The (almost) eternal debate on what came first has persisted through decades.
Countless evenings have been spent around a table, with a wine glass (or plenty more), with people throwing arguments against or in favour of one of the answers.
Despite all thoughts, in reality, the answer is relatively simple.
The first animals to lay eggs were the dinosaurs.
𝐒𝐨 𝐭𝐡𝐞 𝐞𝐠𝐠 𝐜𝐚𝐦𝐞 𝐟𝐢𝐫𝐬𝐭!
A discovery made in 1990 in North America showed a nest of eggs from a carnivore dinosaur called “Maniraptoran”.
This dinosaur is believed to be the animal from which birds came to develop into new species.
Some suggest the new question: What came first, the dinosaur or the egg?
But we will leave that one for another time…
