Charles Darwin

One unintended consequence of the theory of evolution is the misconception that it promotes the notion of "survival of the fittest" as a justification for social inequality or unethical behavior. This misinterpretation can lead to misunderstandings about the complexities of evolution and human behavior. Additionally, some may use evolution to support eugenic ideologies, which can have harmful implications for society.

If it is easier or more likely that an organsim is going to survive and reproduce if that organism works together with another or takes advantage of a certain opportunity, natural selection will favor the organisms that are more suited to maintaining their realtionship with the other organism.

Darwin's theory of evolution by natural selection has been widely accepted in the scientific community and has provided a robust framework for understanding the diversity of life on Earth. Over time, new evidence in genetics, paleontology, and comparative anatomy has continued to support and refine the principles of evolutionary theory.

The idea that evolution is a directed process with a predetermined goal or purpose is not part of Darwin's theory of natural selection. Instead, Darwin proposed that evolution occurs through random variation and selection based on the fitness of individuals in a given environment.

Basically, it's marriage to genetics. Early 20th century geneticists thought that natural selection was too weak to take random mutation and do anything with it. The founders of population genetics and systemists in biology by mathematical paraphernalia showed that gradual allele frequency change over time in populations of organisms was possible ( supported by experiment since ) and jumps in mutational events were not necessary.

Plus the fact that Darwin's original theory had a mechanism of heredity, blending, that could not work with natural selection.

Since the natural selection is a theory, we can not apply a theory as a science. Even though some scientists believed in natural selection: think of Nazi scientists, Soviet scientists, etc. They were 100% evolutionist believers. Nobody yet seen atoms but we believe that they exist...strange. We apply faith in some modern science...hmmm...

Yes. Even though Darwin called the Origin " one long " argument " the book was well supported by the evidence of the day and gave ways to falsify the material in the book,. hypothesis for testing and predictions on what would be found that turned out to be quite accurate. So, scientific.

Basically because populations evolve and individuals are selected. Let us assume that a beneficial mutation occurs in a individual organism. Even if beneficial in the immediate environment it must be in the germ line and passed on to progeny who mate with other organisms whose genes must work in concert with the new mutation that then needs to spread far enough into the populations gene pool so that there is a change in allele frequency that leads to, perhaps, some morphological or behavioral change. This can take uncounted generations, or can be a bit quicker. But, never in one jump.

The genetic variation that was favored by natural selection led to the increased frequency of the advantageous trait in a population over time, resulting in adaptation to the environment. This can lead to improved survival and reproductive success for individuals carrying the advantageous variation.

Darwin's theory of evolution by natural selection explains how new species emerge over time. This process involves individuals with advantageous traits surviving and reproducing, passing on these traits to their offspring, gradually leading to the accumulation of beneficial adaptations in a population.

Darwin talked about natural selection, basically it means that the stronger ones survive to reproduce, if they develop an adaptation that works they pass it on. This relates to genes because that's how we pass down traits, so stronger ones are supposed to pass down better genes. and over a very long time a species evolves

Populations of organisms go through natural selection, not individual organisms. Through natural selection, certain traits that provide a reproductive advantage become more common in a population over time, as organisms with those traits are more likely to survive and reproduce.

Charles Darwin became interested in biology and evolution during his time aboard the HMS Beagle. While on this expedition he collected many plant and animal specimens and started seeing some interesting patterns. It was after this trip that he started his serious research, even though it would be several decades until he would propose his ideas on evolution.

Charles Darwin was curious about the diversity of life on Earth and wanted to understand the processes that drive it. He wanted to explain the patterns he observed in nature such as variations among species and the relationship between different organisms. By investigating evolution, Darwin aimed to provide a scientific explanation for the origin and development of species over time.

Charles Darwin's father wanted him to follow a career in medicine or the clergy, so Darwin pursued his studies diligently to earn his father's respect. He also sought the approval of his teacher at Cambridge, John Stevens Henslow, who was an influential figure in his life and mentor in his pursuit of natural history. Gaining their respect helped Darwin to pursue his passion for natural science and eventually develop his theory of evolution.

French naturalist Jean-Baptiste Lamarck's theory of evolution conflicted with Darwin's theory. Lamarck proposed that acquired characteristics could be passed down to offspring, while Darwin's theory emphasized natural selection and gradual change over generations.

Most of Darwin's ideas, such as natural selection and common descent, are widely accepted in the scientific community today. However, some aspects of his work, like the mechanisms of heredity and the pace of evolution, have been refined and expanded upon with more recent scientific discoveries.

Natural selection is, simply put, the nonrandom survival and reproductive success of randomly varying organisms.

Variation

more born than can survive

better adapted selected

traits passed on to progeny

alleles change in populations over time

Evolution was tinkering with gene regulation to drive changes in morphology and physiology. Michael Levine contributed by studying how these changes are regulated by enhancer elements and transcription factors, providing insights into how genetic instructions lead to the development and evolution of different species.

The founder of the theory of natural selection is Charles Darwin. Alfred Russel Wallace independently developed a similar theory of natural selection around the same time as Darwin, leading to both scientists presenting their work together in a joint paper in 1858.

True. Darwin's theory of evolution emphasized the concept of common ancestry and drove biologists to consider evolutionary relationships when classifying organisms. This led to the development of the modern classification system based on evolutionary principles.

Edwin Darwin did not propose a separate theory on evolution. The theory of evolution is commonly attributed to Charles Darwin, who put forth the concept of natural selection as the mechanism driving evolution. Edwin Darwin does not have a notable theory associated with evolution.

Charles Darwin's theory of evolution is considered a scientific theory because it is a well-substantiated explanation of natural phenomena based on evidence gathered through observation and experimentation. It has undergone rigorous testing and has been supported by a wide range of scientific disciplines, making it a foundational concept in biology.

Some have thought so because natural selection was seen to reduce variation by culling unsuccessful phenotypes so that alleles did not change over time in populations. This is no longer thought as much as the rates of mutation are better understood and known to outpace natural selection and that adaptive change can accommodate more than one successful phenotype so that many allels can be fixed in populations gene pools.
