SIMULATION OF NATURAL SELECTION MATERIALS Plastic or paper bag containing 100 beads of two colours additional beads as needed. AIM To prove that both allele and genotype frequencies in a population would not remain constant if natural selection occurs. Natural selection is the process whereby organisms better adapted to their environment tend to survive and produce more offspring. INTRODUCTION Natural selection‚ the differential survival and reproduction of individuals was first proposed by

STATED CLEARLY: EVOLUTION AND NATURAL SELECTION (TRANSCRIPT) What exactly is evolution? In biology‚ the theory of evolution doesn’t exactly tell us how life began on Earth‚ but tells us how life‚ once it came into existence‚ diversified into the many incredible forms we see now and in the fossil record. It also helps us make sense of the way in which modern creatures continue to adapt and change today. In biology‚ evolution can be defined as: ‘Any change in the heritable traits (those are physical

1. “I like the rain. Some people will tell you that the sun is the best‚ but they are wrong. What waits for you in the sun? Skin cancer. What waits for you in the rain? Puddles to jump in. I’ll take puddles over cancer any day.” Tell me as much as you can about this passage as an argument (especially the parts). p1. Sun will bring skin cancer. p2. Rain will bring puddles that we can jump. p3: Pain is bad‚ joy is good. If a thing causes more good things than bad things‚ then it is better. p4:

Natural selection is about slow but steady progress. Through it‚ populations constantly get better-adapted. When this process is completed for all populations‚ evolution will come to a stop. 2. According to evolutionary theory

What is the difference between artificial selection and natural selection? (Give an example for both.) The key word in these processes is selection; when we have several clearly different options to decide upon‚ we look at the option we believe serves according to our best interest and “cull” the others. Artificial selection is the process of humans selecting certain phenotypes in organisms to serve their purpose. An example of artificial selection can be observed in the phenotypic diversity of

of Man and Selection in Relation to Sex. In the former‚ he presents his theory of natural selection that results from the struggle to survive (On the Origin of Species‚ 175). In the latter‚ he explains sexual selection that results from the struggle to reproduce. According to Darwin‚ natural selection is one the basic agents of evolutionary change. At the same time‚ sexual selection is divided into the two aspects of intrasexual and intersexual selection. In essence‚ natural selection involves the

Natural and sexual selection One of the first and central mechanisms proposed by Darwin during his life was that of "natural selection." Some may refer to this as "survival of the fittest‚" whereby species that produce offspring have been successful in doing so because they have produced random individual features which have lead them to live longer and pro-create offspring with the same inheritable desired features. Not all individuals will be able to reproduce‚ therefore only the fittest will "multiply

Natural selection is the process by which individual organisms with favorable traits are more likely to survive and reproduce than those with unfavorable traits. In order for natural selection to occur there must be heritable variation for a trait and there must be differential survival and reproduction associated with that trait. (C.Stated) Heritable traits become either more or less common in population as the inherited traits in the differential reproductive success of the better adapted organisms

Here we have some highlights of how the natural selection works and some of the evolutionary forces that drive evolution: The natural selection operates in base of the difference between de reproductive successes of the individuals. The genes of the most successful individuals (the ones that reproduces more) appears more in the next generation. If an individual cannot survive it will not be able to reproduce. Because of that natural selection is NOT RANDOM and can act really quickly. (Charlat et
