Emergence is the idea that new properties or behaviors can arise from the interactions of simpler components in a complex system. These emergent properties cannot be predicted from the properties of the individual components alone.

Supervenience is the idea that one property or phenomenon depends on another. For example, the color of an object supervenes on the physical structure of the object.

Emergence is a special case of supervenience in which the emergent property is novel and cannot be predicted from the properties of the individual components.

Emergence is a common phenomenon in biology. Some examples include the formation of multicellular organisms from single-celled organisms, the development of consciousness in humans, and the evolution of new species.

Supervenience is a common phenomenon in biology. Some examples include the color of an object supervening on the physical structure of the object, the behavior of an organism supervening on its genetic makeup and environment, and the function of an organ supervening on its structure.

Emergence and supervenience have a number of philosophical implications. They challenge the idea that the world is composed of simple, independent entities, suggest that the mind is not reducible to the brain, and support the idea that the whole is greater than the sum of its parts.

There are a number of criticisms of emergence and supervenience. Some critics argue that these concepts are vague and ill-defined, while others argue that they are not falsifiable and therefore not scientific. Still others argue that emergence and supervenience are incompatible with the laws of physics. However, none of these criticisms are universally accepted, and emergence and supervenience remain important concepts in philosophy of biology.

Emergence and reductionism are not necessarily incompatible. It is possible for a system to exhibit both emergent properties and reducible properties. For example, the behavior of an organism can be reduced to its genetic makeup and environment, but it can also exhibit emergent properties such as consciousness.

Emergence and holism are not necessarily incompatible. It is possible for a system to exhibit both emergent properties and holistic properties. For example, an organism can be considered a holistic entity, but it can also exhibit emergent properties such as consciousness.

There are a number of open questions about emergence and supervenience. Some of these questions include: What is the relationship between emergence and the laws of physics? How can emergent properties be explained in terms of the properties of the individual components? What are the implications of emergence and supervenience for the mind-body problem?

There are a number of future directions for research on emergence and supervenience. Some of these directions include: Developing new mathematical and computational models of emergence, investigating the relationship between emergence and the laws of physics, and exploring the implications of emergence and supervenience for the mind-body problem.

Emergence and supervenience have a number of practical applications. Some of these applications include: Developing new technologies that mimic emergent properties, understanding the complex behavior of biological systems, and designing new drugs and therapies that target emergent properties.

Emergence and supervenience have a number of ethical implications. Some of these implications include: The creation of artificial life raises ethical questions about the moral status of non-human entities, the development of new technologies that mimic emergent properties could have unintended consequences, and the use of drugs and therapies that target emergent properties could have unintended side effects.

There are a number of resources for learning more about emergence and supervenience. These resources include: Books and articles on emergence and supervenience, online resources such as websites and blogs, and conferences and workshops on emergence and supervenience.
