Exactly, even from the beginning complexity (or information) arises naturally when just two atoms join togther to form molecules, remember the Universe is "fine tuned" to do so. We find the earth starts out originally with an entire array of new formed elements, complex molecules plus vast amounts water in liquid, gas & solid states. Its elementary to assume that further chemical complexity will arise from there, earth was not a frozen gas giant nor a hellish planet like Mercury too close to its parent star.
Change & emerging chemical complexity is just built in, the Earth was already rich in the beginning with the potential for the emergence of molecules of higher and higher information content or complexity. This would apply to teeming life later as well.
"But recently some scientists and philosophers have suggested that complexity
can arise through other routes. Some argue that life has a built-in tendency to
become more complex over time. Others maintain that as random mutations arise,
complexity emerges as a side effect, even without natural selection to help it
along. Complexity, they say, is not purely the result of millions of years of
fine-tuning through natural selection—the process that Richard Dawkins famously
dubbed “the blind watchmaker.” To some extent, it just happens.? |
