Not answered the poll because it's not quite black and white. It's the best explanation there is but it may be modified if new evidence comes to light.
Ok you edited the poll, i can answer now
You’re right.
Since Darwin’s and Wallace’s time, Evolution have been modified multiple times, to allow for alternative mechanisms to the original mechanism, Natural Selection, like
- Mutations,
- Genetic Drift,
- Gene Flow,
- Genetic Hitchhiking
These later aren’t meant to replace Darwin’s Natural Selection, but to explain and demonstrate there are more than one ways for evolution to occur.
Natural Selection itself have also modified, to correct any errors Darwin and Wallace have made, as well as expanding and improving Natural Selection, because of other fields in biology, including
- replacing Darwin’s genetics (eg pangenesis) with Mendel’s genetics,
- molecular biology,
- biochemistry,
- DNA testing,
- taxonomy have been updated and improved (eg taxonomic “clade”),
- Biostraigraphy, and paleontology, as well as multiple dating methods have all been discovered, updated or improved,
- etc
Abiogenesis is currently a working hypothesis, that may well be a new and separate field, added to already very broad life sciences.
Evolution can still be updated in the future, all depending on if new evidence are found.
