Imagine being able too trace the evolutionary history of life on Earth, deciphering the intricate tapestry of genetic changes that have shaped the diversity we see today.
Researchers at the University of California San Diego, led by electrical engineers, have developed a powerful new tool that makes this ambitious dream closer to reality. Their innovative method, called CASTER, allows for the complete analysis of entire genomes, opening up unprecedented possibilities for understanding how species are related and how evolution has unfolded over time.
Published in the prestigious journal Science on january 23, 2025, the groundbreaking research paves the way for a deeper understanding of the tree of life. As the number of sequenced genomes, both from living and extinct species, continues to skyrocket, CASTER provides a much-needed solution for comparing these vast amounts of genetic data.
“Since the early 2000s, countless studies have claimed ‘genome-wide’ phylogeny reconstruction; however, these have been all based on subsampling regions scattered across the genomes, totalling only a small fraction of each full genome that is part of any given study.Analyzing all genomic positions while using complex models had seemed out of reach,” explains Siavash Mirarab, an electrical engineering professor at UC San Diego and the corresponding author of the study in Science. “What excites me is that we can now perform truly genome-wide analyses using every base pair aligned across species wiht widely available computational resources.”
This advancement represents a paradigm shift in the field of genomics. Traditionally, researchers have relied on analyzing only small snippets of DNA, limiting their understanding of evolutionary relationships. CASTER, however, can analyze the entire genome, providing a more complete and accurate picture of how different species are related.
The development of CASTER wasn’t solely the work of engineers. Chao Zhang, the first author on the Science paper and a former PhD student in the Bioinformatics and Systems Biology programme at UC San Diego, emphasizes the importance of interdisciplinary collaboration.
“arriving at this milestone required combined efforts from many disciplines, including statistics, computer science, and biology,” says Zhang, who is now a faculty member at the University of Copenhagen.
CASTER empowers biologists to unlock a wealth of evolutionary secrets. By analyzing the entire genome, researchers can identify regions that have been conserved across species, pinpointing crucial genes involved in essential biological processes. They can also pinpoint regions that have undergone rapid changes, shedding light on the genetic basis of adaptation and speciation.
The implications of CASTER are profound, extending far beyond the realm of theoretical biology. This powerful tool has the potential to revolutionize our understanding of everything from the origins of life to the development of new antibiotics and treatments for genetic diseases.

Unlocking the Secrets of Evolution: An Interview with Dr.Siavash Mirarab
Archyde News: Dr. Mirarab, your team at UC San Diego has developed a groundbreaking new method called CASTER, which allows for the complete analysis of entire genomes.Can you tell us more about this innovation and what makes it so revolutionary?
Dr.Siavash Mirarab: Absolutely. CASTER, which stands for Comparative Analysis of Single-nucleotide Evolution across Traits and Species, is a computational tool that allows us to analyze every single base pair across an entire genome when comparing different species. This stands in contrast to previous methods, which relied on analyzing only small snippets of DNA.
Imagine it like trying to understand a complex novel by only reading a few scattered sentences. CASTER lets us read the entire text, providing a much richer and more accurate understanding of the evolutionary relationships between organisms.
Archyde News: You mention that CASTER is “genome-wide.” What does that mean in practical terms for evolutionary biologists? What kind of insights can they gain from this new approach?
Dr. Mirarab: It means we can now identify regions of the genome that have been conserved across vast stretches of evolutionary time. These conserved regions frequently enough contain genes essential for core biological processes, providing valuable clues about the core mechanisms underlying life itself. Additionally, CASTER can pinpoint regions that have undergone rapid changes, shedding light on the genetic basis of adaptation, speciation, and the emergence of new traits.
Archyde News: The research paper published in Science highlights the importance of interdisciplinary collaboration in this breakthrough. Can you elaborate on the different disciplines that came together to make CASTER a reality?
Dr. Mirarab: It truly was a team effort. Chao Zhang, who lead the advancement of CASTER, brought together expertise in bioinformatics, statistics, computer science, and evolutionary biology.We realized that solving this complex problem required a diverse set of perspectives and skill sets, and the collaborative surroundings at UC San Diego provided the perfect breeding ground for this kind of innovation.
Archyde News: What do you see as the long-term implications of CASTER? Where do you envision this technology taking us in the future of evolutionary biology and beyond?
Dr. Mirarab: The possibilities are truly exciting. I see CASTER revolutionizing our understanding of the tree of life,shedding light on the origins of biodiversity,and informing our understanding of things like antibiotic resistance and the emergence of novel diseases. Even areas like agricultural science could benefit from a deeper understanding of genetic relationships between crop species. Ultimately, CASTER empowers us to decipher the intricate “code of life” and gain a deeper appreciation for the interconnectedness of all living things.
Archyde News: This is a truly remarkable development with far-reaching implications. What’s next for the CASTER project?
Dr. Mirarab: We are actively working on improving the speed and efficiency of CASTER, making it even more accessible to researchers around the world. We are also exploring its application to a wide range of datasets, from ancient DNA to microbial genomes. We envision CASTER becoming a standard tool in the genomics toolkit, driving groundbreaking discoveries for years to come.
Archyde news: Thank you for your time,Dr. Mirarab.
Dr. Mirarab: It was a pleasure. I hope CASTER can provide a powerful lens through which to explore the wonders of evolution.
