Do most aliens live on land or in the ocean? | Robin Hanson and Lex Fridman

TL;DR

Evolution is more prominent on land due to the diverse environments and smaller species, while large systems, including biological and software systems, tend to decay over time. Ocean worlds may hold the potential for advanced life forms.

what percent of hello aliens evolved from land animals as opposed to plants or ocean slash air organisms by the way i did um recently see that there's uh only ten percent of species on earth are in the ocean so there's a lot more right variety on land there is it's interesting so why is that i don't even i can't even intuit exactly why that would b...

Key Insights

• ✋ Evolution is more prominent on land due to the higher variety of environments and the presence of smaller species.
• ⌛ Large systems, including software and biological systems, tend to decay and require replacement over time.
• 🌍 Ocean worlds may hold the potential for advanced life forms, as a large fraction of planets are believed to be ocean worlds.
• 💁 The assumption that our path of evolution is the only possibility may discount the potential for other forms of life on different paths.
• 🌍 The prevalence of ocean worlds increases the chances of finding advanced life on long-lasting planets.
• 🤗 The question of whether alien civilizations took their early steps on land or in the ocean is still open.
• 👽 Twitter polls do not represent objective truth, but they reflect the opinion that it is likely for alien civilizations to have begun on land.

Questions & Answers

Q: Why are there more species on land compared to the ocean?

The variety on land is higher due to the challenges of survival, the presence of small niches, and the ability for species to adapt to varying environments.

Q: How does speciation promote evolution?

Speciation occurs when multiple species exist, creating competition and leading to further evolutionary adaptations. This is more common on land and in rivers due to the variation in environments.

Q: Why do large systems decay over time?

Large systems, including software and biological systems, tend to decay due to the complexity and difficulties in maintaining and adapting such systems. This is known as "rot" and is a challenge faced by world governments, among others.

Q: Are large companies and economies more effective in evolving?

While large companies may have more resources, they often struggle to evolve effectively over long periods, with many dying out. However, large economies, such as cities or integrated nations, tend to grow better due to various factors.

Summary & Key Takeaways

• Only 10% of species on Earth are in the ocean, indicating a higher variety on land, possibly due to the challenges of survival on land and the presence of small niches.

• Speciation is promoted by having multiple species, which is more common on land and in rivers due to varying environments.

• Large systems, including software and biological systems, tend to decay over time, while smaller species and fragmented species allow for more effective evolution.
