https://berthub.eu/articles/posts/amazing-dna
Bert Hubert's long-running article explains DNA biology through the lens of a computer programmer, drawing analogies between genetic code and software concepts like error correction, compression, and the halting problem. Originally written in 2001 and revised multiple times since, it became popular enough to spawn a two-hour conference presentation and an upcoming book.
https://panspermia.org/
Cosmic Ancestry is a deep-dive scientific resource exploring the theory of panspermia, arguing that life on Earth originated from space and that all evolutionary innovation depends on genetic material of cosmic origin. The site covers astrobiology, comets as delivery systems, interstellar dust, the work of Fred Hoyle and Chandra Wickramasinghe, and presents extensive evidence comparing Darwinism with the Cosmic Ancestry hypothesis.
