A species is a group of living organisms that are similar to each other in specific characteristics and can interbreed to produce fertile offspring. The concept of a species is one of the fundamental units of biological classification and plays a key role in the study of biodiversity.
There are various definitions of species, but the most widely accepted is the biological species concept, which defines a species as a group of populations reproductively isolated from other groups, meaning that members of different species cannot interbreed to produce viable offspring. This definition is based on the idea that species are evolving units, and that the ability to interbreed is an indicator of evolutionary relatedness.
It’s important to note that the concept of a species is not a fixed or absolute entity, but rather a useful tool for understanding the diversity of life on Earth. Some species may evolve into new species over time, while others may merge into a single species through hybridization. Additionally, new species can also arise through processes such as speciation by geographical isolation.

Frequently Asked Questions (FAQs) on Species
What is a simple definition of species?
A species is a group of living organisms that share similar characteristics and are capable of interbreeding to produce offspring that are also able to reproduce. Simply put, a species is a defined category of plants or animals that are biologically distinct from other types.
What are species and an example?
A species is a group of living organisms that are similar to each other in certain characteristics and can interbreed to produce fertile offspring. An example of a species is the domestic dog, which is scientifically known as Canis lupus familiaris. Domestic dogs belong to the species Canis lupus and are considered a separate species from their closest wild relative, the gray wolf (Canis lupus). Another example is the common chimpanzee (Pan troglodytes), which is a species of primate found in central and west Africa.
What is species in zoology?
In zoology, a species is a classification level used to group similar organisms based on their biological and morphological characteristics. Zoologists use the concept of species as a way to understand the diversity of life on Earth and to study the relationships between different organisms. A species is considered to be a group of individuals that are similar in appearance, behavior, and genetics, and that are capable of interbreeding and producing viable offspring.
The concept of species in zoology is not always clear-cut, as there are many different definitions and criteria used to determine whether organisms belong to the same species. For example, some species may be determined based on morphological similarities, while others may be defined based on genetic or behavioral characteristics. Additionally, there are some species that are difficult to classify, as they may exhibit characteristics that overlap with multiple species, or they may have evolved in a way that makes it difficult to determine their evolutionary relationships. Nevertheless, the concept of species remains an important tool for understanding the diversity of life on Earth and for conserving the world’s biodiversity.
What is species in biology example?
In biology, species is a classification level used to group similar organisms based on their biological and morphological characteristics. A species is considered to be a group of individuals that are similar in appearance, behavior, and genetics, and that are capable of interbreeding and producing viable offspring.
An example of a species in biology is Homo sapiens, the scientific name for human beings. Humans belong to the genus Homo and are the only surviving species of this genus. Another example is the common house cat, which is scientifically known as Felis catus. The domestic cat is a separate species from its wild ancestor, the African wildcat (Felis silvestris lybica). These two species are similar in appearance but are distinct from each other because they cannot interbreed to produce fertile offspring.
It’s important to note that the concept of species is not always clear-cut, and different criteria and definitions may be used to determine whether organisms belong to the same species. Nevertheless, the concept of species remains a useful tool for understanding the diversity of life on Earth and for conserving the world’s biodiversity.
What is a species concept in biology?
The species concept in biology is a way to define and categorize groups of similar organisms. The species concept plays a crucial role in the study of biodiversity and is a fundamental unit of biological classification. There is no single, universally accepted definition of species, and different species concepts have been proposed over the years. Some of the most commonly used species concepts include:
- Biological species concept: This is the most widely accepted species concept and defines a species as a group of populations reproductively isolated from other groups, meaning that members of different species cannot interbreed to produce viable offspring.
- Morphological species concept: This species concept is based on physical appearance, and defines a species as a group of organisms that have similar morphological or structural characteristics.
- Phylogenetic species concept: This species concept is based on evolutionary relationships, and defines a species as a group of organisms that share a common ancestry and are distinct from other evolutionary lineages.
- Ecological species concept: This species concept is based on the niche or role that an organism plays in its ecosystem, and defines a species as a group of organisms that occupy a unique and complementary role in the ecosystem.
It’s important to note that different species concepts may give different results, and the choice of species concept depends on the questions being asked and the goals of the study. Nevertheless, the species concept remains a useful tool for understanding the diversity of life on Earth and for conserving the world’s biodiversity.
What is species concept class 11?
In Class 11 biology, the species concept is a way to define and categorize groups of similar organisms. The species concept plays a crucial role in understanding the diversity of life on Earth and is a fundamental unit of biological classification. There are different species concepts that have been proposed over the years, but the most commonly discussed species concept in Class 11 biology is the Biological Species Concept.
The Biological Species Concept defines a species as a group of populations reproductively isolated from other groups, meaning that members of different species cannot interbreed to produce viable offspring. This means that the members of a species can breed among themselves and produce offspring that are also capable of reproducing, but they cannot breed with members of other species and produce viable offspring.
In Class 11 biology, students learn about the concept of species and its importance in understanding the diversity of life on Earth. They also learn about the different species concepts and how they can be used to define and categorize different groups of organisms. Understanding the species concept is an important foundation for further studies in biology and is useful in fields such as ecology, evolution, and conservation biology.
What are genus and species Class 11?
In Class 11 biology, genus and species are two levels of classification used to categorize and organize the diversity of life on Earth. The classification system used in biology is called taxonomy, and it is based on a hierarchy of classification levels, starting with the largest group (kingdom) and ending with the smallest group (species).
The genus is a taxonomic category that sits between the family and species levels. It is a group of closely related species that have similar morphological, behavioral, and genetic characteristics. For example, the genus Homo includes the species Homo sapiens (humans), Homo neanderthalensis (Neanderthals), and Homo erectus (erectus humans).
Species, on the other hand, is the smallest and most specific level of classification in biology. It is a group of organisms that are similar in appearance, behavior, and genetics and that are capable of interbreeding and producing viable offspring. The species name is written in a specific format, with the genus name followed by the species name, and is known as the binomial name. For example, the binomial name for humans is Homo sapiens.
In Class 11 biology, students learn about the classification system used in biology and the importance of genus and species in understanding the diversity of life on Earth. They also learn about the different levels of classification, including kingdom, phylum, class, order, family, genus, and species, and how organisms can be organized and grouped based on their morphological, behavioral, and genetic characteristics.
