- Evidence of life found in 2.5 billion year old ruby
- A team of researchers from the University of Waterloo in Canada discovered life in ancient rubies
- Likely to be related to dead microorganisms such as cyanobacteria
An ancient ruby has been discovered by a team of researchers from the University of Waterloo in Canada. It is being claimed that this 2.5 billion year old Russian was once a part of ancient life. The researchers’ analysis and findings have been published in the journal Ore Geology Reviews. The research was carried out by a team of seven researchers led by Chris Yakimchuk, Professor of Earth and Environmental Sciences at Waterloo.
Team tested Ruby’s sample
This team studied the conditions and many nuances of geology necessary for the formation of rubies. He also looked at the rare ruby found in Greenland, the oldest fossil ever found. The team also tested a sample of ruby that found graphite, a mineral made from pure carbon. On this basis, the research team has claimed that graphite is a remnant of early life.
Also looked at the isotope composition of the carbon atom
The team also studied the property of isotope composition of the carbon atom. This measured the relativity between individual carbon atoms. In a statement, the research team said that more than 98 percent of all carbon atoms have 12 atomic mass units. Apart from this, there are also some carbon atoms that come with a mass of 13 or 14 atomic mass units.
Presence of Cyanobacteria in Ruby
Professor Chris Yakimchuk said in a statement that most of the lighter carbon atoms in living matter are because they take less energy to be incorporated into the cytoplasm. However, based on the increased amount of carbon-12 in the graphite found inside the ruby, scientists have claimed that the carbon atoms were once related to ancient life. Most likely it is related to dead microorganisms such as cyanobacteria.
Ruby is 2.5 billion years old
The study also noted that the graphite found in the rocks is estimated to be more than 2.5 billion years old. During that ancient time, oxygen in the atmosphere was not as abundant as it is today. At that time life existed only in microorganisms and algae. Yakimchuk said that the graphite found inside the ruby is truly unique. However, this is the first time that evidence of ancient life has been found inside a ruby.
