Darwinian evolution includes Lamarckian inheritance of acquired characters

Adaptation under Changing Environments with Various Rates of Inheritance of Acquired Characters: Comparison between Darwinian and Lamarckian Evolution

Evolving Learnable Neutral Networks Under Changing Environments with Various Rates of Inheritance of Acquired Characters: Comparison Between Darwinian and Lamarckian Evolution

The processes of adaptation in natural organisms consist of two complementary phases: learning, occurring within each individual's lifetime, and evolution, occurring over successive generations of the population. In this article, we study the relationship between learning and evolution in a simple abstract model, where neural networks capable of learning are evolved using genetic algorithms (GA...

The origin of acquired immune deficiency syndrome: Darwinian or Lamarckian?

The subtypes of human immunodeficiency virus type 1 (HIV-1) group M exhibit a remarkable similarity in their between-subtype distances, which we refer to as high synchrony. The shape of the phylogenetic tree of these subtypes is referred to as a sunburst to distinguish it from a simple star phylogeny. Neither a sunburst pattern nor a comparable degree of symmetry is seen in a natural process su...

Lamarck, evolution, and the inheritance of acquired characters.

Scientists are not always remembered for the ideas they cherished most. In the case of the French biologist Jean-Baptiste Lamarck, his name since the end of the nineteenth century has been tightly linked to the idea of the inheritance of acquired characters. This was indeed an idea that he endorsed, but he did not claim it as his own nor did he give it much thought. He took pride instead in adv...

Lamarckian and Darwinian Theories

What is it that makes natural evolution so successful at finding solutions to real-world problems? If this question can be understood and answered we will be in possession of a powerful new tool for overcoming many of the difficulties now being faced by the more mathematical approaches to communication problems. Evolution will not tolerate Lamarckian control. Indeed unfettered diversity is the ...
