Very interesting discovery in South Africa of a single species ecosystem. Makes me wonder how long that ecosystem has existed for though. Would be a perfect test bed for evolution if they were to monitor it for a period of time (days, months, years, decades) and see what – if any – mutations occur. Problem now may be that they’ve already introduced ‘foreign’ and new bacteria through contamination.
