The relation of these observations to Jordan's especes affines is obvious.
Therefore I will here quote a few examples of both, from his paper Du Developpement des Especes Sociales[24].
Plus on suppose l'agriculture ancienne et remontant a une epoque d'ignorance, plus il est probable que les cultivateurs avaient choisi des especes offrant a l'origine meme un avantage incontestable.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "especes" in a variety of sentences. We hope that you will now be able to make sentences using this word.
