Understanding Evolution: Debunking the Illusion of Measurement

The concept of how evolved something is often leads to confusion and misunderstanding. It is a question that lacks logical foundation and is frequently misunderstood. In this article, we will explore the true nature of evolution, the ways in which it is measured, and why it is not a meaningful concept to assess.

The Nature of Evolution and Adaptation

The adaptation of organisms to their environment is a core principle of evolution. However, the idea of ranking the 'evolutionary progress' of one organism over another is nonsensical. Any organism that is well adapted to its environment is said to be evolved. This means that an earthworm is as evolved as a human, since both are well adapted to their respective environments.

Evolution does not have a termination point. As long as a species or a form of life exists, it continues to evolve, adapting to changing conditions over time. The current state of biodiversity on our planet is a snapshot of life at this moment, but we cannot predict exactly what it will look like in the future. In 100,000 years, the animals we see today may evolve into forms that are unrecognizable to us.

Measurement of Evolution

While the concept of 'how evolved' is meaningless, there are two ways to measure evolution:

1. Time

The duration of evolutionary processes is a straightforward and reliable measure. If an organism is still alive today, it has undergone the same amount of evolution as every other living organism that is still present. This principle applies to all species, regardless of their complexity or perceived level of advancement.

2. Genetics

The genetic makeup of organisms provides another way to measure evolution. Genomes carry the instructions for building an individual organism. Over time, as species evolve, their genomes can accumulate changes, including the addition of new genes. A species with a longer genome sequence has undergone more evolutionary changes than a species with a shorter sequence.

Examples of Genetic Changes

To illustrate the genetic aspect of evolution, consider humans and the Japanese flower Paris japonica. Humans have about 32 billion gene pairs in our genome. In contrast, the Paris japonica has an astonishing 149 billion gene pairs, making it roughly 50 times more genetically complex than humans. From this perspective, one could say that Paris japonica is more 'evolved' in terms of genetic changes, but this does not reflect a superiority in adaptation to the environment.

Adaptation and the Limits of Evolution

It is important to recognize that evolutionary adaptation is not always sufficient to ensure survival under all circumstances. For example, humans are not well-adapted to desert environments, and climate change could make these regions uninhabitable even for highly evolved forms of life like us. The concept of a finite, advanced stage of evolution is a misconception; there is always room for improvement, as evolution is an ongoing process.

In conclusion, the idea of 'how evolved' an organism is does not exist and is a misleading concept. The key to understanding evolution lies in grasping the continuous nature of the process and the ways in which it can be measured through time and genetics. Evolution is a dynamic, ever-evolving phenomenon, and the framework within which species adapt to their environments is its true form.
