Evolutionary Theory Lamarck was not recognized by contemporaries. The evidence for species variability was not convincing enough. Given the decisive role in evolution to the direct influence of the external environment, the exercise and non-exercise of organs, and the inheritance of acquired attributes, Lamarck could not explain the occurrence of a number of adaptations. So, the color of the shell of bird eggs is clearly adaptive, but explain this fact from the standpoint of the theory of Lamarck is impossible.
