美國國家科學院網(wǎng)站（NationalAcademyofScienceswebsite）新公布的一項研究成果表明：在早太古代（EarlyArcheanperiod）,，地球的早期生命可能來自于格陵蘭島的Isua超級地殼帶（SupercrustalBelt）。
太古代是我們地球地質(zhì)發(fā)展史中非常古老的一段時期,，大約為距今40到25億年前,，是地球巖石圈,、水圈、大氣圈和生命形成非常關鍵而又漫長的時期,。
科學家最新的研究發(fā)現(xiàn),，在格陵蘭島Isua超級地殼帶的深海火山泥中研究人員檢測到了所有氨基酸（aminoacid）形成所必需的化學成分,。在太古代時期這里的一些有機物組成,，金屬物質(zhì)含量和環(huán)境溫度都顯示這里的環(huán)境條件非常有利于氨基酸的形成,，同時鋅組分的化石結(jié)構(gòu)研究也表明其很可能對氨基酸的形成具有一定的催化作用。
氨基酸是含有氨基和羧基的一類有機化合物的通稱,，是生物功能大分子蛋白質(zhì)的基本組成單位,，是構(gòu)成動物營養(yǎng)所需蛋白質(zhì)的基本物質(zhì)。也就是說找到早期地球氨基酸形成的潛在證據(jù)是認識地球早期生命起源和發(fā)展非常重要的關鍵所在,。
同時海底的極端環(huán)境也被認為是該理論中氨基酸形成另外的一個觸發(fā)因素,。也就是說生命很可能開始于類似格陵蘭島當時的環(huán)境，或者是在化學組成和環(huán)境都有利于產(chǎn)生氨基酸的地方,。（生物谷 Bioon.com）

Early Archean serpentine mud volcanoes at Isua, Greenland, as a niche for early life

The Isua Supracrustal Belt, Greenland, of Early Archean age (3.81–3.70 Ga) represents the oldest crustal segment on Earth. Its complex lithology comprises an ophiolite-like unit and volcanic rocks reminiscent of boninites, which tie Isua supracrustals to an island arc environment. We here present zinc (Zn) isotope compositions measured on serpentinites and other rocks from the Isua supracrustal sequence and on serpentinites from modern ophiolites, midocean ridges, and the Mariana forearc. In stark contrast to modern midocean ridge and ophiolite serpentinites, Zn in Isua and Mariana serpentinites is markedly depleted in heavy isotopes with respect to the igneous average. Based on recent results of Zn isotope fractionation between coexisting species in solution, the Isua serpentinites were permeated by carbonate-rich, high-pH hydrothermal solutions at medium temperature (100–300 °C). Zinc isotopes therefore stand out as a pH meter for fossil hydrothermal solutions. The geochemical features of the Isua fluids resemble the interstitial fluids sampled in the mud volcano serpentinites of the Mariana forearc. The reduced character and the high pH inferred for these fluids make Archean serpentine mud volcanoes a particularly favorable setting for the early stabilization of amino acids.
