogenetic trees?

Back

Shared traits indicate evolutionary relationships and help in understanding how species are related.

Front

What is the purpose of a phylogenetic tree?

Back

To illustrate the evolutionary history and relationships among species.

Front

What are homologous structures?

Back

Anatomical features in different species that share a common ancestry, even if they have different functions.

Front

What are analogous structures?

Back

Features in different species that serve similar functions but do not share a common ancestry.

Front

What is the difference between a phylogenetic tree and a cladogram?

Back

A phylogenetic tree shows the evolutionary relationships and time scale, while a cladogram focuses on the branching patterns without time.

Front

What is the role of genetic data in constructing phylogenetic trees?

Back

Genetic data helps to determine the relationships between species by comparing DNA sequences.
