He insisted on common descent, which he probably derived from Lamarck. In Darwin's Historical Sketch there is mis statement concerning Lamarck: 'In these works he upholds the doctrine that all species, including man, are descended from other species'; and further: 'with respect to the means of modification he attributed something to the direct action of the physical conditions of life, something to the crossing of already existing forms, and much to use and disuse, that is to the effect ...Environmental Ethics - Volume 3 - Page 76

Ruse finally renders Lamarck as postulating a series of linear progressions lacking any common origin (linear descent) and cautions us not to "confuse" Lamarck's portrayal with Darwin's "superficially similar" one (common descent). Properly, however, Lamarck's views would generate a series of branching systems (multiple descent), perhaps with moderately divergent results. All considered, Ruse underestimates Lamarck. Cuvier authored the principal criticisms of Lamarck ...Darwinism defended: a guide to the evolution controversies - Page 8

'Darwin's second Lamarckian concept was the postulate that the process of evolution is gradual and continuous; it does not consist of discontinuous saltations, or sudden changes. 'Darwin's two other main postulates were essentially new concepts. One was the postulate of common descent. For Lamarck each organism or group of organisms represented an independent evolutionary line, having had a beginning in spontaneous generation and having constantly striven toward ...Exobiology: matter, energy, and information in the origin and ...

When in 1793 Lamarck (1744-1829) was appointed as Professor of the inferior animals in France, which he renamed in a less uncomplimentary fashion as the invertebrates, he came up with new and valid reasons for believing in evolution and common descent, but then spoiled his case by endowing all animals with a power to interact with the environment and acquire ever greater complexity or perfection. Such a 'soft' inheritance of acquired characters has certainly to be rejected, ...Evolution - Page 49

Lamarck accepted a chain of being with irregularities. He thought that the satisfaction of needs ... One way to make Lamarck's theory more plausible is to argue that only his second mechanism involves needs, habits, and inner consciousness. The first simply involves the body's fluids ...

The establishment of order in descent and ontogeny paved the way for the discovery of order in heredity Chaos reigned in the relationships between the different organisms until Lamarck in his Philosophie Zoologique (1809) postulated that they were correlated by common descent and that their successive development progressed from the simplest to the more complex organisms. This was the first formulation of the theory of evolution. It rejected the disordered view of creation ...Origins and Species: A Study of the Historical Sources of Darwinism ...

case for the common descent of allied species. Any account of the origins of Darwinism must bring out not merely the sources of the conceptual weapons deployed, but, equally, the sources of Darwinian conceptual strategy. Darwin's first and second transmutation notebooks show that he read with the greatest care Lyell's account of Lamarck's doctrines. When we look more closely at the early pages of the first notebook, we see Darwin endorsing many Lamarckian proposals. By the ...
