直到他去世时,达尔文和他的同事已经说服了大多数科学家,进化作为'''<font color="#ff8000"> 后代渐变Descent with modification</font>'''这一概念是准确无误的。他也因此被认为是伟大的科学家,因为彻底颠覆了概念。1909年6月,尽管当时很少有人同意“自然选择是主要但非排他性的后代渐变手段”这一观点,但达尔文受到了世界各地400多名官员和科学家的嘉奖,他们甚至在剑桥举行纪念仪式,以怀念他的百年诞辰和《物种起源》五十周年。大约在20世纪初,即所谓的“达尔文主义消亡”时期,科学家们提出了各种能替代自然选择的进化机制,但最终均被证明站不住脚。英国统计学家罗纳德·费舍尔Ronald Fisher在1918年至1930年的著作《'''<font color="#ff8000"> 自然选择的遗传学理论The Genetical Theory of Natural Selection </font>'''》,终于将孟德尔遗传学与自然选择结合起来。他为该理论提供了数学基础,并引起广泛的科学共识,即自然选择是进化的基本机制,从而为人类遗传学和现代进化综合奠定了基础。霍尔丹Haldane和塞沃尔·赖特Sewall Wright为现代辩论和对该理论的完善设定了参考框架。
