How species are related to one another.

Front

What is the significance of common ancestors in phylogenetic trees?

Back

Common ancestors indicate the evolutionary lineage from which different species have evolved.

Front

What does it mean if two species share a recent common ancestor?

Back

It means they are more closely related to each other than to species that diverged earlier.

Front

What type of data is often used to construct phylogenetic trees?

Back

Front

How can phylogenetic trees be used in understanding biodiversity?

Back

They help scientists understand the evolutionary history and relationships among species, which is crucial for conservation efforts.
