A random mutation is introduced into the genome, whether by genetic mistake or otherwise. If it makes any difference to the behavior of the bacterium is unlikely, but if it is beneficial it will have an advantage over competitors. Which makes it more likely for it to reproduce and more likely to pass on the beneficial mutation. This process repeats and success! The bacterium has evolved.
What else can I help you with?
What did darwin call the process by which evolution takes place?
The book, On The Origin Of Species, " suggested " that organisms evolve through the process of natural selection. The nonrandom survival and reproductive success of randomly varying organisms
Is it true that through natural selection harmful variations gradually accumulate in a species?
yes
What principle states that living things change gradually over time through natural selection?
The theory of evolution by natural selection.
How do things change over time?
They adapt and evolve through the process of natural selection and learned behaviours.
What process did Darwin's book suggest that organisms evolve through?
These three ideas seem to run together, so it's important that you are able to distinguish among them. The theory that organisms change over time is evolution. The mechanism by which organisms evolve is natural selection. Survival of the fittest explains how natural selection works.Answer = Natural SelectionThe process of natural selection, of course.
How can you use superbugs as an example of natural selection?
Superbugs that develop resistance to antibiotics through genetic mutations provide a clear example of natural selection in action. When exposed to antibiotics, the individuals with mutations that confer resistance are more likely to survive and reproduce, passing on their resistant genes to the next generation. Over time, this can lead to a population of bacteria that is predominantly resistant to antibiotics.
Did penguins go through natural selection?
Yes, penguins, like all animals, have gone through natural selection. Scientific evidence supports this notion.
Are Antibiotic resistance evolved through the process of natural selection acting upon random mutation?
Yes, antibiotic resistance typically arises through a combination of random mutations in bacteria's genetic material and natural selection favoring those bacteria that have mutations conferring resistance to antibiotics. Over time, these resistant bacteria survive and multiply, leading to the emergence of antibiotic-resistant strains.
Explain why the evolution of resistance to antibiotics in bacteria is an example of directional natural selection?
All bacteria, as are all organisms, are variants and some of these variants are resistant to antibiotics. So, a population of bacteria, in their immediate environment, are subjected to an antibiotic and most succumb. So, the resistant, survive the onslaught ( are naturally selected ) and reproduce progeny that are also resistant to the antibiotic. So, allele frequency shifts and evolution occurs die to the adaptive change conferred on the progeny population by natural selection.
Who helped develop the theory of evolution?
The developers of the theory of evolution by natural selection were Charles Robert Darwin and Alfred Russel Wallace.
Did natural selection give rise to our ability to drive automobiles?
No, our ability to drive automobiles is not a trait that has evolved through natural selection. Driving is a learned skill and is not influenced by genetic traits that are subject to natural selection.
How do adaptations arise in a species?
Through natural selection and evolution
How would you use evolution natural selection adaptation and fitness in a sentence?
An important mechanism in evolution is natural selection, which allows populations to develop adaptations to changing circumstances based on the fitness landscape of the environment. Nah, still doesn't work. I'm no good at long sentences.
How is resistance to antibiotics shared from one bacteria to another?
Bacteria develop resistance to antibiotics through the process of natural selection. The antibiotic will kill most of the population of bacteria but not all because some of them already have the resistance. Also if the antibiotic is not utilized correctly ( according to a physicians instructions ) some of the more hardy individuals of the bacteria population will live. These bacteria breed and produce offspring that are also more resistant to antibiotics. Generations of bacteria happen much more rapidly than with people so the ability of bacteria to adapt to new environments is much more robust with respect to time.
What is the best definition for the concept of evolution?
Evolution is the process by which different species of organisms develop and change over time through genetic variation and natural selection, leading to the emergence of new species.
Which scientist is known for the theory of evolution through natural selection?
Charles Darwin is known for the theory of evolution through natural selection. He proposed that all species of life have descended over time from common ancestors, and that the process of natural selection is the mechanism through which this evolution occurs.
Why does natural selection not directly affect genes?
Natural selection acts on the way organisms interact with one another and with their environment. The genes of organisms are not usually themselves involved in this interaction: they direct it through intermediaries such as proteins. So natural selection must work through these intermediaries to affect genes.
