Select an incorrect statement :

Options

A. Populations evolve to maximise their reproductive fitness , also called Darwinian fitness
B. Under a particular set of selection pressures , organisms evolve towards the most efficient reproductive strategy
C. Some organisms breed many times in their lifetime e.g. Pacific salmon fish
D. Some organisms produce a large number of small - sized offspring (Oysters , pelagic fishes) while others produces a small number of large - sized offspring (birds , mammals)

Answer

To solve the question "Select an incorrect statement," we will analyze each option provided in the video transcript step by step.

### Step 1: Analyze the First Statement
**Statement:** "Populations which evolve to maximize their reproductive fitness are also called Darwinian fitness."

**Analysis:** This statement is correct. Darwinian fitness refers to the ability of an organism to pass on its genes to the next generation, which is often associated with maximizing reproductive success.

### Step 2: Analyze the Second Statement
**Statement:** "Under a particular set of selection pressures, organisms evolve towards the most efficient reproductive strategy."

**Analysis:** This statement is also correct. Organisms adapt to their environment and selection pressures, which include resource availability and environmental conditions, to enhance their reproductive strategies.

### Step 3: Analyze the Third Statement
**Statement:** "Some organisms breed many times in their lifetime. For example, Pacific Salmon Fish."

**Analysis:** This statement is incorrect. Pacific Salmon are known for being semelparous, meaning they breed only once in their lifetime and then die. Therefore, this statement misrepresents the breeding behavior of Pacific Salmon.

### Step 4: Analyze the Fourth Statement
**Statement:** "Some organisms produce a large number of small-sized offspring like oysters and pelagic fish."

**Analysis:** This statement is correct. Many aquatic organisms, such as oysters and pelagic fish, produce a large number of small offspring as a reproductive strategy to ensure that some survive to adulthood.

### Conclusion
After analyzing all the statements, the incorrect statement is the third one regarding Pacific Salmon.

**Final Answer:** The incorrect statement is Option 3.
