What are the new evidence of evolution?
New since when?
The answer may include anything from new palaeontological evidence (eg. fossils and such) to new geophysical findings to the advent of genetics and new findings in the fields of genetics and genomics to the latest findings based on the mathematical modelling of population dynamics and population genetics, and so forth, and so on.
Perhaps a more specific question might help.
At the time some scientists did reject the theory, but by the end of Darwin's life the theory was, tentatively, accepted. Then genetics took off and the theory was panned again. 1900 t0 1932. Then the modern synthesis arose blending genetics with systematic thought, paleontology and botany and the theory of evolution by natural selection was on much firmer footing The theory has undergone many modifications since Darwin's day, as any scientific theory does, but, aside from some minor scientific challenges, the theory is still standing more than 150 years later.
What is evolution and what does it involve?
Evolution is the change in allele frequency over time in a population of organisms; change over time. This is all that it involves and whether the driver of evolution is natural selection, the adaptive driver of evolution, genetic drift, a random process or gene flow between populations, gene frequencies in these populations change and that is all evolution involves.
Now, how evolution occurs with it's various drivers is another question for another time.
What is true of macro-evolution?
It is true that speciation occurs. Since macro-evolution is defined as evolution at and above the species level, this makes the statement that macro-evolution occurs an independently verifiable fact.
It is also true that in biology we find nested hierarchies at every level - both at the range of observation from the molecular to the morphological, and at the range of groups from the single species to life-kind in general. This is precisely what we would expect if common descent were true not just within the genus, but for all known life.
Furthermore, it is true that we find morphological intermediates in the fossil record: forms that are intermediate morphologically between basal clades in the nested hierarchies of life and clades derived from those basal clades. A basal clade is a group of organisms linked by shared features; a derived clade is a group within that larger group that shares all those features, but is also linked by a distinct set of features present only within that smaller group. An example of this is the basal clade of Apes, and the derived clade of Great Apes, between which exists, for instance the transitional form Pierolapithecus catalaunicus. This, again, is exactly what we would expect to find if macro-evolution were not just true for minor taxa (eg. within a genus), but for all taxa, throughout time.
There are many statements about macro-evolution that have been verified through observation. The complete list of possible truths about macro-evolution is too large to detail in a single answer.
How does evolution take place within the species?
Evolution within a species occurs through the process of natural selection, where individuals with advantageous traits are more likely to survive and reproduce, passing on those traits to future generations. Over time, these small changes in gene frequencies accumulate, giving rise to new traits and ultimately leading to the evolution of the species.
Was Charles Darwin's contribution negative or positive?
What are facts about Charles Darwin theory of evolution?
Fact #1: Darwin's theory of evolution proposes that populations of organisms originating from a shared common ancestor diverge, producing new species.
Fact #2: Darwin's theory of evolution proposes that the most important mechanisms driving the divergence of populations are reproductive variation and differential reproductive success.
Fact #3: Darwin's theory of evolution proposes that, following #1, all known life on Earth is ultimately related through descent.
A gratuitous fact #4: The modern theory of evolution is no longer limited to Darwin's original proposals. New facts have been found, new mechanisms proposed, and existing models and hypotheses refined to accommodate the new data.
How does it require faith to believe in evolution?
Evolution doesn't require faith. Faith is confidence or trust in a person, thing, deity, or in the doctrines or teachings of a religion. It is also belief that is not based on proof. - Dictionary.com But theory of evolution. A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of knowledge that has been repeatedly confirmed through observation and experiment. - National Academy of Sciences.
What the different type and rates of evolution?
As for types of evolution: within the context of biology, there's only one accepted model for evolution: the model that explains evolution in terms of population genetics, pioneered by Charles Darwin.
As for rates: according to the punctuated equilibrium model, the rates of divergence can vary wildly. Species can exist for hundreds of thousands of generations, with only superficial morphological change, and then in the space of a mere ten thousand generations branch off into distinct separate morphologies.
What evidence for evolution best supports all the other theories?
There are a number of observations in biology that might also play a role in confirming other theories in the natural sciences.
For instance, in palaeontology it is observed that several extinct lifeforms can be found on the edges of continental plates separated by wide oceans. This spread of forms not only supports specific hypotheses related to the phylogeny and evolution of specific lineages, but also serves to confirm hypotheses in plate tectonics.
However, I can think of no observations that would confirm hypotheses in the unifying model of biology as wellas in quantum physics and cosmology andgeology. I think the question may be ill-formatted.
Why can mutation affect evolution?
Mutations are random changes in an organism's DNA that can lead to new traits. These new traits can impact an organism's ability to survive and reproduce in its environment, influencing its chances of passing on these traits to future generations. Over time, accumulated mutations contribute to genetic diversity, which is essential for evolution by natural selection to occur.
What does gradualism and punctuated equilibrium have in common?
That they are both theories of evolutionary change, but the tempo of the change is different enough that we have the two theories. Rapid evolutionary change punctuated with long periods of stasis describes the former while gradual and incremental change over long periods is the description of the later. Natural selection seems to be more important in gradualism than punctuation, but this is a murky area that is argued about often.
How did Oparin's hypothesis help Miller and Urey?
Oparin's hypothesis proposed that Earth's early atmosphere could have supported the formation of organic molecules, providing the foundational idea for Miller and Urey's experiment. Miller and Urey's experiment aimed to simulate early Earth conditions and demonstrated that organic molecules, including amino acids, could indeed be produced in a laboratory setting, supporting Oparin's hypothesis.
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.
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.
