These days even most creationists acknowledge that microevolution has been upheld by tests in the laboratory ( as in studies of cells , plants and fruit flies ) and in the field ( as in grant ' s studies of evolving beak shapes among gal pagos finches ) 现在甚至大多数创造论者都承认，微演化经得起实验室研究的考验（例如以细胞、植物、果蝇完成的实验） ，以及田野测验（像是葛兰特在加拉巴哥群岛上研究雀鸟喙嘴形状的演化） 。
