Step 1: Begin by understanding the concept of natural selection. Natural selection is a mechanism of evolution where individuals with traits that provide a survival or reproductive advantage are more likely to pass those traits to the next generation.
Step 2: Evaluate the first statement: 'Natural selection leads to the immediate formation of new species in a single generation.' This is incorrect because speciation is a gradual process that occurs over many generations, not immediately.
Step 3: Evaluate the second statement: 'Traits acquired during an organism's lifetime are passed directly to offspring.' This is incorrect because acquired traits (e.g., learned behaviors or physical changes due to environment) are not inherited genetically. Only traits encoded in an organism's DNA can be passed to offspring.
Step 4: Evaluate the third statement: 'Individuals with advantageous traits are more likely to survive and reproduce.' This is correct because natural selection favors individuals with traits that enhance survival and reproduction, leading to a higher likelihood of passing those traits to offspring.
Step 5: Evaluate the fourth statement: 'All individuals in a population have an equal chance of surviving and reproducing.' This is incorrect because natural selection is based on differential survival and reproduction, meaning individuals with advantageous traits have a higher chance compared to others.
