Select the odd one out w.r.t. proponents of phylogenetic system of classification

Options

A. Hutchinson
B. Engler & Prantl
C. Joseph Dalton Hooker
D. Takhtajan

Answer

To solve the question of identifying the odd one out with respect to proponents of the phylogenetic system of classification, we can follow these steps:

### Step 1: Understand the Concept of Phylogenetic Classification
Phylogenetic classification is based on the evolutionary relationships between organisms, specifically how they are related to their ancestors. This classification system considers the evolutionary history and lineage of the organisms.

**Hint:** Remember that phylogenetic classification focuses on evolutionary relationships.

### Step 2: Analyze Each Option
We have four options to consider:
1. Hutchinson
2. Engler and Prantl
3. Joseph Dalton Hooker
4. Takhtajan

**Hint:** Look at the contributions of each individual to classification systems.

### Step 3: Identify the Proponents of Phylogenetic Classification
- **Hutchinson**: He proposed a system of classification based on phylogeny and published "The Families of Flowering Plants."
- **Engler and Prantl**: They are known for their work in phylogenetic classification and published a significant system in 1886.
- **Takhtajan**: He also contributed to phylogenetic classification, treating flowering plants based on evolutionary relationships.

**Hint:** Focus on whether each individual’s classification system is based on phylogenetic relationships.

### Step 4: Identify the Odd One Out
- **Joseph Dalton Hooker**: His classification system, particularly in conjunction with Bentham, is based on seed plants and does not emphasize phylogenetic relationships. This distinguishes him from the others, who are proponents of phylogenetic classification.

**Hint:** Determine which option does not align with the principles of phylogenetic classification.

### Conclusion
The odd one out with respect to proponents of the phylogenetic system of classification is **Joseph Dalton Hooker**.

**Final Answer:** Joseph Dalton Hooker
