Bio Computer

Speculation: Your Body is a DNA computer.
Not 0/1 but base pairs G/C, A/T that denature at different temps. The Sun was the first programer.

Four Types of Aliens?

October 1, 2019

There may be only Four Types of Aliens

Start with this likely premise. Life starts the same way as it did on Earth and it’s based on carbon chemistry.

That means it most likely requires the following:

1. Liquid water.
2. Temperature range that allows for liquid water, 0-100 C
3. Earth size gravity that holds in the correct atmosphere and gases needed to start life.
4. Plate tectonics and land to allow for a shoreline.
5. Sun/star to provide heat in a day night cycle.
6. Natural selection that leads to the type of social behavior that leads to high intelligence.

Those requirements suggest that life planets will have most of these 4 basic biomes; water, air, land, underground.

Convergent evolution suggests that there are basically 4 ways to best survive those 4 environments.

That means that advanced aliens are either:
1. Swimmers – like advanced dolphins or sea dwellers
2. Flyers – like advance birds or air dwellers
3. Walkers – like advanced hominids or land dwellers
4. Burrowers – like advanced gophers or underground dwellers.

Comments? For more speculation, see my two sci-fi novels.

Fitness of LIfe as 3 separate parts.

March 15, 2019

Reading this, George Gaylord Simpson said that the only goal he could find in life was that it expands across the planet. That got me to refine my suggestion of these three goals for all life:

Life evolves to each species’ highest fitness in 3 categories, 1. nurturing self, 2. protecting self, and 3. sexual reproduction success. Then it stays in stabilizing selection, until something changes and selection pressure forces it to adapt to the new condition.
That, if true, opens up a lot of new ideas.

Why Will Aliens Look Like Earthlings!

December 13, 2018

Why will ALIENS almost surely look like EARTHLINGS?

Two words, CONVERGENT EVOLUTION – in this case it works for two planets!

For life to start there must be a planet in the Goldilocks zone. That includes a temperature range that allows for liquid water.

But it must also have a certain atmosphere.
When the planet is too big, like Jupiter, it has the wrong atmosphere. When the planet is too small, like our Moon, it doesn’t hold in an atmosphere. Wrong atmosphere, wrong chemistry – no life.

That means that life planets always have THE SAME GRAVITY!

That means that the life on those watery planets with the same gravity will have life that faces the same natural selection as our planet.

That means that life anywhere will evolve to the best ways to: SWIM, WALK, FLY, and BURROW!

Convergent evolution means they will come up with virtually the same solutions to how to best swim, walk, fly, and burrow, that life did on Earth.

SO, if aliens are ever found, they should be much the same as life on Earth – CONVERGENT EVOLUTION!

The Origin of Life… IF

July 23, 2018

Concerning the origin of life:

IF life was hard to start,
it’s most likely that we are NOT here!

IF life was easy to start,
it’s most likely that we ARE here!
