Who thinks like Darwin?

Explanation

To determine who thinks like Darwin between Karthik and Sukesh, we need to analyze their beliefs about the long necks of giraffes.

1. **Understanding Karthik's Belief**: Karthik believes that giraffes have long necks because they have stretched their necks. This idea suggests that giraffes developed long necks through their own efforts during their lifetime, which is a concept associated with Lamarckism. Lamarck proposed that characteristics acquired during an organism's lifetime could be passed on to the next generation.

2. **Understanding Sukesh's Belief**: Sukesh believes that giraffes have long necks because the ones with long necks were inherited. This belief aligns with Darwin's theory of evolution, which emphasizes natural selection and the inheritance of traits. According to Darwin, traits that provide an advantage for survival and reproduction are more likely to be passed on to future generations.

3. **Conclusion**: Since Sukesh's belief aligns with Darwin's theory of evolution, he thinks like Darwin. In contrast, Karthik's belief aligns with Lamarck's theory, which does not reflect Darwin's views on inheritance and evolution.
