The human brain is a marvel of engineering. When you were in your mother’s womb, your brain was built according to a preset plan, and thousands of new brain cells were constructed every minute! Researchers estimate that an adult’s brain contains close to 100 billion special cells called neurons​—assembled into a package that weighs about 3.3 pounds (1.5 kg). One of the brain’s amazing abilities concerns speech. With each word you say, your brain has to coordinate the movement of some 100 muscles in your tongue, throat, lips, jaw, and chest. All those muscles have to move according to precise timing if the words are to be understood. A study published in 2019 showed that newborn babies can pick out individual words. This finding reinforces what many researchers believe​—that we are born with the ability to recognize and learn languages. Certainly, our ability to speak is a gift from God. w20.05 22-23 ¶8-9
