it's not the same as evolution because the genes would change within the individual during their lifetime
Lamarckism.Lamarckism (or Lamarckian inheritance) is the idea that an organism can pass on characteristics that it has acquired during its lifetime to its offspring (also known as heritability of acquired characteristics or soft inheritance). It is named after the French biologist Jean-Baptiste Lamarck (1744–1829), who incorporated the action of soft inheritance into his evolutionary theories as a supplement to his concept of an inherent progressive tendency driving organisms continuously towards greater complexity, in parallel but separate lineages with no extinction. Lamarck did not originate the idea of soft inheritance, which proposes that individual efforts during the lifetime of the organisms were the main mechanism driving species to adaptation, as they supposedly would acquire adaptive changes and pass them on to offspring.
When Charles Darwin published his theory of evolution by natural selection in On the Origin of Species (1859), he continued to give credence to what he called "use and disuse inheritance," but rejected other aspects of Lamarck's theories. Later, Mendelian genetics supplanted the notion of inheritance of acquired traits, eventually leading to the development of the modern evolutionary synthesis, and the general abandonment of the Lamarckian theory of evolution in biology. Despite this abandonment, interest in Lamarckism has continued.
ya i am thinking that might be possible and there is no reason to abandon interest all together
there is nothing truly far-fetched about altering the genetic code through experience
seems like a fashionable area of potential study too since most people think evolution by natural selection is too slow for our time anyway
then again it might not be possible...it may be considered redundant given human's capacity for technological advancement which the sort of more immediate adaptation this evolution on an individual level would afford...but it could still be beneficial
maybe....natural selection will select individuals now who have this potential to evolve within their lifetime
that's certainty possible
a genetic mutation that allows genes to change
maybe it can even be created in the lab...instead of waiting for natural selection to come up with something
but maybe natural selection has already determined that humans should not do this...and so the thought has not occured to them
