Which of the following is the best direct evidence for recent evolution in a population?
Answer
B. Antibiotic resistance in bacteria
The correct answer is B. Antibiotic resistance in bacteria — Choose the option that fits the definition.
Step-by-step solution
- Identify that recent evolution requires observable change over a short time period.
- Compare options: fossils and DNA similarity show long‑term changes; flower colour is a phenotype.
- Antibiotic resistance in bacteria arises within years and can be traced to specific mutations.
- Choose the option that fits the definition.
Common mistake: Confusing long‑term fossil record with short‑term changes
Concept tested: Recent evolution evidence
