Phylogeny and Phylogenetics Quiz

What is the main focus of phylogenetics?

• Examining the behavior of different species

• Classifying organisms based on their habitats

• Analyzing the evolutionary relationships between organisms

• Studying the physical features of organisms

Which type of data is used to determine evolutionary relationships?

• DNA and protein sequences

• Behavioral patterns

• Dietary habits

• Geographical distribution

What does a phylogenetic tree represent?

• The dietary habits of species

• The geographical distribution of species

• The evolutionary relationships between species

• The physical characteristics of species

In a phylogenetic tree, what does a node represent?

• A species' behavior

• A species' diet

• A common ancestor of the descendants

• A species' habitat

What are sister groups in a phylogenetic tree?

• Species that exhibit similar behaviors

• Descendants from the same node

• Species that have the same diet

• Species that share the same habitat

Which species is more closely related to the Golden Hamster?

• Deer Mouse

• Brown Rat

• House Mouse

• Chinese Hamster

How can phylogeny confirm the classification of an organism?

• By examining its physical appearance

• By analyzing its diet

• By observing its behavior

• By studying its evolutionary relationships

Why is phylogeny not based on grouping organisms into taxa?

• Because some organisms do not fit neatly into a given group

• Because it focuses on physical features

• Because it uses behavioral data

• Because it relies on geographical distribution

What is a limitation of taxonomic classification?

• It focuses on geographical distribution

• It is based on DNA sequences

• It groups organisms by their diet

• It does not consider evolutionary relationships

How does phylogeny overcome the problems of taxonomic classification?

• By analyzing geographical distribution

• By not grouping organisms into taxa

• By focusing on physical features

• By grouping organisms based on their diet
