In case of evolution, which of the following statements is not correct ?

Options

A. Fossilized animals provide important information to trace evolution .
B. Wing of birds and forelimbs of cows are homologous.
C. In higher animals , early development stages are similar.
D. Variation among individuals are not important in natural selection .

Answer

To determine which statement regarding evolution is not correct, we will analyze each provided statement step by step.

### Step 1: Understand Evolution
Evolution is the gradual process of change and development in living organisms over a long period of time. It involves the transformation of species from simpler forms to more advanced forms.

### Step 2: Analyze Each Statement
1. **Fossilized animals provide important information to trace evolution.**
- This statement is **correct**. Fossils are crucial in understanding the evolutionary history of organisms as they provide evidence of past life forms and their changes over time.

2. **Wings of birds and forelimbs of cows are homologous.**
- This statement is also **correct**. Homologous structures are those that have a similar origin but may serve different functions. The wings of birds and the forelimbs of cows share a common ancestral origin, making them homologous.

3. **In higher animals, early development stages are similar.**
- This statement is **correct**. Many higher animals (vertebrates) exhibit similar embryonic stages, which reflects their common ancestry before diverging into different species.

4. **Variations among individuals are not important in natural selection.**
- This statement is **not correct**. Variations among individuals are crucial for natural selection. They provide the raw material for evolution, as natural selection acts on these variations to favor traits that enhance survival and reproduction.

### Conclusion
The statement that is not correct is: **"Variations among individuals are not important in natural selection."**
