ABSTRACT:
A method of and means for demonstrating organic evolution, particularly as it involves the mechanism of natural selection. Background panels of multicolor and intricate design or pattern are used to provide simulated natural environments, and thin chips of different colors and shades -- and, in some instances, of different sizes and shapes -- are used to provide simulated animals or plants to be placed on the background panels. A population of a predetermined number of chips of a predetermined mixture of colors -- say, for instance, an equal number of from ten to twenty different colors -- is selected. The chips constituting the selected population are then spread in a single layer more or less uniformly on the surface of the background panel, and preferably in spaced relation, so that each chip is in plain view and is more or less detectible -- depending upon the color contrast existing between each chip, respectively, and the associated area of the background panel. Humans, for whom the demonstration is to be conducted, act as predators and remove from the panels a predetermined portion of the chips -- say, for instance, seventy-five percent of the total population placed on the panel. The surviving chips are then counted and noted for color, and each is reproduced in equal amount so as, for instance, to restore the original population. Reproduction is carried out by mating surviving chips and providing additional chips as simulated offspring, as are dictated by genetic demands, indicated on specially formed chips and the use of a chance device such as a specially constructed die or the like. Various aspects of natural selection may be demonstrated by this invention, including reproduction by monohybrid crosses, dihybrid crosses, and trihybrid crosses. The removal of chips as by predators, followed by reproduction for restoring the population, may be repeated any desired number of times.
