7A Evidence practice short version

Front

What is a dendrogram?

Back

A dendrogram is a diagram that shows the arrangement of the clusters produced by hierarchical clustering, often used to represent evolutionary relationships among organisms based on molecular data.

Front

What does it mean for organisms to be genetically similar?

Back

Genetically similar organisms share a higher percentage of their DNA sequences, indicating a closer evolutionary relationship.

Front

What is a common ancestor?

Back

A common ancestor is an ancestral species from which two or more species have evolved.

Front

How can DNA and RNA sequences be used in classification?

Back

DNA and RNA sequences can be analyzed to determine genetic similarities and differences, which helps classify organisms based on their evolutionary relationships.

Front

What is the significance of geographical distribution in evolution?

Back

Geographical distribution can provide insights into how species evolved and adapted to different environments, often indicating their ancestral origins.

Front

What is the role of protein comparison in determining relatedness?

Back

Comparing proteins, such as cytochrome b, among different populations can reveal genetic differences and similarities, helping to establish evolutionary relationships.

Front

What is the taxonomic family Camelidae?

Back

Camelidae is a family of animals that includes camels, llamas, and alpacas, characterized by specific physical features such as two toes and a split upper lip.

Front

What evidence supports the idea of a common ancestor among species?

Back

Similar physical features, genetic sequences, and evolutionary traits among species provide evidence that they share a common ancestor.

Front

What is the importance of amino acid sequence comparison?

Back

Comparing amino acid sequences helps scientists determine the evolutionary relationships among different organisms based on their genetic makeup.

Front

What does it mean for species to evolve?

Back

Evolution refers to the process by which species change over time through genetic variation and natural selection.
