When a population undergoes strong selection what happens to it?
When a population undergoes strong selection, individuals with advantageous traits are more likely to survive and reproduce, leading to an increase in the frequency of those traits within the population. This can result in rapid evolutionary changes as the population adapts to its environment.
What genetic processes allow a species to change over time?
Genetic processes like mutation, genetic recombination through sexual reproduction, and natural selection are key factors that drive changes in a species over time. Mutations introduce new genetic variations, recombination shuffles existing genetic material, and natural selection favors traits that provide a survival or reproductive advantage in a specific environment. These processes collectively contribute to the genetic diversity and adaptation of species over generations.
What does Miller and Urey's experiment tell us about the organic compounds needed for life?
This experiment tells us that a few amino acids could be created in a sterile environment of glass test tubes over a few weeks, demonstrating that it is possible for complex organic molecules to form spontaneously under abiotic conditions.
Were there any consequences in the theory of evolution?
Yes, there have been consequences in the theory of evolution, such as shaping our understanding of the diversity of life on Earth, explaining the relationships between different species, and influencing fields like ecology, genetics, and medicine. Additionally, it has led to significant debates and challenges to certain religious beliefs.
What type of selection can create 2 new species from one population?
There are several types of selections that can do this. It includes allopatric speciation where the population is separated by physical barrios, sympatric speciation where variations occur in the population, and allopolyploid when two species merge.
What sequences depicts a hypothesized evolutionary scenario?
Which process of new species formation does this scenario describe?
The scenario most likely describes allopatric speciation, where a population is divided by a physical barrier, leading to reproductive isolation and the formation of new species due to genetic divergence over time.
Process of new species formation does this scenario describe?
This scenario describes allopatric speciation, where a population becomes geographically isolated and subsequently diverges genetically and reproductively from the original population, leading to the formation of a new species over time.
What was the first step in the origin of life?
It depends on what u believe in theres the bible and theres science.....
Scientist say that an asteroid hit the moon causing a big chunk to come off, all the space matter and that chunk started to form earth. on earth there was a bunch of volcanoes and it was very hot, water started to form in a hole then bacteria started to form, the bacteria went through Evolution creating modern day humans.....
It appears there is a typo in your question. If you meant to ask about "evolve," it refers to the process of gradual development or change over time, typically resulting in something becoming more advanced or complex. If you have a specific context in mind, please provide more details for a more accurate answer.
How does Sexual Dimorphism influence evolutionary change?
Sexual dimorphism can drive evolutionary change by creating competition between males for access to mates, leading to traits that enhance mating success. This competition can result in the evolution of exaggerated secondary sexual characteristics, such as elaborate courtship displays or physical features that attract mates. Additionally, sexually dimorphic traits may be favored by natural selection if they enhance reproductive success, contributing to the overall genetic diversity within a population.
What are the differences between Darwin's theory of evolution and conflicting theories?
It is no longer Darwin's theory, as Darwin has been dead about 130 years. There are no credible alternatives to the modern theory of evolution by natural selection. So, the differences is; the theory of evolution by natural selection is supported by myriad lines of converging evidence and explains the natural phenomenon that is evolution very well. The " conflicting theories " have no evidence supporting them and explain nothing.
How does survival of the fittest work?
Survival of the fittest, a concept in evolutionary biology, refers to the idea that individuals better adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to their offspring. Over time, this process leads to the evolution of populations with traits that enhance their survival and reproductive success in their specific environment. It is a key mechanism of natural selection proposed by Charles Darwin.
Can science explain creation and evolution?
There are two thoughts on the word creation 1. To make something from already existing materials 2. To bring into existence from nothing. As one cannot make something from nothing then the first idea must be the right one. The proper term for this is to organise and not create. The second part of your question regarding evolution is that all things evolved from some minute organism that suddenly came into existence, this is impossible. That evolution is still taking place must be considered in the light that all things are evolving. Man is taller,living longer. Girls are maturing at an earlier age. This is called The Law of Evolution. This is what we must think of when talking on this subject, the Law of Evolution
What is the true about gradulism with respect to punctuated equilibrum?
Gradualism suggests that evolution occurs slowly and steadily over time, while punctuated equilibrium proposes that species remain stable for long periods with sudden bursts of change. Punctuated equilibrium suggests that evolutionary change can happen rapidly in localized populations, leading to new species formation. Both theories offer explanations for the pace of evolution, with punctuated equilibrium emphasizing episodes of rapid change interspersed with periods of stasis.
How long does divergent evolution take to occur?
It has happened in as little as a single generation in the case of orchids. Generally speaking, groups of organisms that do not interbreed on on the borders of speciation, whereas those that cannot interbreed are considered to be separate species.
Dromedaries and llamas have been separated by more than ten million years, yet they can interbreed. Humans and chimpanzees are separated by less than six million years, yet it is doubtful our species can interbreed.
It probably depends significantly on the amount of change between groups, but I would estimate most species separated for more than a hundred thousand years would be sexually incompatible.
That they change frequency from one generation to the next and can be easily calculated, with morphological traits visible and Mendelian expression seen, by this polynomial expansion.
p2 + 2pq + q2 = 1

What is a change in genes of a population over time?
A change in the genes of a population over time is known as genetic evolution. This occurs through natural selection, genetic drift, and gene flow, leading to changes in the frequency of traits within a population. Over generations, these changes can result in the emergence of new species or adaptations.
What is the theory of evolution in skellig?
In "Skellig," the theory of evolution is not explicitly discussed. The novel focuses more on themes of hope, resilience, and the miraculous nature of transformation in the characters rather than the scientific theory of evolution.
Jean-Baptiste Lamarck proposed this idea in his theory of inheritance of acquired characteristics. He suggested that organisms could pass on traits acquired during their lifetime to their offspring, leading to evolutionary change.
What is next evolution for human?
The next evolution for humans could involve advances in technology, genetic engineering, and potentially even merging with artificial intelligence to enhance our physical and cognitive abilities. It may also involve exploring ways to extend human lifespan and improve overall health and well-being through advancements in medicine and biotechnology.
The three types of evidence that suggest organisms are related through common descent are anatomical evidence (similarities in body structures), molecular evidence (similarities in DNA sequences), and fossil evidence (transitional forms showing evolutionary changes over time).
How do genes play a role in evolution?
Evolution is, the change in allele ( different molecular form of the same gene ) frequency over time in a population of organisms. Genes are the hard heritability material that carry successful variation unto the next generation of organisms. They are also the ultimate target of natural selection in individual organisms. An organism with a gang of successful genes is reproductively successful and passes those traits on to future generations; into the populations gene pool.
What is a pattern of evolution in which two species evolve in relation to each other?
This is known as coevolution, where two or more species influence each other's evolution. It can lead to a series of reciprocal evolutionary adaptations between the species, such as predator-prey relationships or mutualistic interactions like pollination.
