Evolution

What all the ideal non-real conditions of the Hardy-Weinberg equilibrium predict; no evolution takes place. Mating is assortative, non-random in the real world and sexual selection is at work when assortative mating takes place, thus evolution.

Natural selection is a key process of evolution, where individuals with advantageous traits are more likely to survive and reproduce, leading to the passing on of those traits to future generations. This process results in changes in the genetic makeup of a population over time, ultimately driving the diversity of life on Earth.

DNA can be used as evidence of evolution by comparing the genetic sequences of different species. Similarities in DNA sequences suggest a common evolutionary ancestor, while differences can indicate how species have evolved and adapted over time. By analyzing mutations and genetic variations, scientists can infer evolutionary relationships between species.

One possible process is abiogenesis, where simple organic molecules gradually formed more complex structures, eventually developing into the first cells. This could have occurred through a combination of chemical reactions, environmental conditions, and natural selection over billions of years.

I would say that it more an effect that living systems produce as a result of reproduction than a property. But yes, one could say that an emergent property of life is that it evolves.

Yes, in fact many, many times. There is much more evidence supporting Creation, meanwhile evolution has too many impossible components associated. Any way you put it, life springing from amino acids is impossible, because the cell would die. Also, if monkeys evolved into humans, why are monkeys still existing? The so-called fossils have all been either individually disproven or just fragments of a skeleton, like teeth.

In itself, it isn't. The geological column is a principle used in the preliminary dating of geological features relative to other features. Palaeontology uses estimates gained through geological dating to establish timeframes for the emergence of particular forms in the fossil record. These timeframes in themselves also aren't evidence for common descent, in themselves. What is evidence for common descent is that derived forms are almost always found in geological features that are younger than the layers the oldest basal forms are found in. For example: no primates before mammals; no apes before primates; no humans before apes; and so on.

Yes, the theory of naturalistic evolution, which states that species change over time through natural selection acting on random genetic variations, is widely accepted in the scientific community as the best explanation for the diversity of life on Earth. Through empirical evidence from various fields like paleontology, genetics, and comparative anatomy, scientists have been able to support this theory.

The Urey-Miller experiment proved the validity of the creation of complex organic molecules from the primordial soup of early Earth. With the energy from an electric discharge, the primordial soup - which consists mainly of ammonia, water, and some carbon dioxide - can be changed into amino acids, the base monomer of proteins. The experiment thus shows that the "ingredients" necessary for life could have been created on early Earth, providing a possible framework for the emergence of life.

Evolution is the general theory itself, by which organisms change and adapt over time. Convergent evolution is a specific proces in which similar traits appear in unrelated organisms. For example, insects and birds both have wings but the two evolved independent of each other. That's convergent evolution.

Scientists believe that modern humans, or Homo sapiens, appeared in Africa around 200,000 years ago. This is based on genetic and fossil evidence that indicates the origin and migration patterns of early human populations.

Evolution is not a theory it is a fact. Recognised as such by most sensible people and many religions.

There are several theories of how and why evolution proceeds

"oh ok...

im just doing a science assignment on evolution and that's one of the questions we have to cover, although i do go to a christian school"

The theory is that the original Eukaryotic cell came about by the consumption of a Prokaryotic cell by another Prokayotic cell. This smaller cell was incorporated into the processes of the other - thus forming a symbiosis.

This theory is supported by the fact that chloroplasts and mitochondria have their own DNA (separate from the nucleus).

Yes, when stabilizing selection is acting, individuals with extreme phenotypes are selected against, leading to an increase in the frequencies of intermediate phenotypes within a population. This process helps to maintain the overall consistency of a particular trait or characteristic over successive generations by favoring individuals with traits closer to the population average.

The theory of evolution has many criticisms but none have proven evolution wrong. For example, some people argue that the bacterial flagellum is 'irreducibly complex' and therefore can not have evolved, even though the evidence shows that it not only could have, but has.

Cell theory is important because without knowledge of cells it would be harder to fight diseases, and we wouldn't know anything about most living things or about how our organ work at the microscopic level and wouldn't know how we evolved and with out it we wouldn't have known we had evolved( because we wouldn't no what precursors to the first animals, plants, and fungi are.) Real life applications: Germ theory of disease, Autoimmune disorders, etc...

Evolution is important because of evolutionary medicine, without which we would not know how to stop the evolution of disease resistance in bacteria and artificial selection which is the selection and breeding of organisms for a purpose, and evolutionary algorithms and also may help in learning what gene does what in the organism. Real life applications: figuring out what gene does what, Evolutionary medicine, Artificial selection, Evolutionary Algorithms, etc...

Genetics can help understand genetic diseases, and mendelian genetics can help us understand the inheritance of gene disorders and hopefully in the future help us to correct them.

Homeostasis can also help us stop disease as well and is important for organ donors and organ receivers.

Ecology is important because it makes sure we don't ruin the environment and will be needed in the possible crisis that we appear to be headed for...

I'm unaware of a sixth theme.

I can distinguish creation theory by saying that it is not a theory, but an ideology that has not a scintilla of evidence in support of it. Evolution, the change in allele frequency over time in a population of organisms, is a fact. The theory of evolution, which is the nonrandom survival of randomly variant replicators, explains the fact of evolution. Naturally, man, being a animal is subject to evolutionary forces.

True. Natural selection favors physical adaptations that improve an organism's ability to survive and reproduce, increasing the likelihood that those traits will be passed on to future generations. This process leads to the accumulation of advantageous traits in a population over time.

A bottleneck can reduce genetic diversity by decreasing the population size, leading to a loss of alleles. This can increase the likelihood of genetic drift and limit the ability of the population to adapt to changing environments. It can also increase the frequency of deleterious alleles due to random fluctuations in the small population.

It is highly unlikely that humans could evolve gills, as this would require drastic and improbable genetic changes. Humans are adapted to breathe air, and developing functional gills would involve significant alterations to our respiratory and circulatory systems. Additionally, the evolution of such a complex trait would likely take millions of years, if it were possible at all.

Natural selection is the evolutionary process primarily responsible for the evolution of species. It involves the differential survival and reproduction of individuals with favorable traits that help them adapt to their environment, leading to changes in the genetic makeup of populations over time.

To my limited knowledge of the scientific theory of the origin of man is that at some stage of earth's creation some form of life crawled from the sea. Many years later it became man through various stages of evolution. If one accepts this as being but one theory then one must accept that there are others. Remember that a theory does not contain all truth, but as the term suggests it is but a theory and is likely to change as new evidences are found.

If however one brings God into the equation then one will be bought nearer to the truth, that some power greater than man could organise man from the dust of the earth and put into him his spirit so that he became a living soul. One must also be mindful that the eagerly sought after "Missing Link", that is when the beast eventually became man has never been found.

Fruits aid in the dispersal of angiosperm seeds by attracting animals with their sweet taste and bright colors. Animals eat the fruits and either digest and excrete the seeds elsewhere or drop the seeds while moving. This helps seeds spread away from the parent plant, increasing their chances of germination and growth in new areas.

Evolution is a widely accepted scientific fact supported by substantial evidence from multiple fields, including biology, paleontology, and genetics. The theory of evolution explains the diversity of species on Earth through processes like natural selection and genetic mutation. While some may challenge aspects of evolutionary theory, the overwhelming consensus among scientists is that evolution is a valid and comprehensive explanation for the development of life on our planet.
