Yes, it's normal to have big ears; ear size and shape vary greatly among individuals.
While "normal" is a broad term, having larger or more protruding ears is not uncommon. The provided reference states that prominent ears affect approximately 1-2% of the population. This means while not the most common trait, it's definitely within the range of typical human variation. Ear size and shape are often hereditary, so you may see it passed down through families.
It's important to remember that what one person considers "big" another might consider perfectly average. Perceptions of what is "normal" are often influenced by societal standards and individual viewpoints. If you have concerns about your ears, consulting a medical professional is always a good idea. They can assess your specific situation and provide personalized advice.
In summary, having larger ears is a normal variation in human anatomy and doesn't necessarily indicate a problem.
