The Lost One
Yes, the article is from Wikipedia, but it has provided links to other sources, if you bothered to check the Notes and Bibliography, to other webpages, journals and books.That is a wikipedia link describing a certain prehistoric species. It says nothing about fish developing limbs.
Click on the first link and that would take you to webpage outside of Wikipedia, and that webpage would have their own bibliography, which do and can lead you to more books, journals and other webpages. And so should most of these other links, they should have their own bibliography for further readings.
I would agree that you don’t trust the Wikipedia articles, without checking their sources.
You do understand the concept of bibliography, don’t you?
