Incomplete genome sequence from the planet Earth reveals an ancient history of life on the planet, scientists have said.
The study, published in the journal Nature, provides a first glimpse of how the Earth’s ancient DNA has evolved, and it shows that some species have undergone genetic changes that are consistent with an ancient biochemistry, such as the production of sugars.
The researchers also looked at the genetic material of ancient humans from around the world.
The team’s analysis revealed that humans were a diverse group of organisms that evolved over hundreds of thousands of years, and had undergone some significant changes in their genomes over time.
The ancient DNA sequence, which was published on Thursday, was carried out using the Illumina MiSeq platform, a technology developed by Illumina that can scan and analyse DNA in a wide variety of samples.
It has already revealed that human genomes from Africa, Asia, Europe and the Americas have undergone some genetic changes and mutations, including mutations that are associated with the production and storage of carbohydrates, protein and RNA, and changes that have altered the chemical structures of DNA.
The new study also revealed that the genomes of many other ancient species, including whales, elephants and dolphins, have undergone similar changes to those found in the ancient genomes of humans.
This indicates that some of these ancient species have become adapted to survive on the Earth, such that they have adapted to their environment.
This means that if humans evolved to survive in a harsh environment, we would expect to see a large proportion of their genes being modified to adapt to that environment, said Dr Pauline Tarrant, lead author of the study from the University of Exeter.
The paper suggests that this is the case, with changes in gene function that are likely to have occurred in an environment that was quite hostile.
“The finding that the ancient human genomes are not completely complete but do reveal some variation in gene expression provides an insight into how the ancient genome has changed over time,” said Professor David Riedel, lead investigator from the Department of Genetics at Imperial College London.
The discovery will allow scientists to better understand how life on Earth developed over time, and will also provide insights into how life could evolve on other planets.
It could help scientists to create more effective treatments for genetic diseases.
There are many other implications for the future of humanity.
Because we are so remote, we need to be careful in our thinking about what is happening here, said Professor Pauline, who is the co-author of the paper.
“It will be really exciting to see how the DNA we carry will change in the future.”
