You are on a remote, uninhabited island. While walking along the beach, you see "John 1800" engraved on a boulder. Do you assume that because the island is isolated and uninhabited, the marks must be the result of wind or water erosion? Of course not! You right conclude that someone made the inscription. Why? For one thing, a string of well-defined letters and numbers-even if they are in a foreign language-does not occur naturally. Second, the statement contains meaningful information, indicating an intelligent source.
CAN COMPLEX INFORMATION LIKE DNA WRITE ITSELF?

It's not uninhabited and you're at the meeting spot at the wrong time.

Very good. Where science and politics collide.

A certain type of evolution can be observed in microscopic organisms in an observable short-term timeframe. Covid would be a relevant example.

Whereby natural mutations in the virus that are resilient to vaccine(s), lead to that gene being adopted preferentially on reproduction, thus giving immunity.
Anther observable example is that the human species appears to be getting bigger over time. (look at Tudor building and ships, and see how small people were then)

As for the initial process of the first life developing, I am still inclined towards comet-seeding.

I like the evolution videos of bacteria, as its evidence is in real time and is a thing of never ending wonder.

I'm quite interested in the evolving of plastic eating bacteria because if we can get that right we can make significant strides with waste from modern living and the protection of natural environments.

Western countries definitely grew better with the gradual access to better protein diets. For a couple of generations obesity has gone from an indication of western wealth to an indication of western poverty.

When we think of life (in terms we understand) how you get to the first cell(s) is an interesting discussion but its hard to be firm on anything. The comet idea could certainly be accurate, as early solar systems are full of impacts.

We notice that life all follows forms of mathematical design with routines that run all the time. We are still very far from having an holistic understanding of nature.

That might be down to nutrition. It could also be a mixing of genes. Britons thought that the Vikings were big as I recall.
Studies have shown that generations fluctuate between being bigger and smaller.
Small island population can go dwarf or giant.

But somehow somewhere life in its basic form had to start. Ameobas or whatever started somewhere.
Even if God started us it still had a beginning with nature. Oh my head hurts.

Some people think that the universe's galaxy clusters, form into structures that resemble brain neuron networks.

Now that's enough to blow anyone's balloon that's for sure.

A timely piece on the Amazon. Did the asteroid cause the adaption of existing species, or did it contain new material ?

[Link]

"The asteroid impact that killed off the dinosaurs gave birth to our planet's tropical rainforests, a study suggests.

Researchers used fossil pollen and leaves from Colombia to investigate how the impact changed South American tropical forests.

After the 12km-wide space rock struck Earth 66 million years ago, the type of vegetation that made up these forests changed drastically.

The team has outlined its findings in the prestigious journal Science.

Co-author Dr Mónica Carvalho, from the Smithsonian Tropical Research Institution in Panama, said: "Our team examined over 50,000 fossil pollen records and more than 6,000 leaf fossils from before and after the impact."

They found that cone-bearing plants called conifers and ferns were common before the huge asteroid struck what is now the Yucatan Peninsula in Mexico." (BBC website)

Robust theories are always being "tweeked" and refined.

That is so weird but is a planet alive even if its a dead planet. Communicating with each other maybe.
