Why does Meiosis is said to be the key process in the rate of evolution via natural selection?
1. Why does Meiosis is said to be the key process in the rate of evolution via natural selection?
Answer:
Meiosis reduces a cell's chromosome number by half, while also creating new allele combinations distributed across daughter cells through segregation and recombination. This genetic reshuffling reduces genetic associations within and between loci and is thought to be the basis of the success of sexual reproduction.Explanation:
Mark Brianlist2. Darwin created and proposed mechanisms of evolution. Summarize the key points of his theory of evolution. In your own words, briefly explain how natural selection works.
Answer:
The Theory of Evolution by natural selection was first formulated in Charles Darwin's book "On the Origin of Species" published in 1859. In his book, Darwin describes how organisms evolve over generations through the inheritance of physical or behavioral traits, as National Geographic explains. The theory starts with the premise that within a population, there is variation in traits, such as beak shape in one of the Galapagos finches Darwin studied.Explanation:

4. who developed the theory of evolution by natural selection
Answer:
Charles DarwinThe theory of evolution is a shortened form of the term “theory of evolution by natural selection,” which was proposed by Charles Darwin and Alfred Russel Wallace in the nineteenth century.5. Explain evolution by natural selection.
Answer:
Evolution by natural selection is Charles Darwin's theory. It explains that species like giraffe have varying necks (small and long necks) he said that nature have favored those who have long necks because they could reach food while giraffes with small neck died because they can't reach for food.
6. what is evolution? natural selection?
Answer:
In the theory of natural selection, organisms produce more offspring than are able to survive in their environment. Those that are better physically equipped to survive, grow to maturity, and reproduce. Those that are lacking in such fitness, on the other hand, either do not reach an age when they can reproduce or produce fewer offspring than their counterparts. Natural selection is sometimes summed up as “survival of the fittest” because the “fittest” organisms—those most suited to their environment—are the ones that reproduce most successfully, and are most likely to pass on their traits to the next generation.
This means that if an environment changes, the traits that enhance survival in that environment will also gradually change, or evolve. Natural selection was such a powerful idea in explaining the evolution of life that it became established as a scientific theory. Biologists have since observed numerous examples of natural selection influencing evolution. Today, it is known to be just one of several mechanisms by which life evolves. For example, a phenomenon known as genetic drift can also cause species to evolve. In genetic drift, some organisms—purely by chance—produce more offspring than would be expected. Those organisms are not necessarily the fittest of their species, but it is their genes that get passed on to the next generation.

10. How does natural selection lead to evolution?
Answer:
Natural selection is a process where organisms that are better adapted to an environment will survive and reproduce. This means that the advantageous alleles of this variant organism are passed on to offspring. Over many generations, the process of natural selection leads to evolution occurring, through which populations of living organisms adapt and change. Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth

Answer:
Evolution is a gradual change in the inherited traits of a population over many generations. Natural selection is a mechanism where the members of a population best suited to their environment have the best chance of surviving to pass on their genes.
14. Theory of evolution by natural selection
Answer:
Introduction to evolution
Explanation:
Evolution is the process of change in all forms of life over generations, and evolutionary biology is the study of how evolution occurs. Biological populations evolve through genetic changes that correspond to changes in the organisms' observable traits.

21. Theory of evolution by natural selection by charles darwin
Answer:
Darwin and a scientific contemporary of his, Alfred Russel Wallace, proposed that evolution occurs because of a phenomenon called natural selection. In the theory of natural selection, organisms produce more offspring than are able to survive in their environment.
22. how does natural selection contributes to evolution?
Answer:
Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

26. Natural selection involves the evolution of individuals.
The answer is:
False27. 1. Discuss the Theory of Evolution.2. Explain why evolution by natural selection is one of the best substantiatedtheories in the history of science.3. Describe the five parts of Darwin's Theory of Natural Selection on howevolution happens in nature.
Answer:
1,The Theory of Evolution was an explanation for why that observed effect was happening.
A lot has happened since Darwin’s time in the 1800’s etc, and the genetic aspect is now the main concept to understand.
So, basically, all that happens in evolution is that genes are passed on, or, they are not.
The reason they get passed on is typically because, for whatever reasons, the genes did not PREVENT survival and allowed successful breeding/reproduction.
If your genes are such that you don’t get to reproduce, your genes are not passed on.
Even siblings are a little different from each other, and, one might pass on genes, and, one might not…so, the offspring have the genes that were from the sibling that got to reproduce.
So, the offspring tend to be more like their parents.
Taller parents tend to have taller kids, etc…so, if the genes are ‘working” and get to be passed on…whatever traits the parents had, are being bred for.
In nature, what makes the genes ‘work” is if they can survive predation, starvation, being attractive enough to mates, being fertile, caring for the young, resistance to disease or parasites, etc, tolerance of heat or cold, camouflage, size, etc.
So, “natural selection” weeds out the one’s that didn’t work…leaving the ones that DID work, to pass on THEIR genes, and so forth.
2,Evolution by natural selection is one of the best substantiated theories in the history of science, supported by evidence from a wide variety of scientific disciplines, including paleontology, geology, genetics and developmental biology.
3,Natural selection is a simple mechanism that causes populations of living things to change over time. In fact, it is so simple that it can be broken down into five basic steps, abbreviated here as VISTA: Variation, Inheritance, Selection, Time and Adaptation.
28. Evolution and natural selection been diagram
Evolution and natural selection have been diagram
Charles Darwin was a British biologist who postulated the natural selection hypothesis of biological evolution.
"Descent with modification," as Darwin defined it, is the theory that species change over time, give rise to new species, and share a common ancestor.
Natural selection is the mechanism hypothesized by Darwin for evolution. Because natural resources are finite, organisms with heritable features that benefit survival and reproduction will tend to leave more offspring than their contemporaries, increasing the frequency of the traits over generations.
Natural selection causes populations to adapt to their environments over time, or become increasingly well-suited to them. Natural selection is influenced by the environment and necessitates the presence of heritable variation within a group.

30. what are the requirements for evolution by natural selection
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
