One of the earliest thinkers of the modern age to postulate the potentials of artificial life, separate from [[artificial intelligence]], was math and computer prodigy [[John von Neumann]]. At the [[Hixon Symposium]], hosted by [[Linus Pauling]] in [[Pasadena, California]] in the late 1940s, von Neumann delivered a lecture titled "The General and Logical Theory of Automata." He defined an "automaton" as any machine whose behavior proceeded logically from step to step by combining information from the environment and its own programming, and said that natural organisms would in the end be found to follow similar simple rules. He also spoke about the idea of [[self-replicating machine]]s. He postulated a machine – a [[kinematic automaton]] – made up of a control computer, a construction arm, and a long series of instructions, floating in a lake of parts. By following the instructions that were part of its own body, it could create an identical machine. He followed this idea by creating (with [[Stanislaw Ulam]]) a purely logic-based automaton, not requiring a physical body but based on the changing states of the cells in an infinite grid – the first [[cellular automaton]]. It was extraordinarily complicated compared to later CAs, having hundreds of thousands of cells which could each exist in one of twenty-nine states, but von Neumann felt he needed the complexity in order for it to function not just as a self-replicating "machine", but also as a [[universal computer]] as defined by [[Alan Turing]]. This "[[Von Neumann universal constructor|universal constructor]]" read from a tape of instructions and wrote out a series of cells that could then be made active to leave a fully functional copy of the original machine and its tape. Von Neumann worked on his [[automata theory]] intensively right up to his death, and considered it his most important work. | One of the earliest thinkers of the modern age to postulate the potentials of artificial life, separate from [[artificial intelligence]], was math and computer prodigy [[John von Neumann]].

爱德华·摩尔(Edward F. Moore)提出了“人造活植物”的概念，这种植物是漂浮的工厂，它们可以创造自己的复制品。可以对它们进行程序设计，让它们发挥某些功能(提取淡水，从海水中提取矿物质)，与指数级增长的工厂才能带来巨大的回报相比，这项投资的规模相对较小。弗里曼·戴森(Freeman Dyson)也研究了这个想法，设想了可自我复制的机器被送去探索和开发其他行星和卫星，美国宇航局(NASA)一个名为“自我复制系统概念小组”(self- replication Systems Concept Team)的团队在1980年进行了一项关于在月球上自行建造工厂的可行性研究。

1970-1980年代
Philosophy scholar Arthur Burks, who had worked with von Neumann (and indeed, organized his papers after Neumann's death), headed the Logic of Computers Group at the University of Michigan. He brought the overlooked views of 19th century American thinker Charles Sanders Peirce into the modern age. Peirce was a strong believer that all of nature's workings were based on logic (though not always deductive logic). The Michigan group was one of the few groups still interested in alife and CAs in the early 1970s; one of its students, Tommaso Toffoli argued in his PhD thesis that the field was important because its results explain the simple rules that underlay complex effects in nature. Toffoli later provided a key proof that CAs were reversible, just as the true universe is considered to be.

曾与冯·诺依曼共事(事实上，在诺依曼去世后整理了他的论文)的著名学者亚瑟·伯克(Arthur Burks)领导了密歇根大学(University of Michigan)的“计算机逻辑小组”(Logic of Computers Group)。他把19世纪美国思想家查尔斯·桑德斯·皮尔斯（Charles Sanders Peirce）被忽视的观点带入现代。皮尔斯坚信自然界的一切活动都是基于逻辑的(尽管并不总是演绎逻辑)。 在20世纪70年代早期，密歇根大学的研究小组是少数几个仍然对生命和CAs感兴趣的研究小组之一;该小组的一名学生托马索·托福利(Tommaso Toffoli)在他的博士论文中指出，该领域非常重要，因为它的研究结果解释了自然界复杂效应背后的简单规则。托福利后来提供了一个关键的证据，证明CAs是可逆的，就像真正的宇宙被认为是可逆的一样。
Christopher Langton was an unconventional researcher, with an undistinguished academic career that led him to a job programming DEC mainframes for a hospital. He became enthralled by Conway's Game of Life, and began pursuing the idea that the computer could emulate living creatures. After years of study (and a near-fatal hang-gliding accident), he began attempting to actualize Von Neumann's CA and the work of Edgar F. Codd, who had simplified Von Neumann's original twenty-nine state monster to one with only eight states. He succeeded in creating the first self-replicating computer organism in October 1979, using only an Apple II desktop computer. He entered Burks' graduate program at the Logic of Computers Group in 1982, at the age of 33, and helped to found a new discipline.

克里斯托弗·兰顿（Christopher Langton）是一位非传统的研究者，他平凡的学术生涯让他找到了一份为一家医院编程DEC大型机的工作。他被康威的“生命游戏”迷住了，并开始追求计算机可以模仿生物的想法。经过多年的研究(和一次几乎致命的悬挂式滑翔事故)，他开始尝试实现冯·诺依曼的CA和埃德加·科德（Edgar F. Codd）的工作，后者将冯·诺依曼最初的29个状态怪物简化为只有8个状态。1979年10月，他仅用一台Apple II型台式电脑就成功地创造出了第一台能够自我复制的计算机有机体。1982年，33岁的他加入了伯克在计算机逻辑小组的研究生课程，并帮助建立了一门新的学科。

兰顿关于《人工生命》的官方会议公告是对这个之前几乎不存在的领域最早的描述:
Artificial life is the study of artificial systems that exhibit behavior characteristic of natural living systems. It is the quest to explain life in any of its possible manifestations, without restriction to the particular examples that have evolved on earth. This includes biological and chemical experiments, computer simulations, and purely theoretical endeavors. Processes occurring on molecular, social, and evolutionary scales are subject to investigation. The ultimate goal is to extract the logical form of living systems.

人工生命是对具有自然生命系统行为特征的人工系统的研究。它寻求解释生命的任何可能表现形式，而不局限于地球上已经演化出来的特殊例子。这包括生物和化学实验、计算机模拟和纯理论研究。发生在分子、社会和进化尺度上的过程需要进行研究。最终目标是提取出生命系统的逻辑形式。
Microelectronic technology and genetic engineering will soon give us the capability to create new life forms in silico as well as in vitro. This capacity will present humanity with the most far-reaching technical, theoretical and ethical challenges it has ever confronted. The time seems appropriate for a gathering of those involved in attempts to simulate or synthesize aspects of living systems.

Ed Fredkin founded the Information Mechanics Group at MIT, which united Toffoli, Norman Margolus, Gerard Vichniac, and Charles Bennett. This group created a computer especially designed to execute cellular automata, eventually reducing it to the size of a single circuit board. This "cellular automata machine" allowed an explosion of alife research among scientists who could not otherwise afford sophisticated computers.

In 1982, computer scientist named Stephen Wolfram turned his attention to cellular automata. He explored and categorized the types of complexity displayed by one-dimensional CAs, and showed how they applied to natural phenomena such as the patterns of seashells and the nature of plant growth.

Computer animator Craig Reynolds similarly used three simple rules to create recognizable flocking behaviour in a computer program in 1987 to animate groups of boids. With no top-down programming at all, the boids produced lifelike solutions to evading obstacles placed in their path. Computer animation has continued to be a key commercial driver of alife research as the creators of movies attempt to find more realistic and inexpensive ways to animate natural forms such as plant life, animal movement, hair growth, and complicated organic textures.

1987年，计算机动画师克雷格·雷诺兹（Craig Reynolds）同样使用三个简单的规则在一个计算机程序中创建了可识别的群集行为。由于完全没有自顶向下的编程，群集体产生了类似生命体的解决方案，以避开摆在他们道路上的障碍。计算机动画一直是人工生命研究的主要商业驱动力，因为电影的创作者试图寻找更现实和廉价的方式，来使自然形式如植物、动物运动、毛发生长和复杂的有机材质等具有生命力。
J. Doyne Farmer was a key figure in tying artificial life research to the emerging field of complex adaptive systems, working at the Center for Nonlinear Studies (a basic research section of Los Alamos National Laboratory), just as its star chaos theorist Mitchell Feigenbaum was leaving. Farmer and Norman Packard chaired a conference in May 1985 called "Evolution, Games, and Learning", which was to presage many of the topics of later alife conferences.

Farmer and Norman Packard chaired a conference in May 1985 called "Evolution, Games, and Learning", which was to presage many of the topics of later alife conferences.
多恩·法默（J. Doyne Farmer）是将人工生命研究与复杂自适应系统这一新兴领域联系起来的关键人物，他在非线性研究中心(洛斯阿拉莫斯国家实验室的一个基础研究部门)工作，就在其明星混沌理论学家米切尔·费根鲍姆即将离开的时候。1985年5月，法默和诺曼·帕卡德（Norman Packard）主持了一个名为“进化、游戏和学习”的会议，这预示了后来的人工生命会议的许多主题。

On the ecological front, research regarding the evolution of animal cooperative behavior (started by W. D. Hamilton in the 1960s 引用错误：没有找到与</ref>对应的<ref>标签[7][8] resulting in theories of kin selection, reciprocity, multilevel selection and cultural group selection) was re-introduced via artificial life by Peter Turchin and Mikhail Burtsev in 2006. Previously, game theory has been utilized in similar investigation, however, that approach was deemed to be rather limiting in its amount of possible strategies and debatable set of payoff rules. The alife model designed here, instead, is based upon Conway's Game of Life but with much added complexity (there are over 101000 strategies that can potentially emerge). Most significantly, the interacting agents are characterized by external phenotype markers which allows for recognition amongst in-group members. In effect, it is shown that given the capacity to perceive these markers, agents within the system are then able to evolve new group behaviors under minimalistic assumptions. On top of the already known strategies of the bourgeois-hawk-dove game, here two novel modes of cooperative attack and defense arise from the simulation.

在此之前，博弈论被用于类似的研究，然而，该方法被认为是数量相当有限的可能策略和有争议的支付规则集。相反，这里设计的人工生命模型是基于康威的生命游戏，但增加了很多复杂性(可能会出现超过101000种策略)。最重要的是，相互作用的因子具有外部表型标记，可在组内成员之间识别。实际上，它表明，如果有能力感知这些标记，系统内的因子就能够在最简假设下进化出新的群体行为。在已知的资产阶级-鹰派-鸽派对策策略之上，这里有两种新颖的合作攻击和防御模式从模拟中产生。
For the setup, this two-dimensional artificial world is divided into cells, each empty or containing a resource bundle. An empty cell can acquire a resource bundle with a certain probability per unit of time and lose it when an agent consumes the resource. Each agent is plainly constructed with a set of receptors, effectors (the components that govern the agents' behavior), and neural net which connect the two. In response to the environment, an agent may rest, eat, reproduce by division, move, turn and attack. All actions模板:Clarify expend energy taken from its internal energy storage; once that is depleted, the agent dies. Consumption of resource, as well as other agents after defeating them, yields an increase in the energy storage. Reproduction is modeled as being asexual while the offspring receive half the parental energy. Agents are also equipped with sensory inputs that allow them to detect resources or other members within a parameter模板:Clarify in addition to its own level of vitality. As for the phenotype markers, they do not influence behavior but solely function as indicator of 'genetic' similarity. Heredity is achieved by having the relevant information be inherited by the offspring and subjected to a set rate of mutation.

对于该设置，这个二维人工世界被划分为单元，每个单元为空或包含一个资源包。一个空单元可以获得单位时间内一定概率的资源包，并在因子消耗该资源时丢失它。每个因子都是由一组受体、效应器(控制因子行为的组件)和连接两者的神经网络构成的。为了对环境做出反应，个体可以休息、进食、分裂繁殖、移动、转身和攻击。所有的动作消耗的能量来自于它的内部能量储存;一旦耗尽，因子就会死亡。消耗资源，以及击败其他因子后，产生能量储存的增加。繁殖模式为无性繁殖，其后代获得双亲能量的一半。因子还配备了感官输入，允许它们检测一个参数内除了它自己活力水平以外的资源或其他成员。至于表型标记，它们并不影响行为，而仅仅作为“遗传”相似性的指标。遗传是通过让后代继承相关的信息并承受一定的突变率来实现的。
The objective of the investigation is to study how the presence of phenotype markers affects the model's range of evolving cooperative strategies. In addition, as the resource available in this 2D environment is capped, the simulation also serves to determine the effect of environmental carrying capacity on their emergence.

本研究旨在探讨表型标记的存在对模型合作策略演化范围的影响。此外，由于该二维环境的可用资源是有限的，模拟还可以确定环境承载力对其涌现的影响。
One previously unseen strategy is termed the "raven". These agents leave cells with in-group members, thus avoiding intra-specific competition, and attack out-group members voluntarily. Another strategy, named the 'starling', involves the agent sharing cells with in-group members. Despite individuals having smaller energy storage due to resource partitioning, this strategy permits highly effective defense against large invaders via the advantage in numbers. Ecologically speaking, this resembles the mobbing behavior that characterizes many species of small birds when they collectively defend against the predator.

一种前所未见的策略被称为“乌鸦”。这些因子使细胞与群内成员共存，从而避免了群内竞争，并主动攻击群外成员。另一种名为“starling”的策略是让因子与组内成员共享细胞。尽管由于资源分割，个体拥有较小的能量存储，但这种策略可以通过数量上的优势，对大型入侵者进行高效防御。从生态学的角度来说，这类似于许多小型鸟类在集体防御捕食者时所具有的聚众滋扰行为。
In conclusion, the research claims that the simulated results have important implications for the evolution of territoriality by showing that within the alife framework it is possible to "model not only how one strategy displaces another, but also the very process by which new strategies emerge from a large quantity of possibilities".[9]

总之，研究认为，模拟结果表明，在人工生命框架内，“不仅可以模拟一种战略如何取代另一种战略，而且可以模拟新战略从大量可能性中产生的过程”，从而对地域性的演变具有重要意义。
Work is also underway to create cellular models of artificial life. Initial work on building a complete biochemical model of cellular behavior is underway as part of a number of different research projects, namely Blue Gene which seeks to understand the mechanisms behind protein folding.
