Organisms present at different places without any traces in between show

Options

A. Speciation
B. Discontinuous distribution
C. Punctured equilibrium
D. Migration

Answer

To solve the question "Organisms present at different places without any traces in between show," we need to analyze the options provided and understand the concepts related to the distribution of organisms. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Question
The question is asking about organisms that are found in different geographical locations without any intermediate forms or connections between them. This suggests a specific type of distribution.

**Hint:** Think about how organisms can be distributed across different areas and what that implies about their evolutionary relationships.

### Step 2: Analyze the Options
1. **Speciation**: This refers to the process by which new species arise from existing ones. While speciation can lead to organisms being found in different places, it does not specifically address the absence of traces in between.

**Hint:** Consider whether speciation implies a direct connection or continuity between the organisms.

2. **Punctuated Equilibrium**: This is a theory in evolutionary biology that suggests species remain relatively stable for long periods, punctuated by brief periods of rapid change. This concept does not directly relate to the distribution of organisms across different areas without traces.

**Hint:** Reflect on whether this theory relates to geographical distribution or the evolutionary process itself.

3. **Migration**: This involves the movement of organisms from one place to another. While migration can lead to organisms being found in different locations, it does not explain the lack of traces in between those locations.

**Hint:** Think about whether migration implies a permanent presence in different locations or just temporary movement.

4. **Discontinuous Distribution**: This term refers to organisms being found in separate locations without any intermediate forms connecting them. This is the most appropriate answer to the question.

**Hint:** Consider what "discontinuous" means in terms of geographical and evolutionary relationships.

### Step 3: Identify the Correct Answer
Based on the analysis, the correct answer is **Discontinuous Distribution**. This concept accurately describes the situation where organisms are present in different places without any traces in between.

**Final Answer:** The organisms present at different places without any traces in between show **Discontinuous Distribution**.
