3,722 Questions

What percentage of scientists accept the validity of the theory of evolution?

In the relevant fields (biologists), 99.99% accept evolution.

In science generally, the figure is slightly lower, around 98%. Those that disagree usually do so on religious bases, not scientific ones.

Approximatley when did Mendel and Darwin develop their ideas?

Gregor Mendel developed his ideas on genetics in the 1860s through his experiments with pea plants. Charles Darwin developed his theory of evolution in the mid-19th century and published his book "On the Origin of Species" in 1859.

Charles Darwin called the ability of an organism to survive and reproduce is its environment?

Charles Darwin referred to this ability as "natural selection." It is the process by which certain traits or characteristics that help an organism survive and reproduce in its environment become more common in a population over time. Natural selection is a key mechanism of evolution.

How quickly does evolution occur?

The rate of evolution can vary greatly depending on the species and the environmental pressures they face. Some organisms can evolve relatively quickly, such as bacteria that develop resistance to antibiotics within a few years. In contrast, larger and more complex organisms like humans or elephants may evolve over much longer timescales of thousands to millions of years.

Successful reproduction is the fourth step of what selection?

"Successful reproduction" is a key component of natural selection, which is the process by which organisms better adapted to their environment tend to survive and reproduce at higher rates. It is the mechanism that drives evolution by allowing beneficial traits to become more common in a population over time.

Why are some other individuals more likely to survive and reproduce?

Individuals who are better adapted to their environment, have advantageous traits, and are able to compete successfully for resources are more likely to survive and reproduce. These advantageous traits can be inherited and passed on to offspring, increasing their chances of survival and reproduction as well.

What is the mechanism for determining evolution of life?

The mechanism for determining the evolution of life is natural selection, proposed by Charles Darwin. Natural selection refers to the process by which organisms with advantageous traits for survival and reproduction are more likely to pass on their genes to the next generation, leading to the gradual change in populations over time. Genetic mutations also play a key role in introducing new variations that can contribute to evolution.

Why does scientific evidence support scientific theories?

Scientific evidence supports scientific theories through empirical observations, experiments, and data analysis that consistently confirm the predictions and explanations of the theories. Theories are continuously tested and revised based on new evidence, leading to a more refined and accurate understanding of the natural world. Overall, the robustness and validity of scientific theories are demonstrated through the process of evidence accumulation and verification by multiple independent researchers.

What do scientists use to study genetic evidence?

im going to try put this as clear and less sciency as possiable. So bare with me.

When a species elovs into an adapted species, this new trait is a benefit to keep it alive or improve its life. So when a fossil is found it will have simlaries with a modern day animal that it has evoled into.

For example a fossil is found with a hooked beak, dietary sytem and feet like a chicken. If nothing else has more simlaties with it, it will most likely a species that has evolved into chickens. This is not always a relieable way of comparion but it gives a good anylise of the animal.

Hope this helped somewhat. And p.s. look through this yourself children for spelling mistakes before you copy and paste it as ur homework. LOL i know the tricks.

What are the organisms that produce more offspring than their environment can support and that they compete with one another to survive?

These are known as r-selected species. They typically have high reproductive rates, produce many offspring, and have low parental investment. They rely on high population growth to offset high mortality rates and competition for limited resources.

What Christian beliefes were challanges by Darwins natural selection?

Traditional Church (not Christian as Christ did not teach this) belief was that God had created everything in 7 days as described in Genesis and biblical scholars had worked out that this had happened about 4000 years ago.

The advent of Geology as a science and Darwin's theory of natural selection requires an immense amount of time for the species we see around us today to have come into being by small changes to species that existed in the past.

Thus in effect Darwin said that the Earth is far OLDER than the bible says, and that species were NOT created as described in Genesis but that they evolved from life that existed in the past.

This was a direct challenge to Church doctrine and the Church is still trying to recover from it because when people looked at what Darwin had said and tried to disprove his theory they have so fat not been able to do so.

What would be the evolutionary advantage of developing true tissues?

tissues are made up of a group of cells that work together to perform a specific function. Animals with tissues can develop organs, like the kidney. These organs in turn, help the animal maintain homeostasis.

Is the sentence true or false - genetic variation is found only in wild organisms in nature?

False. Genetic variation is found in all organisms, both wild and domesticated, as it is a natural result of reproduction and mutation. Domesticated organisms can also exhibit genetic diversity due to selective breeding practices.

Who was the First to propose a theory of evolution?

Charles Darwin is credited with proposing the theory of evolution through natural selection in his book "On the Origin of Species" published in 1859.

What is heavily influenced by the theory of evolution?

Many fields are influenced by the theory of evolution, including biology, psychology, anthropology, and medicine. Evolutionary theory helps explain the development and diversity of living organisms, the behavior of species, and the emergence of traits that provide advantages for survival and reproduction. It has also influenced concepts such as natural selection, adaptation, and genetic variation.

Which type of natural selection tends to prevent evolution?

Stabilizing selection tends to prevent evolution as it favors the intermediate phenotype and reduces genetic variation in a population. This can lead to the maintenance of a stable population with limited change over time.

Which form of natural selection is most likely to play a role in speciation?

Reproductive isolation through sexual selection is often an important factor in speciation. This type of natural selection can lead to the evolution of reproductive barriers that prevent individuals from different populations from successfully interbreeding, ultimately resulting in the formation of distinct species.

How can the darwinian concept of descent with modification explain the evolution of such complex structures as an aye?

Eyes are easy. Just look at all the intermediates. From eye spots to cup eyes past pinhole eyes all the way to camera eyes. This progression easily shows the concept of descent with modification.

What are 3 causes of variation within a population?

Changes within a gene pool occurring from generation to generation is called microevolution.

Allele frequencies in a population may change due to gene flow, genetic drift, natural selection and mutation. These are referred to as the four fundamental forces of evolution.

Only mutation can create new genetic variation...the other three forces simply rearrange this variation within and among populations.

What age did Charles Darwin become interested in science?

He was actually 32, and although other sites tell you different, my name is Cassidy Darwin. I was related to Charles, and my family told me with their information that has been passed down from the Darwin family. I hope this helped!

Does the existence of intermediate forms support or not support the theory of evolution?

The existence of intermediate forms supports the theory of evolution. These transitional forms provide evidence of how species have evolved over time through gradual changes and adaptations. They demonstrate the idea of common ancestry and the gradual development of new species from ancestral ones.

How do you tell what descent you are?

One way to determine your descent is to research your family history, including information about your ancestors' origins and cultures. Additionally, DNA testing can provide insight into your genetic ancestry and where your ancestors may have come from. Consulting with genealogists or historians specializing in certain regions can also help you learn more about your descent.

Successful reproduction is the fourth step of selection?

Reproduction is a key part of the process of natural selection as it allows the passing on of successful traits to the next generation. Individuals that successfully reproduce contribute their genes to the gene pool, influencing the genetic makeup of future generations. This ensures that advantageous traits are perpetuated within the population over time.

Describe the ideas of Charles Darwin?

Charles Darwin invented evolution, he say on the Galapagos islands that there was the same bird on every island but with different beaks, so he thought that they just adapted to their surroundings. so there's his ideas...evolution is a highly debatable subject, currently there is more evidence against evolution however the scientists that believe in it keep the subject going with small tidbits of info.
