There's a, there's definitely more than oxygen, than the rise of oxygen on thise planet. Methangens are quite ina, sort of a they were running to show and lato aammonia, ammona oxidizing. Right later on, thes bacteria showed up. But we know that the photo synthesis definitely played a isignificant role in the composition of the atmosphere. Yet we really know almost nothing about whenit to the ancient planets biomas.

In the question to understand the biology of life, we are (so far) limited to what happened here on Earth. That includes the diversity of biological organisms today, but also its entire past history. Using modern genomic techniques, we can extrapolate backward to reconstruct the genomes of primitive organisms, both to learn about life’s early stages and to guide our ideas about life elsewhere. I talk with astrobiologist Betül Kaçar about paleogenomics and our prospects for finding (or creating!) life in the universe.
