# Impact in innovation is analogous to fitness in evolution
Evolutionary fitness is affected by
1. Other species
* These tend to get killed out at the population level
2. The environment
* These tend to get killed out at the individual level (unless they were suited to the environment and the environment itself changed which would cause a die out at the population level)
3. Endogenous factors (like if a mutant had a tiny heart that couldn't pump blood to its brain.)
* These tend to get killed out at the developmental stage (ie in utero) or very soon after birth.
Similarly, technological fitness is affected by
1. Other technologies
* If a technology is strictly worse than another technology on all factors, it won’t be used. However, there are often some niches where it can survive.
2. The environment
* In the simplest case
3. Endogenous factors
This raises a number of questions
* Has anyone ever created a precise definition of evolutionary fitness?
In the same way that neither a genotype or phenotype will predict whether a species will do well, [[A heuretic’s impact is not endogenous to the technology but depends on the environment]].
[[Self-Organized Criticality: An Explanation of 1 over f Noise]] shows why both evolutionary processes and technological processes exhibit punctuated equilibria.
