我们研究了在过热的水热环境中化学演化的可能性，并发现在250摄氏度及以上的甘氨酸，丙氨酸，缬氨酸和天冬氨酸的混合物形成的微球。微球在较低温度下不形成，并且由硅酸盐和含有酰亚胺键和具有丰富缬氨酸的氨基酸残基的肽样聚合物组成。结果表明，嗜热细胞结构的可能性，这可能是采取的极端嗜热生物，如果它们存在，由Baross和德明报告。
We examined the possibility of chemical evolution in superheated hydrothermal environments and found the formation of microspheres at 250 degrees C and above from a mixture of glycine, alanine, valine, and aspartic acid. The microspheres did not form at lower temperatures and consisted of silicates and peptide-like polymers that contained imide bonds and amino acid residues having an abundance of valine. The results show the possibility of thermophilic cellular structures, which might be adopted by the extremely thermophilic organisms, if they exist, reported by Baross and Deming.
