Аннотация

Recent advancements in genome sequencing have revealed a vast diversity of protein families, yet the known functional families are minimal compared to all possible amino acid sequences. The proposal introduces EASME, merging evolutionary algorithms, machine learning, and bioinformatics to develop completely novel proteins. By simulating molecular evolution, EASME aims to expand the set of extant proteins by colonizing new islands in the sea of invalidity. The intersection of computational evolution and biology remains under-explored but holds promising discoveries for biotechnological applications. The focus on solving biological problems through EASME could lead to significant advancements in various fields such as agriculture and synthetic biology.

How can EASME contribute to understanding the origins of life beyond protein evolution?

EASME, through its focus on simulating molecular evolution using evolutionary algorithms (EAs), has the potential to shed light on the origins of life beyond just protein evolution. By evolving DNA-encoded proteins in silico and exploring new functional clades and protein families, EASME could provide insights into how early biomolecules may have evolved and interacted to form the first self-replicating cells. The ability to model complex biochemical systems computationally allows researchers to simulate processes that might have led to the emergence of the first biomolecules capable of self-replication.
Furthermore, by leveraging genetic programming within EAs, researchers can design novel peptides with specific functions, as demonstrated in projects like "A Genetic Programming Approach to Engineering MRI Reporter Genes." This approach could be extended to explore how primitive biomolecular structures may have developed functionalities crucial for early cellular processes. Ultimately, by uncovering grammar structures defining fundamental biological languages and simulating evolutionary pathways leading to functional molecules, EASME offers a unique opportunity to delve deeper into understanding the origins of life at a molecular level.

What are the limitations or drawbacks of solely relying on machine learning for complex biological problems?

While machine learning (ML) has made significant advancements in various fields, including biology and bioinformatics, there are inherent limitations when it comes to addressing complex biological problems independently. One key drawback is that ML models heavily rely on training data sets composed of existing functional proteins or sequences. These data sets are often biased towards known proteins from certain organisms or those involved in specific health-related issues. As a result, ML models struggle with generating true novelty in structure and function since they are limited by what nature has already provided.
Moreover, ML approaches typically operate as "black boxes," making it challenging for researchers to interpret why certain predictions or outcomes were made. Unlike evolutionary algorithms (EAs), which evolve solutions using predefined primitives and offer more explainable results due to their iterative selection process based on fitness criteria over generations.
In essence, while ML excels at pattern recognition within existing data sets and can yield impressive results based on correlations present in training data, it falls short when tasked with generating truly novel solutions outside the scope of its training set without a deep understanding of underlying biophysical principles governing biological systems.
