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.
What is the age of the Earth in Charles Darwin's theory?
Evolutionary theory does not necessarily propose an age for the Earth. Although it does suggest that it should have existed for a minimum of a few hundred million years, to allow for the biological diversity that we find today. It is geology that establishes a timeframe for the formation of Earth. Through geological dating methods, it has been established that the Earth is approximately 4.55 billion years old.
What was principle point of the Darwin theory of evolution?
Evolution is the change in allele frequency due to non random survival and reproduction.
All organisms on Earth extant or extinct were descended from a common ancestor. This is the fact of evolution. The theory of evolution explains the mechanism of how this came to be. There are many driving forces of evolution, these include natural selection, genetic drift, recombination, mutation, migration. To keep it simple, I will explain natural selection only.
Natural selection is the differential survival of genes. Organisms make more offsprings than can survive, due to limiting factors such as food. There is variation amongst organisms, some better equipped to survive in particular environments, some less so. Thus there is a non random survival, where the better adapted individuals on average produce more offsprings than their competition, passing more of their advantageous genes to the next generation, thus evolution occurs.
How does new species arise? When a group of organisms have been isolated by a geographical barrier, or any barrier that prevents them from interbreeding, the two populations diverge and natural selection drives them to adapt to their respective environments, accumulating differences in their genomes in the form of mutations. When enough differences have accumulated, even when the two groups of organisms reunite, their genes would be too different to be able to reproduce. Thus, they became two species.
Abstract evolution is a concept that refers to the way in which biological traits in a population change over time due to natural selection, genetic drift, and other mechanisms. It embodies the idea of gradual change and adaptation in response to environmental pressures. This concept forms the foundation of modern evolutionary theory.
How did Charles Darwin explain the mechanism for evolution?
He did not and could not. Charles Darwin's "On the Origin of Species" was published in late 1859, Mendel published "Experiments in Plant Hybridization" in 1865 (6 years later) which might have led Darwin into r question in this areas, but his theories were not widely embraced until the 1900s. Nucleic Acids were not studied completely until 1950s.
Added:
The mechanism for evolution is natural selection. Charles Darwin had trouble explaining the mechanism of heredity.
