Merging systems biology and evolutionary biology to understand early life on Earth
Jason Raymond, University of California - Merced

Particularly in the last decade, high throughput sequencing of genomes and metagenomes has revolutionalized our understanding of biological diversity. These enormous, and continually growing, repositories of genetic information provide unprecedented opportunities to observe and refine our knowledge of the mechanisms of evolution. Our research is developing systems biological tools for analyzing the genetic, genomic, and metabolic repertoires of organisms and communities, and understanding how these have been shaped by 3.8 billion years of co-evolution with our planet. In particular, we are focusing on how the introduction of oxygen into Earth’s atmosphere beginning 2.4 billion years ago—the result of a biological process (photosynthesis)—fundamentally changed the trajectory of biological evolution and paved the way for the development of complex life.

    What shapes the questions asked by scientific researchers?
    As part of the series A Portrait of a Question, this short documentary explores Dr. Kevin McGhee's interest in schizophrenia and how fruit flies can help identify some of the genetic factors behind this brain disorder.
