Who developed the biological species concept?

Ernst Mayr

Explanation

Developed by Ernst Mayr.

What is the primary criterion for defining species in the morphological species concept?

Physical appearance

Explanation

Based on outward characteristics.

Which scientist is known as the father of modern taxonomy?

Linnaeus

Explanation

Considered the pioneer of modern taxonomy.

In taxonomy, what does the term 'binomial nomenclature' refer to?

Naming species using two words

Explanation

Standardized naming convention.

What is a taxon in biological classification?

A category at any level of biological classification

Explanation

A classification category.

Which biological species concept defines a species based on the ability to interbreed and produce fertile offspring?

Biological species concept

Explanation

Based on reproductive compatibility.

Which species concept emphasizes shared evolutionary history and common ancestry?

Phylogenetic species concept

Explanation

Focuses on evolutionary relationships.

In the phylogenetic species concept, how are species defined?

By shared evolutionary history and common ancestry

Explanation

Defined by evolutionary relatedness.

What is the Linnaean system of classification primarily based on?

Physical appearance

Explanation

Based on observable traits.

#10

What is the purpose of a cladogram in phylogenetics?

To represent evolutionary relationships

Explanation

Illustrates evolutionary connections.

#11

Which species concept considers the ecological roles and adaptations of organisms in defining species boundaries?

Ecological species concept

Explanation

Considers ecological niche.

#12

What is the primary focus of the ecological species concept?

Ecological roles and adaptations

Explanation

Focuses on organisms' ecological functions.

#13

Which concept of species classification is most influenced by molecular data and genetic relationships?

Phylogenetic species concept

Explanation

Relies heavily on genetic data.

#14

What is convergent evolution in the context of biological classification?

Evolution of similar traits in unrelated species due to similar environments

Explanation

Unrelated species evolving similar traits.

#15

What is the purpose of a molecular clock in molecular systematics?

To estimate the rate of evolutionary change

Explanation

Estimates evolutionary timelines.
