2. Yes if we consider the beads to be living organisms then we can say that evolution did occur because after some generations the frequencies of the green and white beads changed leading to more in white beads and less in green beads. . Now the factor which is in motion in this case scenario is Natural Selection. Those individuals which survive longer and reproduce at a higher rate profucing more number of offsprings are favoured by nature in comparison to those who are less adapted to a particular environment. So the fitter organisms (whose reproductive rate is higher) contribute higher percentage of genes in the gene pool of next generation while less fitter ones produce fewer offsprings. If this situation continues for several generations like in the case mentioned above then the fitter genes will accumulate more in the total gene pool of the population. Thus those individuals which are favoured by natural selection in a particular situation will ultimately reproduce more (like white beads increasing their frequency in the population) and becomes the normal state of being by passing on the favourable characters and causing the species in question to evolve. 3. Assuming the table cloth was green in colour, the green beads would easily camouflage with the background making it a bit difficult for the predator to chose them over the white beads which are clearly visible in a green background. This would alter the situation completely since natural selection would then favour the green beads which would durvive thd predator and reproduce at a higher rste increasing the frequency of the green beads. White bead on the other hand would be easily preyed upon by the predator because of their easy visibility thus decreasing their number, reproductive rate and hence gen frequencies. 4. According to this situation bead colour is not an adaptation in the initial stages. But when the predation will contunue for a longer period of time, the animals might adapt for a favourable character which might prevent predation making them fitter for that particular environment. But in the case given since the predation is random, color should not influence the situation. Solution 2.
