【進化】南太平洋民の先祖の顔復元 3千年前の頭骨で＝京大教授
1 ：科学屋さん φ ★：
南太平洋のフィジー諸島で発掘された約3000年前のものとみられる人の頭蓋(ずがい)骨
から復元した顔の像が完成し、フィジーのサウス・パシフィック大学がこのほど公開した。
骨は南太平洋の島々に住む人々の先祖とされるラピタ人のもので、ラピタ人の顔が復元さ
れたのは初めて。
この人骨は、同大学などの調査団が2002年半ばにフィジー中部の小島、モトゥリキ島の
集落跡を発掘中に発見。ソロモン諸島の方言で「真実」を意味する「マナ」と名付けられ、詳
しい分析のため京都大学霊長類研究所の片山一道(かたやま・かずみち)教授(現・大学院
理学研究科教授)に送られた。
同教授は三次元の計測などでデータを集め、合成樹脂の復顔像を完成させた。ラピタ人
の人骨は、それまでもパプアニューギニアやバヌアツで十数体が見つかっていたが、マナ
は保存状態が非常に良かったため、復顔が可能だったという。
片山教授らの分析によると、マナは40―60歳で死亡した女性で、身長は161―164センチ。
筋肉が発達し、少なくとも子供1人を出産したとみられる。
調査団を率いたサウス・パシフィック大学のパトリック・ナン教授は「復顔像は、フィジーに
最初に住んだ人々がどんな顔つきだったかを正確に描写しており、フィジーだけでなく他の
太平洋の島々の歴史にとっても重要だ」と強調。
片山教授は「ラピタ人の遺跡は結構あるが、人骨はあまり残っておらず、そのほとんどは
頭の骨がぼろぼろに壊れてしまっている。復顔によって南太平洋に最初に住んでいたラピ
タ人の実際の容ぼうや体形が認識できるようになった」と話している。

写真を見ると、親しみを感じるんだが…持っているＤＮＡの叫びだろうか…
優しい母親だったろう。
