PHYLOGENETIC TREES

Front

What is the correct representation of the binomial scientific name for the African lion?

Back

Panthera leo (all in italics)

Front

Based on a phylogenetic tree, how can you determine genetic similarity between species?

Back

By comparing the branching patterns; species that share a more recent common ancestor are more genetically similar.

Front

What unique trait do only humans possess according to cladograms?

Back

Opposable thumbs.

Front

What does the term 'clade' refer to in phylogenetics?

Back

A clade is a group of organisms that includes an ancestor and all its descendants, and is considered monophyletic.

Front

What is the definition of a monophyletic group?

Back

A monophyletic group is a group of organisms that consists of a common ancestor and all its descendants.

Front

How can you identify structural homology between organisms?

Back

By comparing anatomical structures that are similar due to shared ancestry.

Front

What is the significance of phylogenetic trees in biology?

Back

Phylogenetic trees illustrate the evolutionary relationships among various biological species based on similarities and differences in their physical or genetic characteristics.

Front

What is the difference between homology and analogy in evolutionary biology?

Back

Homology refers to traits inherited from a common ancestor, while analogy refers to traits that arise independently due to convergent evolution.

Front

What does it mean for organisms to belong to the same class but different orders?

Back

It means they share a higher taxonomic rank (class) but have diverged into different evolutionary paths (orders).

Front

Which organisms would show the greatest degree of structural homology: organisms from the same class or the same order?

Back

Organisms from the same order (D and F) would show the greatest degree of structural homology.
