History of the Earth・2 minutes read
Darwin grapples with the sudden appearance of complex animal life in the fossil record despite his theory of gradual evolution, sparking ongoing debate on the Cambrian explosion. Various theories proposed to explain the sudden emergence of complex life forms remain elusive, prompting further investigation into potential triggers and factors influencing this biological revolution.
Insights
- The Cambrian explosion, occurring around 540 million years ago, remains a scientific mystery with various proposed theories, such as incomplete fossil records, missing links, and the evolution of shells, attempting to explain the abrupt appearance of complex life forms.
- The rise of animal life during the Cambrian era was influenced by factors like increased oxygen levels due to tectonic events, leading to biological diversification, which parallels the sudden emergence of AI technology, showcasing fully formed entities after a period of stagnation.
