Rationale “Humans have stopped evolving and are no longer subject to natural selection.”(O’Rourke, 2020) Is an extremely broad claim with no evidence to support it, evolution is “the process by which new species or populations of living things develop from pre-existing forms through successive generations”(Gould, 2020) Whereas “natural selection is the process of which a selective agent acts on a population and results in certain organisms having greater chances of survival.”(O’Rourke, 2020) Producing stronger second-generation offspring. Through these understandings it...

An Overview Selection is frequency dependent when the fitness of a phenotype, genotype, or gene (or species) varies with its relative abundance in the population (or community) and hence can be detected only when measured at two or more frequencies. In “negative frequency-dependent selection,” fitness decreases with frequency and thus rare genotypes or species could be maintained at a stable equilibrium. As a form of balancing selection, this mechanism could be one explanation for the persistence of higher than expected...

Introduction Natural Selection has a great effect on species in different environments. Different species can inherit mutations, some may be good, and some may be bad for the individual(McGraw-Hill Ryerson. 2010). It is also the reason for evolution(Grabianowski, 2018). Natural Selection is the leading factor in deciding which species will live and reproduce, and which ones will die out(Brain, 2019). This lab will simulate the effects of Natural Selection on a population of bead bugs. The dependent variable is the...

Introduction (200 words) Natural selection, a key concept in evolutionary biology, profoundly shapes the diversity of life. This principle, first elucidated by Charles Darwin, explains how species evolve and adapt through generations. It is the process by which traits that enhance survival and reproduction become more prevalent within a population, leading to the gradual evolution of species. This dynamic reflects the ongoing adaptation of life to various environmental challenges, a testament to the resilience and ingenuity inherent in nature. The...
