MADISON: Ketika manusia moden begitu bangga dengan kecerdasannya, penemuan terbaru menunjukkan saiz otak manusia hidup 20,000 tahun lalu lebih besar, iaitu hampir sebesar bola tenis.

"Dalam 20,000 tahun terakhir, isi padu otak manusia menyusut daripada 1.500 sentimeter padu menjadi sekitar 1.350 sentimeter padu. Terjadi kepada lelaki mahupun wanita, tidak mengira kumpulan etnik," kata Pakar Antropologi dari University of Wisconsin, Kathleen McAuliffe, dalam akhbar Britain Daily Mail, semalam.

Pelbagai spekulasi dikembangkan pakar bagi menjelaskan penemuan mengejutkan itu. Antaranya dikaitkan dengan cara hidup masa purba termasuk tempoh zaman batu tua (Upper Paleolithic).

Ketika itu, kegiatan mereka mengalami perubahan besar berikutan tempat penginapan beralih dari dalam gua ke ruang terbuka. – Agensi
