What is the mechanism for change in Charles Darwin's theory of evolution?

The mechanism for change in Charles Darwin's theory of evolution is natural selection. This process involves the differential survival and reproduction of individuals within a population based on their inherited traits. Over time, favorable traits that increase an organism's fitness become more common in the population, leading to evolutionary change.

What are the criteria of success in terms of evolution by natural selection?

Success in terms of evolution by natural selection is typically measured by an organism's ability to survive and reproduce in its environment. Traits that enhance an organism's chances of survival and reproduction are favored by natural selection, leading to their increased frequency in a population over generations. Ultimately, success in evolution is defined by passing on genetic material to future generations.

What is the idea that evolution is mathematically impossible?

The idea that evolution is mathematically impossible is a misconception. Evolution is a well-supported scientific theory that explains the diversity of life on Earth through gradual changes in populations over generations via mechanisms like natural selection and genetic drift. Mathematical models and evidence from various scientific fields support the concept of evolution.

Why do you think Darwin considered the phrase the struggle to survive an appropriate description of natural selection?

Because in the wild there is a struggle for existence as more organisms are born than there are resources to support them. Thus, there is a wide variety of traits expressed by these many organisms and some of these traits confer survival and reproductive advantages which is what natural selection is selecting for.

How is Darwin's theory and evolution alike with the flood myth?

Not at all alike.

Evolution is an observed and observable fact. The theory that explains much about evolution is well supported by the evidence and has been repeatedly tested. It also has made many testable predictions.

Flood myth? Whose flood myth? These myths are legion and many cultures have one. Not one of the myths has ever been supported by the evidence though.

How does adaptation affect the evolution of a species?

Adaptation allows a species to survive and reproduce in its environment, leading to the passing on of beneficial traits to future generations. Over time, these accumulated adaptations can drive evolutionary changes within a species, helping it to better suit its environment and potentially leading to the formation of new species.

Are there atheist scientists arguing against evolution?

Yes. A few examples are Jerry Fodor, Massimo Palmarini, Michael Behe, and Thomas Nagel, among others.

Evolution is fraught with difficulties and it remains in fact a theory, open to dispute by people who choose to avoid ignoring its problems. It can neither be proven nor demonstrated in the lab (in its broader sense of giving rise to new organs or species).

Who is the person treated as the father of evolution?

Charles Darwin is considered the "father of evolution" for his groundbreaking work on the theory of evolution by natural selection, outlined in his book "On the Origin of Species." Darwin's theory revolutionized our understanding of how species evolve over time through the process of natural selection.

Why do humans have two nipples?

Actually, the reason men have nipples is because both males and females must carry enough DNA to reproduce humans of both genders. So both males and females have the stem cells needed for growing breasts. But since only females have ovaries, generally only maturing and adult females produce enough estrogen to cause their breasts to grow. Males can on occasion develop fully-mature breasts, and that's usually due to a hormone imbalance or due to medication.

What is the difference between particle swarm optimization and differential evolution?

Differential evolution is when a putati creates a sort of egg that needs to be fertilized therefore creating butt sex between the duck and goose.

However Swarm optimization can be a number of things e.g

- A cake

- A lubricant penis

Any of the sort.

How many kingdoms besides the animal kingdom?

In the traditional, and most widely accepted system of classification, there are 6 Kingdoms, 5 in addition to the animal Kingdom. Most scientists in the United States use this system. The following Kingdoms are used in this system:

Kingdom: Archaebacteria,

Kingdom Eubacteria,

Kingdom Protista,

Kingdom Fungi,

Kingdom Plantae,

Kingdom Animalia.

These are often categorized into 3 domains: Archaea, Bacteria, and Eukarya.

However, United Kingdom, Australia, and South America classify Archaebacteria and Bacteria as Monera so they use only 5 kingdoms.

Moreover, the choice of system, of which there are several, is essentially arbitrary, and now open to a lot of debate among scientists. There is evidence now, that many species have been misclassified. The taxonomic world is in the throes of reorganization. As scientists gain more evidence, especially through genetic investigation, there will be more debate; and, at some point, clarity will be the consequence of this upheaval.

Which type of natural selection occurs when the extreme opposites in a phenotype range are selected?

Disruptive selection occurs when the extreme phenotypes in a population are favored over intermediate phenotypes. This can lead to the divergence of a population into two distinct groups with different traits.

Why is selection considered to be a negative process?

Selection is often considered a negative process because it can result in exclusion or discrimination against certain individuals or groups based on factors such as race, gender, or socioeconomic status. It may lead to unfair advantages for some and disadvantages for others, perpetuating inequalities in society. Additionally, selection processes that are not transparent or unbiased can undermine trust and limit opportunities for diverse talent to succeed.

How does evolution affect migration?

Migration and evolution affect one another.

Migration patterns are usually partly instinctual, which means that they're behaviour-patterns that may change as a result of genetic developments. An example of this is the observed divergence between cohabitating populations of blackcaps in northern Europe: as a result of urban development, parts of the total population have developed differing migratory habits: they spend more time over and in the cities than their sibling subpopulations. Eventually, this situation may result in a decline in interbreeding between the two groups, in turn leading to speciation.

What is clonal selection theory?

Clonal selection theory explains how the adaptive immune system selects and amplifies immune cells (such as B cells and T cells) that are specific to antigens. When a pathogen enters the body, immune cells with receptors that match the antigen are selected for activation and proliferation, leading to a targeted immune response. This theory is fundamental to understanding how the immune system responds to infections and develops immunological memory.

What is the cause of human evolution?

Most believe that the struggle to survive and adaptation causes evolution. If all of the sudden all food was in trees, humans would probably adapt and become skilled climbers, or grow a body part that helps climbing.

Is it true similarities in early development are not evidence for evolution?

Similarities in early development can provide evidence for evolutionary relationships between species. For example, striking similarities in embryos of different vertebrate species support the idea of a common ancestor. These similarities suggest that evolutionary changes have occurred over time, leading to variations in adult forms while retaining aspects of shared developmental processes.

Is similarities an early development not evidence for evolution?

Yes, similarities in early development among different species can be evidence for evolution. This is because these similarities suggest a common ancestry and genetic relatedness among organisms, supporting the idea of descent with modification over time. Studying developmental patterns can provide insights into how species have evolved and adapted to their environments.

What effect does platae tectonics have on evolution of new species?

If a land mass separates and moves many miles away from it's parent land mass you will possibly split apart a species that lived in the vicinity. Geographic isolation ensues and any mutations that happen in the two populations now statistically vary and can not enter a common gene pool, but enter each separate gene pool. This can cause allele frequencies to change in the separate gene pools, among other processes, to begin new species.

What is sequence in the evolution of man?

The sequence in the evolution of humans is generally believed to have occurred over millions of years, starting with our common ancestors with apes, followed by the emergence of early hominids like Australopithecus, leading to the evolution of the genus Homo, which includes modern humans. This evolutionary process involved changes in anatomy, behavior, and culture that led to the development of more advanced human species.

What are the main mechanisms used by secular scientists to explain evolution?

All educated and not ideologically blinded scientists explain evolution by three primary mechanisms. Genetic drift, gene flow and natural selection.

I have the feeling you do not know what secular means.

Why do all organisms face a struggle to survive when natural resources are limited?

Organisms need resources like food, water, shelter, and space to survive and reproduce. When resources are limited, competition among organisms increases as they struggle to meet their survival needs, which can result in some organisms with better adaptations outcompeting others. This competition is a fundamental aspect of natural selection and drives the evolution of traits that enhance an organism's ability to survive and reproduce in its environment.

What are the key requirements for evolution to occur?

The key requirements for evolution to occur are variation in a population, heredity of traits, differential reproductive success based on those traits, and the passage of traits from one generation to the next. This process allows for the accumulation of advantageous traits over time and the adaptation of populations to their environment.

How will the allele change in the rat population?

Allele frequencies can change in a rat population through genetic drift, natural selection, gene flow, and mutations. These can lead to an increase or decrease in the frequency of certain alleles within the population over time.

What are the main principles of evolution according to Charles Darwin and the evolutionists?

The main principles of evolution according to Charles Darwin and evolutionists include natural selection, which is the process by which organisms best adapted to their environment tend to survive and reproduce, leading to the gradual change of species over time. Additionally, genetic variation and inheritance play a key role in driving evolutionary change by providing the raw material for natural selection to act upon. The idea that all species share a common ancestry and have evolved from a single common ancestor is another important principle of evolution.
