One-celled Life Possessed Tools for Going Multicellular

One of the hardest things for Eugenicists to accept is that there is almost never a single gene for this or that trait. We share more genes with other species than not. Truth is, species, and individual differences within species, arise mostly from gene-regulation, not our DNA. And gene-regulation is often an adaptive response to environmental change.

In this light, one of the mysteries of the origins of complex and multi-cellular organisms is now solved. Turns out a single-celled amoeba called “Capsaspora owczarzaki” had the tools for going multicellular all along - and evolution is mostly about recycling old genes, with proteins regulating those genes.


One-celled life possessed tools for going multicellular

Scaling up from one cell to many may have been a small step rather than a giant leap for early life on Earth. …

“Animals are regarded as this very special branch, as in, there had to be so many innovations to be an animal,” says David Booth, a biologist at the University of California, Berkeley who wasn’t part of the study. But this research shows “a lot of the machinery was there millions of years before animals evolved.”

...That parallels what’s seen in animals: Proteins in different organs within the same animal show similar modification differences.

The researchers also found changes in the molecules that control the protein modification process. ...

the earliest animals were probably “recycling mechanisms that were already present before,” says study coauthor Iñaki Ruiz-Trillo, a biologist at the Institute for Evolutionary Biology in Barcelona.

...the perceived chasm between a simple single-celled existence and a complex multicellular one might not have required a flying leap to cross. “This gap,” Sabidó says, “maybe isn’t such a gap.”

This complex interdependent living system we have on Earth that works together - like how bacteria and plants created an atmosphere so that other beings can thrive and exist on this planet shielded from the outside elements.. How plants bacteria and trees provide food and oxygen for other living beings to work as a working system..

Is it coincidental that all these things worked together so well?

Or was it designed/programmed and understood from the very beginning? ..from the first single celled organism that came upon / that came to be, on Earth.

Evolution explains this all well enough.

Yes. Our evolutionary systems are truly elegant.

Not really.

Whether all the parts working together was planned from the start, or whether it was "coincidental" that it did, is not clear-cut.

Yes, really.

Please at least read a Wikipedia page or two on the topic first. Your argument not only has no scientific basis but, had you started with even a cursory education on the topic, would understand how a) the design argument is bunk and b) how evolution literally explains the very confusion on the topic of coincidence you exhibit.

Right now you're saying something akin to "if gravity is real, why don't things fall upwards?". Such ponderings say more about your understanding of the topic than the topic itself.
