This means that, when a bacteria cell splits, both halves of the split are identical -- they contain exactly the same DNA. The offspring is a clone of the parent. As explained in How Human Reproduction Works, higher organisms like plants, insects and animals reproduce sexually, and this process makes the actions of ...

Natural selection allows only the “fittest” to survive … WebLiving things have evolved into three large clusters of closely related organisms, called "domains": Archaea, Bacteria, and Eukaryota. Archaea and Bacteria are small, relatively simple cells surrounded by a membrane and a cell wall, with a circular strand of DNA containing their genes. They are called prokaryotes.

That said, it doesn’t help us scientifically explain how and why that single-celled organism is conscious. According to the prevalent neuroscientific view of consciousness, single-celled organisms have no neurons to do any “thinking”, per se.
Webconvergent evolution, bioluminescence is estimated to have evolved independently at least forty times [1–3]. This has led to the chemistries of bioluminescent reactions being as diverse and unrelated as the organisms that produce them [2–4]. Dinoflagellates are the main eukaryotic protists that are capable of producing light [1,5]. Within this
