A new study has found that evolution is not as unpredictable as previously thought, which could allow scientists to explore which genes could be useful to tackle real-world issues such as antibiotic resistance, disease, and climate change.
The study, which is published in the Proceedings of the National Academy of Sciences (PNAS), challenges the long-standing belief about the unpredictability of evolution and has found that the evolutionary trajectory of a genome may be influenced by its evolutionary history, rather than determined by numerous factors and historical accidents.
Not really, no. In a sense, never has been. “Survival of the fittest” was a poor formula (I remember reading that Darwin was not fond of it at first and used it somewhat reluctantly but I can’t remember where), and a very bad summary of the theory of evolution. To start with because the important thing is differential reproduction (with modifications) between individuals, but not survival per se. But also because natural selection is just a part of the modern theory and many others aspects have been added since then (mutations, drift, phenotypic plasticity, environmental inheritance, etc).
