Many people wonder why humans have hair on their heads.

(Banyak orang bertanya-tanya mengapa manusia memiliki rambut di kepala mereka.)

While our ancestors, people who lived before us, lost body fur, and hair on the head seems to be really practical. It keeps the brain safe because it is insulation in cold, on the other hand, it stops the brain from overheating when it is too hot. Also, hair absorbs sweat and protects the skin from UV rays. Scientists believe that in the past, hair played an important role in choosing a sexual partner. But these days, hats protect our heads, so hair doesn’t seem as important anymore.

(Saat nenek moyang kita, orang-orang yang hidup sebelum kita, kehilangan bulu tubuh, dan rambut di kepala tampaknya sangat praktis. Rambut menjaga otak tetap aman karena menjadi insulasi dalam cuaca dingin, di sisi lain, rambut juga mencegah otak menjadi terlalu panas saat cuaca terlalu panas. Selain itu, rambut juga menyerap keringat dan melindungi kulit dari sinar UV. Para ilmuwan percaya bahwa di masa lalu, rambut berperan penting memilih pasangan seksual. Tetapi saat ini, topi melindungi kepala kita, jadi rambut tidak lagi penting.)

Kata-kata sulit: fur (bulu), insulation (insulasi), sweat (keringat).
