Cladogram practice

Front

What is a cladogram?

Back

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

Front

What does common ancestry mean?

Back

Common ancestry refers to the idea that different species share a common ancestor from which they have evolved over time.

Front

What is the significance of homologous structures?

Back

Homologous structures are physical features in different species that are similar due to shared ancestry, indicating evolutionary relationships.

Front

What are analogous structures?

Back

Analogous structures are features in different species that serve similar functions but do not share a common ancestry, indicating convergent evolution.

Front

What is the purpose of a taxonomic family?

Back

A taxonomic family is a rank in the biological classification system that groups together related organisms that share common characteristics and evolutionary history.

Front

What evidence supports the theory of evolution?

Back

Evidence supporting the theory of evolution includes fossil records, genetic similarities, comparative anatomy, and biogeography.

Front

What is the role of DNA in understanding evolutionary relationships?

Back

DNA analysis helps scientists determine genetic similarities and differences among species, providing insights into their evolutionary relationships and common ancestry.

Front

How do physical features indicate evolutionary relationships?

Back

Physical features, such as bone structure and morphology, can reveal similarities and differences that suggest how closely related different species are.

Front

What is the significance of the split upper lip in Camelidae?

Back

The split upper lip in Camelidae allows for better grazing and feeding adaptations, which is a shared characteristic among members of this family.

Front

What does it mean for species to have evolved to become herbivores?

Back

It means that over time, species have adapted their physical and digestive systems to primarily consume plant material for nutrition.
