Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.

Scientists have discovered that people carry a staggering variety of bacteria on their hands. They found a total of 4,742 different species. Individual test subjects averaged 150 different types, with women averaging more types of bacteria than men. Scientists are not sure why but have offered several possible explanations. The difference may have something to do with acid on the skin. A man's skin generally has more acid than a woman's skin does, and bacteria do not thrive as well in more acidic environments. Another cause could be the differences in sweat and oil produced. Makeup use could also make a difference, as could skin thickness. Do It!

Question -Esther is completing her PhD project in bacterial distribution in mangroves and theirbiochemical characteristics. She manages to isolate and identify around 80 differentbacterial species from the various mangrove sites. She preserves the isolates by growingthem on a tryptic soy agar supplemented with sea salt and re-streaks them every week. After8 months she notices that some of the isolates have changed their genetic sequence whencompared to the initially identified sequence. Using a diagram explain what could havehappened to the isolates when she re-streaked them repeatedly and recommend a solutionto prevent this from occurring in the future and give explanation why it is moreadvantageous.
"On the rapidity of antibiotic resistance evolution facilitated by a concentration gradient" ABSTRACT The rapid emergence of bacterial strains resistant to multiple antibiotics is posing a growing public health risk. The mechanisms underlying the rapid evolution of drug resistance are, however, poorly understood. The heterogeneity of the environments in which bacteria encounter antibiotic drugs could play an important role. E.g., in the highly compartmentalized human body, drug levels can vary substantially between different organs and tissues. It has been proposed that this could facilitate the selection of resistance mutants, and recent experiments support this. To study the role of spatial heterogeneity in the evolution of drug resistance, we present a quantitative model describing an environment subdivided into relatively isolated compartments with various antibiotic concentrations, in which bacteria evolve under the stochastic processes of proliferation, migration, mutation and…
