Who was the first to draw attention to the fact that bees communicate by means of definite movements and now called as "bee dances"?

Options

A. T.A. Huxley
B. Andreas Vesalius
C. A.I. Oparin
D. Ernest Spytzner

Answer

To answer the question regarding who was the first to draw attention to the fact that bees communicate through definite movements known as "bee dances," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the individual who first recognized that bees communicate through specific movements, which are now referred to as "bee dances."

2. **Identifying Key Terms**: The key terms in the question are "bees," "communicate," "definite movements," and "bee dances." This indicates that we are looking for a person associated with the study of bee behavior.

3. **Recalling Relevant Information**: From the study of entomology and animal behavior, we know that certain researchers have made significant contributions to our understanding of how bees communicate.

4. **Recognizing the Correct Individual**: The video transcript identifies Ernest Spytner as the correct answer. He was the first to draw attention to the communication methods of bees through their movements.

5. **Understanding Bee Dances**: The transcript explains that there are two types of bee dances:
- **Round Dance**: Performed when the food source is within 50 to 75 meters from the hive.
- **Waggle Dance**: Performed when the food source is farther than 50 meters from the hive.

6. **Eliminating Other Options**: The other individuals mentioned (T. A. Huxley, Andreas Vesalius, and Oparin) are known for different contributions in biology and do not relate to the study of bee communication.

7. **Final Conclusion**: Therefore, the answer to the question is that Ernest Spytner was the first to draw attention to bee dances.

### Final Answer:
**Ernest Spytner**
