Charles Darwin

Darwin's theory of evolution was primarily based on observations he made during his voyage on the HMS Beagle, especially the geographic distribution of species and the fossil record. He also drew heavily on the work of naturalists before him, such as Lamarck and Lyell, and conducted experiments and collected data on variation and natural selection in species.

Charles Darwin's theory of evolution is based on the idea that all living beings have evolved over time through natural selection. This means that individuals with beneficial traits are more likely to survive and reproduce, passing on those traits to future generations. This process leads to the gradual changes in species over time.

Similarities in macromolecules, such as DNA and proteins, among different organisms can be used as evidence to support evolution because these similarities can be used to construct phylogenetic trees that show how different species are related to each other. The more similar the macromolecules are between two organisms, the more closely related they are thought to be, indicating a shared evolutionary history. This provides molecular evidence that supports the idea of common ancestry and gradual evolution over time.

Charles Lyell proposed the theory of Uniformitarianism, which suggests that the Earth's landscape is a result of slow and continuous geological processes that have been occurring over a long period of time. This theory challenged the prevailing idea of Catastrophism, which posited that the Earth's features were formed by sudden, short-lived events.

Charles Darwin is credited with founding the modern theory of evolution with his book "On the Origin of Species" published in 1859. He proposed the concept of natural selection as a mechanism for species' adaptation and survival.

The theory of evolution posits that all living organisms have descended from a common ancestor through a process of natural selection, genetic mutation, and adaptation to their environments. This explains the diversity of organisms on Earth as the result of gradual changes over millions of years. Evolutionary processes help organisms become better adapted to their environments, leading to a multitude of species with different characteristics and traits.

Evolution may refer to both the observed phenomenon and the theoretical framework explaining observations in terms of what we know of that phenomenon. Phenomena need no support, just verification. Theories aren't usually supported by other theories, but by observational data. Just so for evolutionary theory: it's supported by the observations in embryology, genetics, comparative genomics, palaeontology, ethology, zoology, microbiology, molecular biology, and so forth.

1. Variation: Within a population, individuals have different traits.
2. Selection: Certain traits provide individuals with a better chance of survival and reproduction.
3. Reproduction: Individuals with beneficial traits are more likely to pass on these traits to their offspring, leading to a shift in the population's gene pool over time.

High-quality peer-reviewed research studies, meta-analyses, and systematic reviews are types of evidence that best support a synthesis claim. These types of evidence incorporate findings from multiple studies and provide a comprehensive overview of the topic, helping to strengthen the credibility and reliability of the synthesis claim.

The harsher the environment the more natural selection plays a role because the smallest advantage might be enough, hence humans with a very easy environment where genes don't offer a significant advantage this doesn't really count for humans.

And how much a species reproduce, the more they reproduce the more chance for a beneficial mutation.

I would think for the most part birds of a feather flock together. Beautiful people marry each other unless the man has lots of money. Under education people marry each other and produce lower children that will also get limited education.

The idea of evolution is that evolution is a fact and the theory of evolution by natural selection explains much about the fact of evolution.

Your question is ill posed. A more modern phrase would say your question is malformed.

How could the fact of evolution be a threat to anything? How could the theory that is the backbone of biology not be one of the greatest progressions in science?

Much confusion between fact and theory. Theory explains fact and encompasses fact and is a higher scientific concept than fact.

State evolution refers to the process by which a system's state changes over time in response to internal dynamics or external influences. It is often used in the context of systems theory and can involve the transition from one stable state to another or the gradual development of a system's properties. Understanding state evolution is important for predicting future system behavior and making informed decisions.

Scientists were having the same problem that Darwin thought would happen. In Darwin's mind his theory took away the need for a God. Darwin's theory of evolution challenged both the Religious and the science community. Some scientists still have the same shallow mind that other scientists had during Darwin's time.

The natural selection must be near water, near woods but not too close to them, and it really depends on who is living there. People will die without the necessities of life. For example if they aren't near water, they will die from lack of water.

A. Spontaneous generation contradicted the cell theory, as it proposed that living organisms could arise from non-living matter, which is not in line with the principle that all living things are composed of cells.

This lab simulation likely demonstrates evolutionary principles by showing how certain traits or characteristics can lead to survival and reproduction. By simulating the process of natural selection and genetic variation in a controlled environment, it provides evidence for how species can evolve over time through adaptations and changes in gene frequencies. This can help support the theory of evolution by showing how it operates in a simplified model.

The modern theory of evolution combines Darwin's theory of natural selection with our current understanding of genetics to explain how species change over time. It emphasizes that genetic variation, inheritance, and environmental pressures drive the process of evolution. This theory is supported by evidence from fields such as genetics, paleontology, and biogeography.

"Survival of the fittest" is a concept in evolutionary biology that describes the natural selection process where organisms best adapted to their environment tend to survive and reproduce, passing on their advantageous traits to the next generation. It is a key mechanism driving the process of evolution and the adaptation of species to their surroundings over time. The fittest individuals in a particular environment are those that are most successful at reproducing and passing on their genes.

First of all, it should be noted that there isn't really a "theory of macro-evolution". There is the theory of evolution by natural selection, which describes and explains change at both the level of individual lineages, and the pattern formed by branching lineages.

First is the pattern of nested hierarchies formed by all extant life forms. This pattern is apparent from their overall morphology, but also in their behaviour, and ultimately in their genes. The genetic nested hierarchy strongly implies ancestral kinships, and neatly overlays similar classification schemes based on inherited physiological traits or by embryological development.

Second would be the existence of fossils which not only show that change has taken place, but also the type of change, since these fossils too follow similar patterns of nested hierarchies.

Third would be the observation of numerous speciation-events - some having lead to distinct and separate species, and others still in the stage of increasing divergence between subpopulations within the same species.

Fourth would be the observation of "micro-evolutionary" changes, following a pattern that is consistent with what one would expect if the overall theory were true, but from which one must also infer that "macro-evolutionary" divergence must, ultimately, follow.

Fifth, we would expect geographic trends in the diversification of species. The further removed one breeding population is from another, the greater the anatomical differences we would expect to accumulate over time. This phenomenon is asl known as "race circles," and is exemplified by salamanders ranging from California down through Mexico, in rodent species divided by the edges of the grand canyon, and in pigeon populations Charles Darwin noted himself in "On the Origin of Species."

On a larger scale, new world primate populations have a particular dentition distinct from that of old world primates, plus they have prehensile tails. All species of South American primates are platyrrhines, whereas African primates (not including tarsiers, lemurs, and lorises) are catarrhines, with a different tooth structure and without prehensile tails.

All the mammals native to Australia bigger than bats and rats are marsupials. The dingo was likely brought to the island by early aborigines. Evolution explains that the early marsupial mammal form migrated there and thrived without competition from placental mammals for millions of years. Where placentals evolved they gradually replaced most marsupial varieties.

The theory of evolution explains how species change over time through natural selection, genetic variation, and adaptation to their environment. It is supported by evidence from various fields, such as paleontology, genetics, and biogeography, and is considered the central organizing principle of biology.

That a certain animal will have a mutation and if the mutation is more successful then the original then mutation will live if not, then the mutation will die out and also if you split a group of animals up and have say a rat species from Europe and introduce them to a cold climate or an island like Madagascar then they may evolve to better survive in their environment

Charles Darwin was a naturalist who conducted research in the fields of biology, geology, and paleontology. His most famous work, "On the Origin of Species," proposed the theory of evolution by natural selection, which revolutionized the field of biology.

To add to the question:

Some examples are the expansion of European states, global exploration, racial ideals, religious beliefs, politics, slavery, educated elite, associated sciences, and questions on human ancestry and decent.
