Winston Ewert discusses the dependency graph of life

In a 2018 article which merits continued discussion: This hypothesis postulates that different biological species share modules related by a dependency graph. We evaluate several predictions made by this model about both biological and synthetic data, finding them to be fulfilled. Read More ›

Podcast: Winston Ewert on the Dependency Graph vs. Darwin’s Tree of Life, Part 1

Here: On this episode of ID the Future, guest host Robert J. Marks talks with Dr. Winston Ewert about Ewert’s groundbreaking new hypothesis challenging Darwin’s common descent tree of life. The new model is based on the well-established technique of repurposing software code in different software projects. Ewert, a senior researcher at Biologic and the Evolutionary Informatics Lab, describes the nested hierarchical pattern of life and how any credible theory of life’s origin and diversity must explain it. He then describes how Darwin’s basic theory fits, and doesn’t fit, the pattern, and the various ancillary mechanisms invoked to close the gaps. These patches include horizontal gene transfer, convergent evolution, and incomplete lineage sorting. Ewert then cues up what he argues Read More ›

Winston Ewert on his dependency graph model of the relationship of life forms

Programmer Winston Ewert has developed a dependency graph, as an alternative to the Darwinian “tree of life,” to understand relationships among life forms. Here he discusses it with Jonathan McLatchie: Dr. Winston Ewert … proposes an alternative model to common descent to explain the hierarchical classification of life. Based on his paper published in Bio-Complexity, available here. Note: Winston Ewert, who works at the Evolutionary Informatics Lab, is an author of Introduction to Evolutionary Informatics See also: Evolutionary informatics: A simplified explanation of Winston Ewert’s dependency graph and New “fixed” bacterial Tree of Life looks like a cityscape seen from below

Evolutionary informatics: A simplified explanation of Winston Ewert’s dependency graph

From Cornelius Hunter at Evolution News and Science Today: A recent paper in the journal BIO-Complexity, authored by Winston Ewert, uses a dependency graph approach to model the relationships between the species. This idea is inspired by computer science which makes great use of dependency graphs for packaging of software and optimization of software architecture. Complicated software applications typically use a wealth of lower level software routines. These routines have been developed, tested, and stored in modules for use by higher level applications. When this happens the application inherits the lower-level software and has a dependency on those modules. … What Ewert has developed is a model to explain the pattern of similarities in different organisms that mimics how computer Read More ›
