Charles Darwin

Darwin

was an inquisitive man. Sure he was curious about nature and all that

science stuff, but he's also a guy. So when he saw strange animals, he

often wondered what they would taste like. The difference between Darwin

and the rest of us is that he actually ate 'em!

"Principles of Geology" is a seminal work by Charles Lyell, published in the 19th century. It laid the foundation for modern geology by introducing the concept of uniformitarianism, proposing that the Earth's geological features are the result of gradual processes that continue to operate today. Lyell's work influenced Charles Darwin's theory of evolution and had a profound impact on the development of the Earth sciences.

Let us use tallness in men and women as our example.

In stabilizing selection a normal distribution of heights would be expected as the selective environment would not select against having all variants present in the population.

In directional selection you would see men and women getting increasingly taller ( or, perhaps shorter ) as natural selection selected the variants that were more reproductively successful in the immediate environment. ( say women's mate choice went into overdrive for tall men )

Disruptive selection is the distribution of traits that are at either tail of the distribution. Both short and tall people are represented, but no intermediates. These two dichotomous traits are seen in nature when one species feeds on two different food sources in the same area. Rather like small and large beaked birds. How humans could go through disruptive selection I leave to your analysis.

The concept of "radiant evolution" does not exist in Darwin's theory of evolution by natural selection. Darwin's theory emphasizes the process of natural selection acting on heritable traits within a population, leading to changes in the frequency of traits over generations. This process results in the gradual adaptation of organisms to their environments.

The theory of fossil formation does not conflict with beliefs held by many Christians. Christians generally believe that God created the world and its processes, so the formation of fossils over millions of years can be seen as part of God's creation. The theory does not necessarily challenge core theological beliefs.

Organic evolution is the process by which the genetic makeup of a species changes over time.

There are several mechanisms by which this can happen: natural selection, genetic drift (chance), migration and mutation.

So natural selection is one possible way in which evolution can take place.

Most biologists agree that natural selection is the most important mechanism of evolution. This mechanism was first discovered by Charles Darwin and, independently. by Alfred Wallace.

Gregor Mendel's experiments with pea plants in the 19th century established the principles of heredity, demonstrating that biological traits are inherited according to specific patterns. He showed that genes come in pairs and are inherited from both parents, and his work laid the foundation for the science of genetics.

Higher the genetic variation, better luck to deal with wider range of environmental factors hence better luck to pass the sieve of natural selection.

ALSO

Organisms (plants, animals, bacteria, etc) that have more traits that are favorable in the environment will live longer and have more opportunities to reproduce and create offspring that share their favorable traits. Organisms with traits unsuitable for the environment will die sooner, and will produce fewer or no offspring. If given enough time in a stable environment, the population will eventually reflect the genes best suited for it, assuming pure natural selection.

Fossils are not used to oppose the theory of evolution. They acutually support it in every way. So far not one fossil has been found that is not exactly where you would expect it to be if evolution were true. As we dig deeper we go further back in time and see by piecing fossils together how organisms evolved over time. Although we don't need fossils to support the fact that evolution is happening, it's a nice bonus to have in support of the theory.

Darwin's theory of evolution by natural selection was better than other theories of his time because it provided a mechanism (natural selection) to explain how evolution occurs. It was supported by evidence from various scientific disciplines such as geology, paleontology, and morphology. Additionally, Darwin's theory was able to explain the diversity of life on Earth in a simple and elegant way.

Cambridge University was founded in 1209 by scholars who left the University of Oxford. It started as a few autonomous colleges before evolving into the renowned institution it is today.

Intermediaries, such as fossils and genetic evidence, provide a record of gradual changes over time that support the theory of evolution. Fossils show transitions between different groups of organisms, while genetic evidence reveals similarities in DNA sequences among different species, indicating a common ancestry. Together, these sources of evidence help demonstrate the process of evolution and the relationships between species.

there pretty much at the top fossils cant be to far down on the bottom of the earth but who knows what evolutionist say I'm not them and may God Bless them, but that is my conclusion and if my answers wrong please feel free to change my answer.THANK YOU : )

Charles Darwin's idea of how species change over time is called natural selection. This process involves the survival and reproduction of organisms that are best adapted to their environment, leading to gradual changes in the characteristics of a population.

The theory of evolution is driven by the evidence of traits changing in populations over time, as well as the concept of natural selection where individuals with advantageous traits are more likely to survive and reproduce. This theory helps explain the diversity of life on Earth and how species adapt to changes in their environment.

Stasis occurs when a species shows little to no morphological change over a long period of time in punctuated equilibrium theory. This can happen during the periods of stability in between rapid bursts of evolutionary change.

Punctuated Equilibria is a theory proposed by Stephen Jay Gould and Niles Eldredge to explain patterns of speciation in the fossil record. They pointed out that the record seems to show most species undergo long periods of relatively little change (stasis), then undergo rapid bursts of change at irregular (punctuated) intervals. Evolution did not seem to proceed at a stately, constant, slow speed. Gould and Eldredge explained this by taking the standard idea of how species form (allopatric speciation, or speciation in small isolated groups at the periphery of populations) and showing that this process would produce exactly the pattern which is observed in the fossil record. Essentially, evolution and speciation can occur rapidly in small isolated populations, sometimes too quickly for the fossil record to track all of the intermediate forms. The result is what looks like abrupt emergence of forms with little or no transitional stages, when in reality the evolution had occurred through intermediate stages, only too quickly for the slow process of fossilization to capture it.

The term itself refers to the gradual shift of something over time.

More specifically, in biology it refers to the gradual shift in traits in a population as caused by natural selection. Traits which are harmful or cause an organism to have a decreased chance to survive are 'selected against' in that they are less likely to pass on those traits. Likewise, traits which are beneficial cause there to be an increased chance the organism will survive to pass on it's traits.

Lamarckian evolution is based on the notion that changes that happen to an organisms physiology are passed on when it reproduces. Taking this to an extreme to show why it has been discredited, a person who loses their arm during their childhood does not have babies that are born with one arm. With regard to cave fish, Lamarcks theory of evolution argues that they lose their eyes during their life, and pass on this "lack of eye-ness" to their offspring. Modern genetics has further dampened this idea, as acquired characteristics are not carried in genes.

Darwinian evolution argues that, at some point during the cave fishes history, a genetic mutation caused one to be born with no eyes (or more likely, one was born with slightly less functional eyes). These fish, due to the nature of their dark environment, would be at no disadvantage to their fully sighted brethren. Eyes can easily get infected or irritated, so nature may have favoured on the side of the eyeless ones. Over time blind cave fish became dominant, eventually reaching the pinnacle of existence by being discussed on the internet.

Hope that helps.

1. There is variation in individuals within a species

2. Variation ensures that individuals that are better suited to their environment will survive.

3. Traits that assist individuals in survival and allow them to reprduce gradually spread throughout population.

4. Individuals produce more offspring than the local resources can support.

Convergent evolution is the pattern of evolution where two unrelated species develop similar traits due to similar environmental pressures. This can lead to analogous structures in different species that serve the same function, even though they do not share a common evolutionary origin.

In general ... the people who do the selecting have no idea what the consequences of their meddling will be. This form of short-sightedness often results in detrimental results.

It reduces the amount of variation in a species and many activist groups say that we don't have the right in playing God in choosing the direction of a species' development. Also, too close interbreeding to get desired traits means as well as lowering variation, there is an increased risk of passing on genetic

diseases to offspring.

It played an important role, since he used William Paley's Natural Theology to test his naturalistic theory of how adaptations could have been accomplished through the perfecting action of natural selection working on random variations.
