Episode notes

We are not once trying to generate an entire ancestral organism. We're just simply, in a mere modest way, trying to resurrect a three bin year old life its very but not the entire organism. So do want to fillin the gaps? Early on in our conversation, we talked about how maybe we have a handful of evidence of life in the past,. But such perhaps using the synthetic systems may enable us to fill in that gap, however artificial it is.

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.
