In an “Ancient Greek” technological world a magical plague causes the extinction of all animals larger than a chicken, or say 5lbs/2kg. Some Humans and small animals (cats and dogs) survive this by virtue of being deep underground.

1000 years passes.

  • Would many species of flora end up dying off?
  • Would the dominant species end up being hares, boars and hawks?
  • How would the lack of draft animals effect society?
  • How would the lack of animals effect warfare?
  • How much larger can existing animals be bred over hundreds of years?

  • What sort of unknowns have I not considered?

  • $\begingroup$ Boars and hawks are usually bigger than that... $\endgroup$ – Spencer Jan 27 at 13:35
  • $\begingroup$ I was thinking baby pygmies would survive.en.m.wikipedia.org/wiki/Pygmy_hog Also, hawks are about 1kg so they survive. $\endgroup$ – Hippeus_Lancer Jan 27 at 13:38
  • $\begingroup$ Way to broad, each question by themselves are pushing too broad. $\endgroup$ – John Jan 27 at 17:27
  • $\begingroup$ SE's model is one-specific-question/one-best-answer. I count 7. Additionally, the "too broad" rules are that a question that would require a book to answer all of the considered conditions is also too broad. Questions #1, #2, #4, #5, and #7, even if asked individually, are too broad. Questions #3 and #6 are primarily opinion-based unless criteria is provided to explain how you will judge a best answer. Please consider asking questions in our question sandbox to perfect them before posting them on the main site. $\endgroup$ – JBH Jan 27 at 18:14
