Biological concept of species was given by _____ and it is based on _____

Options

A. Lamarck, physiological isolation
B. Linnaeus, morphological isolation
C. Ernst Mayr, mechanical isolation
D. Ernt Mayr, reproduction isolation

Answer

**Step-by-Step Solution:**

1. **Identify the Scientist**: The biological concept of species was proposed by Ernst Mayr. He is recognized for his contributions to the understanding of species in the context of biological classification.

2. **Understand the Basis of the Concept**: The biological concept of species is based on the idea of reproductive isolation. This means that members of the same species are capable of interbreeding and producing fertile offspring, while individuals from different species are typically unable to do so.

3. **Explain Reproductive Isolation**: Reproductive isolation can occur through various mechanisms, ensuring that species remain distinct. For example, if two different species (like a horse and a donkey) mate, they may produce a mule, which is typically sterile. This illustrates that while they can mate, they do not belong to the same species as they cannot produce fertile offspring.

4. **Clarify Misconceptions**: It’s important to note that while Linnaeus is known as the father of taxonomy for his work on binomial nomenclature, he did not propose the biological concept of species. Instead, that credit goes to Ernst Mayr.

**Final Answer**: The biological concept of species was given by Ernst Mayr, and it is based on reproductive isolation.
