A better intro to MartinV is
Mimicry and neodarwinism (which he started and is now closed) and
Mimicry: Please help me understand how. Watch for head spinning circular arguments. That repeat.
My first impression is that it is fairly normal for ground dwelling egg laying animals to cover the eggs with debris while they go to feed, as hidden eggs are less likely to be found by predators than unhidden ones.
That's all it takes to start a system of covering with selection for those that are better at hiding/burying.
I don't have any problem with this behavior being re-evolved in many different applications.
Enjoy.
