The answer, of course, is that the laws of biology are nearly impossible to test, and scientists hate that. We can launch probes to test theories of gravity and space-time. We can put rocks in pressure cookers and split atoms in classrooms. But how does one test a process as lengthy and multifaceted as evolution? There are labs today that struggle to find the funding to keep a project running for three standards—imagine the funding needed to run a project for millennia!
