Живых микробов нашли в скале возрастом 2 миллиарда лет

ՀԱՆՐԱՀԱՅՏ ՄՈԼՈՐՈՒԹՅՈՒՆՆԵՐ

В запечатанной трещине породы возрастом 2 миллиарда лет ученые обнаружили скопления микробов. Фрагмент скалы был извлечен в вулканическом комплексе Бушвелд в Южной Африке. На данный момент это самый древний образец живых микробов, обнаруженных в доисторической породе.

Ученые применили три типа визуализации: инфракрасную спектроскопию, электронную микроскопию и флуоресцентную микроскопию. Это помогло доказать, что микроорганизмы действительно обитали в древнем керне, а не являются следствием современного загрязнения при извлечении.

Исследование микробов позволит лучше понять самые ранние этапы развития жизни на Земле. Кроме того, данные могут использовать при поиске внеземной жизни в образцах горных пород аналогичного возраста, доставленных с Марса, сообщает Microbial Ecology.

Ученые отметили, что колонии микробов выживают в горных породах в течение тысяч и даже миллионов лет. Очевидно, они живут в гораздо более медленном темпе и почти не эволюционируют, что дает исследователям возможность «заглянуть в прошлое».

«Изучая ДНК и геномы подобных микробов, мы, возможно, сможем понять эволюцию очень ранней жизни на Земле», – отметили эксперты.

Ранее сообщалось, что ученые пробурили самую глубокую в истории скважину. Исследование проводили у «Затерянного города» в Атлантическом океане.
