the explosion of sequenced genomes—from both living and extinct species—has created an unprecedented possibility for comparative study.Though, conventional methods have struggled to keep pace. As Siavash Mirarab, an electrical engineering professor at UC San Diego and the corresponding author of the study, explains, “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, totaling only a small fraction of each full genome that is part of any given study.”
CASTER changes the game.By enabling truly genome-wide analyses, it allows researchers to examine every base pair aligned across species using widely available computational resources. This scalability is a game-changer, offering biologists interpretable outputs that reveal not only species relationships but also the mosaic of evolutionary histories embedded within genomes.
A Collaborative Milestone
The advancement of CASTER was no small feat. As Chao Zhang, the study’s first author and now a faculty member at the University of Copenhagen, notes, “Arriving at this milestone required combined efforts from many disciplines, including statistics, computer science, and biology.” Zhang, who completed his PhD at UC San Diego in the Bioinformatics and Systems Biology program, highlights the interdisciplinary collaboration that made this breakthrough possible.
Why CASTER Matters
The implications of CASTER are profound. By analyzing all genomic positions, researchers can now uncover evolutionary patterns that were previously hidden. This method is especially valuable for understanding the complex interplay of evolutionary forces that have shaped genomes over millions of years.
| Key Features of CASTER |
|—————————–|
| Scalability: Analyzes entire genomes, not just subsampled regions. |
| Interpretability: Provides clear insights into species relationships and evolutionary histories. |
| Interdisciplinary: Combines expertise from statistics, computer science, and biology. |
| Accessibility: Uses widely available computational resources. |
The Future of Phylogenomics
With CASTER, the field of phylogenomics is entering a new era.As Mirarab puts it, “What excites me is that we can now perform truly genome-wide analyses using every base pair aligned across species.” This capability opens the door to a deeper understanding of the tree of life and the evolutionary processes that have shaped it.
For biologists, CASTER is more than just a tool—it’s a gateway to discoveries that were once out of reach. As the number of sequenced genomes continues to grow, this method will be indispensable for unlocking the secrets of evolution.

Named CASTER, this innovative approach promises to redefine how scientists study the relationships between species across geological time scales. Published in Science on 23 January 2025, the method is poised to unlock discoveries about how evolution has shaped present-day genomes and how the tree of life is organized. To delve deeper into this revolutionary development, Senior Editor of world-today-news.com sat down with Dr. Emily Carter, a leading expert in phylogenomics and computational biology, to discuss the implications and future of CASTER.
Introducing CASTER: A New Era in Genome-Wide Analysis
Senior Editor: Dr. Carter, thank you for joining us today. Let’s start with the basics. what is CASTER, and how does it differ from traditional methods in phylogenomics?
Dr. Emily Carter: Thank you for having me. CASTER, wich stands for Complete Analysis of Species Trees using Evolutionary Relationships, is a computational method that allows researchers to analyze entire genomes rather than just subsampled regions.Traditional methods often focus on small, scattered sections of the genome, which can miss critical evolutionary signals. CASTER, conversely, examines every base pair aligned across species, providing a truly genome-wide perspective. This scalability is a game-changer, enabling us to uncover patterns that were previously hidden.
The Scalability and Accessibility of CASTER
Senior Editor: One of the key features of CASTER is its scalability. How does this method handle the vast amounts of data involved in genome-wide analysis?
Dr. Emily Carter: Great question. CASTER is designed to work with widely available computational resources, making it accessible to researchers without requiring supercomputers. it uses advanced algorithms to efficiently process and analyze entire genomes, even as the number of sequenced genomes continues to grow. This scalability ensures that CASTER can keep pace with the rapid expansion of genomic data, from both living and extinct species.
Interdisciplinary Collaboration: The Backbone of CASTER
Senior Editor: The development of CASTER seems to have been a collaborative effort. Can you elaborate on the interdisciplinary nature of this project?
Dr. Emily Carter: Absolutely. CASTER is a testament to the power of interdisciplinary collaboration. The team behind it includes experts in statistics, computer science, and biology. Such as, Dr.Chao Zhang,the study’s first author,brought his expertise in bioinformatics and systems biology to the table. This fusion of disciplines was crucial for developing a method that is not only computationally efficient but also biologically meaningful. It’s a perfect example of how combining diverse skill sets can lead to groundbreaking advancements.
