<p> </p>
<p> </p>
<p>Abstract</p> <p> To understand conceptDarwinism is a theory of biological evolution developed by English naturalist Charles Darwin, stating that all species of organisms arise and develop through the natural selection of small, inhereted variations that increase the individual's ability to compete, survive and reproduce. Pangenesis, which is a theory of heredity hypothesized by Darwin, cause was supporting Darwinism as it explained heredity of variations. I found that Gregor Mendel's experiments and consequenceother evidences attacked Darwinism by refuting pangenesis. Hence, Darwinism supported by pangenesis is not perfect to explain the biological evolution.</p> <p> </p> <p>Introduction</p> <p> Since 1832, when Charles Darwin arrived at Galapagos islands where various traits and species exists, the concept of evolution has been considered as one ofthe most powerful evolution is very important tool to research on a number explain the variety and origin oflife. But, as crucial evidences and theories such as biology field. Since Mendel's law of inheritance emerged, the time theory of Darwin evolution has been changed gradually, who suggest which makes the first model of evolutionobsolete. Through that way, there we are many controversies around evolution including conflict between religions and evolutionists, and different views ignorant about what Darwin's original theory tried to explain the way the evolution occurssay. In Now, in this short essay, we will want to focus more about Darwin's first model and criticize it on many biological terms.</p> <p> </p> <p><strong>Darwin'sExplanation : Gemmule and Pangenesis</strong></p> <p> Observing taxidermied birds' traits, Darwin found that there are correlation between their first model throughspecific traits and their habitats. He had inspiration from Hippocrates's view on the topic, which made Darwin establish and publish critical his view with "pangenesis". Pangenesis was Darwin's model to explain the mechanism for heredity and evolution using imagined particles named as gemmule which appeared in his book 'The Variation of Animals and Plants under Domestication', pubilshed in 1868, nine years after pubilcation of his famous book 'On the Origin of Species'. </p> <p> Gemmules were assumed to be spread within all parts of body and carried in the bloodstream to the reproductive organs where they accumulated in germ line cells. Gemmules were also able to be changed easily affected by surroundings or natural pressures. It seemed to explain well-known therories how acquired traits are inhereted, yet there were lots of problems preventing it accepted.</p> <p><strong>Defects on Pangenesis</strong></p> <p>1. Pangenesis can not explain Mendel's Cross expriments.</p> <p> Gregor Mendel's study totally defeated Darwin's mechanism. Mendel proved that heredity has at least one certain discrete unit to express one trait. Unfortunately gemmule couldn't be that unit as it was continuous concept anddid not have method to evidences explain law of dominance, segregation and briefly evaluateindependent assortment..</p> <p>2. Acquired traits are not inherited.</p> <p> Lamarckism was very similar to Darwinism in that both were trying to explain that evolution occured within relatively short time. Both are not true because acquired traits are not inherited (but epigenome), which cannot affect phynotypes. </p> <p>3. Pangenesis can not explain asexual propagation</p> <p> about his theory with basic biological lens including developmentAccording to the pangenesis, gemmule should be inhereted by sexual propagation. However, there are many asexual reproductions such as binary fission, growthbudding, reproduction and inheritance of lifevegetative propagation.</p>
