Hmm.... Egg laying mammals??
May I ask what makes them mammals if they lay eggs?? Your posts are always really educative.. Never knew this at all...
Two things define them specifically I think: Nurture with milk (the egg laying monotremes still do this in a different way) and hair/fur. There are bound to be exceptions to all of these things though, probably! Generally you should tick a few boxes to be classified
Yeah Yeah... You should tick a few boxes to be classified as a member of a group and only the egg laying factor is not enough to disqualify them from being classified as mammals...
Thanks for the clarification...
