Thus, according to the biological species concept, you could consider them one species. They come into contact with each other in nature and they do interbreed. Lions and tigers can reproduce in captivity and some of their offspring are even fertile themselves.

What is meant by biological concept?
The biological species concept is the most widely accepted species concept. It defines species in terms of interbreeding. For instance, Ernst Mayr defined a species as follows: “species are groups of interbreeding natural populations that are reproductively isolated from other such groups.”
What are the main biological concepts?
- Order. Organisms are highly organized structures that consist of one or more cells.
- Sensitivity or Response to Stimuli. Organisms respond to diverse stimuli.
- Reproduction.
- Adaptation.
- Growth and Development.
- Regulation.
- Homeostasis.
- Energy Processing.
What are three biological concepts?
- Cell Theory: all living organisms are composed of cells.
- Gene Theory: traits are inherited through gene transmission.
- Evolution: any genetic change in a population that is inherited over several generations.
What are the 4 types of species concepts?
- Typological Species Concept.
- Nominalistic Species Concept.
- Biological Species Concept.
- Evolutionary Species Concept.
- Taxonomic Species.
- Microspecies.
- Biological Species.
- Evolutionary Species.
What is the biological concept of health?
This generally accepted definition states that “health is a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity” (11).
What are the 6 biological principles?
Six biology principles: Organization and function, adaptation, response to the environment, growth and development, reproduction, and Homeostasis. 3. What are the four principles of biology? The four principles of biology are cell theory, evolutionary theory, gene theory, and concept of homeostasis.
What are the 7 major themes of biology?

- evolution.
Who gave biological concept of species?
The development of what became known as the biological species concept began with a paper by Theodosius Dobzhansky in 1935, and was amplified by a mutualistic interaction between Dobzhansky, Alfred Emerson and Ernst Mayr after the second world war.
How many species concepts are there?
The species problem is the set of questions that arises when biologists attempt to define what a species is. Such a definition is called a species concept; there are at least 26 recognized species concepts.
Why biological species concept is best?
The biological species concept (BSC) was designed to aid understanding of biological diversity, particularly the ubiquitous observation that sexually reproducing organisms exist in more or less distinct phenotypic and genetic clusters rather than in a continuum of forms.
What is the best species concept?
By far the most well-known species concept is the biological species concept, which was proposed by evolutionary biologist Ernst Mayr. The biological species concept states that a species is a group of actually or potentially interbreeding natural populations which are reproductively isolated from other such groups.
What are the advantages of biological species concept?
Advantages: Recognizes the role of history in generating species explicitly and can be reasonably objective. Can use nearly any sort(s) of data. (The subdivision of lineages into species can be rather arbitrary and subspecies are not recognized.
What are the 4 concepts of health?
Four distinct conceptions of health emerged from responses to the “how do you know” question: physical, psychosocial, capacity, and control. While prevalence varied with survey year as well as respondent age and education, these four concepts were evident in both 1995 and 2002.
What are the 8 concepts of health?
The eight dimensions include: emotional, spiritual, intellectual, physical, environmental, financial, occupational, and social. Wellness can be compromised by lack of support, trauma, unhelpful thinking styles, chronic illness/disability, and substance use.
What is a biological and how is it used?
In medicine, refers to a substance made from a living organism or its products. Biologicals may be used to prevent, diagnose, treat or relieve of symptoms of a disease. For example, antibodies, interleukins, and vaccines are biologicals. Biological also refers to parents and children who are related by blood.
What are the 8 principles of life biology?
Those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution.
What are the 7 characteristics of life?
Big Ideas: All living things have certain traits in common: Cellular organization, the ability to reproduce, growth & development, energy use, homeostasis, response to their environment, and the ability to adapt.
How many biological principles are there?
Four unifying principles form the foundation of modern biology: cell theory, evolutionary theory, the gene theory and the principle of homeostasis. These four principles are important to each and every field of biology.
What are the 5 basic principles of biology?
Reproduction, homeostasis, evolution, metabolism, heredity.
What are the 10 themes of biology?
- Emergent Properties. Life exists in a hierarchical form, from single-celled bacteria to the entire biosphere, with all its ecosystems.
- The Cell.
- Heritable Information.
- Structure and Function.
- Environmental Interactions.
- Feedback and Regulation.
- Unity and Diversity.
- Evolution.
What is the unifying concept of biology?
The theory of evolution is quite rightly called the greatest unifying theory in biology.
Where is biological concept of species is mainly based on?
Complete answer: Mayr’s biological concept of species is mainly based on reproductive isolation. A species is defined as a group of closely related organisms which are capable of inbreeding to produce fertile offspring.
What can the biological species concept not be applied to?
The biological species concept cannot be applied, if organisms reproduce only asexually, if sexual reproduction is not known or if mating experiments are not possible. In such cases an alternative species concept has to be chosen. Usually the morphospecies concept has been the fallback option.
Which of the following best describes the concept of biological species?
Summary. The biological species concept defines a species as a group of individuals living in one or more populations that can potentially interbreed to produce healthy, fertile offspring. Other species concepts exist and may be more useful for certain types of organisms.
