Question

Over centuries cockroaches have become smaller and flatter, making it easier for them to hide and find their way into home cabinets and pantries. What does this demonstrate?

(Can I get one paragraph with explain)

Answer 1

survival of the fittest, they've adapted to their environments to be able to reproduce they've also been able to change. When a cockroach that was born with the inability to fit through small cracks to find food theyd probably end up dying meaninf they couldn't reproduce their specific species, whilst those who could would survive and in end would be able to reproduce
