âEar comes from the ancient word âahs, which meant â husk of corn.. In English, sometimes the ear also is referred to as a â cob  or a âpole.. The ear is the spiked part of the corn plant that contains kernels, the delicious yellow tidbits we love to nibble on in the summertime.
It is a human invention, a plant that does not exist naturally in the wild. It can only survive if planted and protected by humans. Scientists believe people living in central Mexico developed corn at least 7000 years ago. It was started from a wild grass called teosinte. Teosinte looked very different from our corn today. The kernels were small and were not placed close together like kernels on the husked ear of modern corn.
