Verified step by step guidance
1
Step 1: Begin by understanding the concept of growth spurts. Growth spurts are defined as periods of rapid physical growth, often associated with significant changes in height, weight, and overall body development.
Step 2: Analyze the statement 'Growth spurts only occur in humans and not in other animals.' This statement implies that growth spurts are exclusive to humans, which contradicts biological evidence showing that many animals experience growth spurts during specific life stages.
Step 3: Review the role of hormonal changes in growth spurts. Hormones such as growth hormone, thyroid hormone, and sex hormones (e.g., estrogen and testosterone) are critical in regulating and triggering growth spurts, especially during puberty.
Step 4: Examine the statement 'Growth spurts typically occur during puberty.' This is accurate, as puberty is a well-documented period of rapid physical growth and development in humans.
Step 5: Conclude that the statement 'Growth spurts only occur in humans and not in other animals' is NOT true, as growth spurts are observed in various animal species during their developmental stages.
