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.

Why Aliens will look like Earthlings

January 10, 2019

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!

Direction in Evolution

December 20, 2018

Read any biology text and it’ll say the same thing:

THERE IS NO DIRECTION TO EVOLUTION.
THERE IS NO DIRECTION TO NATURAL SELECTION.

But I say that is WRONG. I say there is a direction to evolution, and I think that once I tell you, you will agree and prove the textbooks are not correct.

The process of evolution always goes toward better CATABOLIC, and, ANABOLIC processes.

Natural selection does not select worse CATABOLIC, or ANABOLIC processes..

(This is also in my sci-fi novel, “Writings In Science, a History of the Future.”)

Take this further:

Mutation that is positive to a catabolic process will enhance anabolic processes.
Mutation that is negative to a catabolic process will be mitigated by anabolic processes – and vice versa. So not only is there a direction to evolution, but there is support from the other half of the catabolic or anabolic processes when mutations happen.

Natural Selection Part 2:

October 23, 2018

This link is from Science Daily

The title is:
For preterm infants, skin-to-skin contact affects hormone levels – and may promote parental engagement.

The link is:
https://www.eurekalert.org/pub_releases/2018…/wkh-fpi101818.php

This convoluted title and the article attached, not only supports my idea of natural selection outside the genome – specifically from mother to child transfer of good bacteria after birth – but goes further.

This supports an idea that came to me earlier today,
LOVE is selected for. NATURAL SELECTION SUPPORTS LOVE!

The more parents LOVE their children, the better chance their children will grow and have children of their own, that will survive to reproduce, and so on.

“Survival of the fittest”, should go beyond conflict to now include symbiosis: Suggestion that a major part of being the most fit is :
SURVIVAL OF THE MOST LOVING!
