Significance Almost all organisms replicate by growing and then shedding offspring. Some molecules also replicate, but by moving rather than growing: They find and combine building blocks into self-copies. Here we show that clusters of cells, if freed from a developing organism, can similarly find and combine loose cells into clusters that look and move like they do, and that this ability does not have to be specifically evolved or introduced by genetic manipulation. Finally, we show that…

Motile Living Biobots Self-Construct from Adult Human Somatic Progenitor Seed Cells

Anthrobots are shown to be able to induce rapid repair of wounds in human neural cell sheets in vitro, and are a platform for learning about native cellular intelligence, and showing how life explores new ways of being.

Minimal Developmental Computation: A Causal Network Approach to Understand Morphogenetic Pattern Formation

This work shows how computation could occur in biological development and how machine learning approaches can generate hypotheses and deepen the understanding of how featureless tissues might develop sophisticated patterns—an essential step towards predictive control of morphogenesis in regenerative medicine or synthetic bioengineering contexts.

Competency of the Developmental Layer Alters Evolutionary Dynamics in an Artificial Embryogeny Model of Morphogenesis

It is observed that as competency of cells masks the raw fitness of the genomes, the phenotypic fitness gains are then mostly due to improvements of cells’ developmental problem-solving capacities, not the structural genome, suggesting the existence of a powerful ratchet mechanism.

Endless forms most beautiful 2.0: teleonomy and the bioengineering of chimaeric and synthetic organisms

It is suggested that a multi-scale competency architecture facilitates evolution of robust problem-solving, living machines and cybernetic perspectives on chimaeric morphogenesis erase artificial distinctions established by past limitations of technology and imagination.

Biological Robots: Perspectives on an Emerging Interdisciplinary Field

It is argued that as with computation, certain aspects of developmental biology and robotics are not tied to specific materials; rather, the consilience of these fields can help to shed light on issues of multi-scale control, self-assembly, and relationships between form and function.

Competency in Navigating Arbitrary Spaces as an Invariant for Analyzing Cognition in Diverse Embodiments

It is argued that the authors' innate capacity to recognize agency and intelligence in unfamiliar guises lags far behind their ability to detect it in familiar behavioral contexts, and the multi-scale competency of life is essential to adaptive function, potentiating evolution and providing strategies for top-down control to address complex disease and injury.

The Free Energy Principle drives neuromorphic development

We show how any system with morphological degrees of freedom and locally limited free energy will, under the constraints of the free energy principle, evolve toward a neuromorphic morphology that

Implications of Brain Evolution in Cetaceans and Primates for Highly Intelligent Extraterrestrial Life

If intelligent cetacean-like being evolved convergently in other worlds in response to aquatic habitats similar to Earth's, they would not be expected to have complex tools and technologies, whereas primate-like beings that may have evolved convergegently on other planets that are much older than Earth might have long ago developed technologies that surpass the authors' own.

A cellular platform for the development of synthetic living machines

A method for generation of in vitro biological robots from frog (Xenopus laevis) cells is reported, introducing a platform that can be used to study many aspects of self-assembly, swarm behavior, and synthetic bioengineering, as well as provide versatile, soft-body living machines for numerous practical applications in biomedicine and the environment.

Spontaneous Emergence of Self-Replicating Structures in Molecube Automata

A discrete, two-dimensional evolutionary simulation of large numbers of interacting robotic modules called “molecubes,” which were shown empirically to have self-replicating ability, bears strong resemblance to nonuniform cellular automata.

A scalable pipeline for designing reconfigurable organisms

This work presents a scalable pipeline for creating functional novel lifeforms: AI methods automatically design diverse candidate lifeforms in silico to perform some desired function, and transferable designs are then created using a cell-based construction toolkit to realize living systems with the predicted behaviors.

In this paper, the concept of self-replicating robots (SRRs) is reviewed, and the feasibility of a particular kind of minimalistic SRR is analyzed in the context of lunar resource development. The

Compositional pattern producing networks: A novel abstraction of development

Results produced with CPPNs through interactive evolution of two-dimensional images show that such an encoding can nevertheless produce structural motifs often attributed to more conventional developmental abstractions, suggesting that local interaction may not be essential to the desirable properties of natural encoding in the way that is usually assumed.

This work describes the autonomous self-replication of a reconfigurable string of parts from randomly positioned input components that, if suitably miniaturized and mass-produced, could constitute self-fabricating systems whose assembly is brought about by the parts themselves.

A survey of important advances in this biohybrid actuation paradigm is provided and it is suggested that the performance of living cells and tissues and directly interfacing them with artificial components should be possible to exploit the intricacy and metabolic efficiency of biological actuation within artificial machines.
