Why was variation the weakest concept in Darwin's theory?
Variation?!?! That was an obvious observation of naturalists that opposed Darwin's concepts totally. Unless you mean the heritability that leads to variation? Explaining that variation was the problem. Creationists of the time explained this by positing god's whimsy in designing his species, but this was shown to be nonsense as natural processes are at work in variation and this can be shown experimentally. The concept of natural selection explained how that natural variation was selected on beneficial traits. What Darwin did not understand is how that variation was passed on to progeny. His explanation was wrong.
How did the modern study of genetics at that Darwin's original theory of evolution?
The modern study of genetics has provided evidence to support and refine Darwin's original theory of evolution. Discoveries in genetics have shown that variations in genes can lead to variations in traits within populations, which can be acted upon by natural selection, ultimately driving evolution. This integration of genetic principles with evolutionary theory has provided a more comprehensive understanding of how species change over time.
What are some of the different theories of evolution?
There is only one central "theory of evolution", which is the theory of evolution by natural selection that Charles Darwin pioneered. There have been different theories in the past - such as Jean-baptise Lamarck's theory of acquired traits - but these lost their status of scientific theory when they were shown to be wrong.
What are three myths about evolution through natural selection?
Answer: Many, even the majority, who follow Darwinian evolution by natural selection would not agree that there are any myths connected with it. That said, real science, with solid evidence to back it up would produce a number of possible answers to this question: 1. Natural selection does not explain the adding of new genetic information into the genome of organisms that enable the changes that evolution believes happen such as the change from dinosaurs into birds. this has never been demonstrated scientifically. Famous evolutionist Richard Dawkins was asked about this issue some years ago and had no answer, no example of an information adding mutation. So this is one 'natural selection myth.' 2. Another seeming "myth" -Natural selection culls out the sick and the weak -the work done by predators. In fact scientific studies on the 'chase-kill response' in predators shows they prefer to attack healthy individuals. We are here talking about predators such as lions, tigers, cheetahs etc. and their prey. This may be that they are attracted to a chase which is not provided by a sick or weak prey and they may also be wary of disease in weak individuals, which also may not provide a good lot of meat they are after. 3. Another myth (assuming we are talking about the modern evolutionary synthesis which includes mutations) is that mutations actually provide new information -they in fact are shown in modern studies to be degrading the genome. this is particularly shown to be so in humans -probably the most studied of the 'higher organisms". Human geneticists are agreed that the human genome is degrading not getting better, through mutations. This is because by far the majority of mutations are of small effect and so are not 'noticed' by natural selection. This effectively means the human genome is deteriorating like rust accumulates on a car over time.
Can you explain the relationship between absorbance and wavelength in a graph?
In a graph, absorbance is typically shown on the y-axis and wavelength on the x-axis. The relationship between absorbance and wavelength is that as the wavelength of light increases, the absorbance generally decreases. This is because different substances absorb light at specific wavelengths, so the absorbance of a substance can vary depending on the wavelength of light being used.
What form of natural selection is shown on a graph as selection against an extreme?
Directional selection is shown on a graph as selection against an extreme. This occurs when individuals at one extreme of a trait distribution have lower fitness than individuals with intermediate phenotypes or those at the opposite extreme. Over time, this can lead to a shift in the average phenotype of a population.
What type of graph is shown?
pie graph
Information in a circle graph is often shown as?
Information in a circle graph is often shown as percentages.
How does a graph showing speed differ from a graph showing acceleration?
Speed can be shown on a graph of position versus time, and acceleration can be shown on a graph of speed versus time.
What does the equillibrium point on a supply and demand graph represent?
which is true about the functional relationship shown in the graph
What variables are shows on the graph?
Any variables can be shown on a graph.
What is the axis of symmetry of the function shown in the graph?
I regret that I can see no function shown.
Which form of natural selection is shown on the chart stabilizing disruptive or directional?
To determine which form of natural selection is represented on the chart, it would be essential to examine the characteristics of the population depicted. Stabilizing selection favors average traits, disruptive selection favors extreme traits, and directional selection favors one extreme over the other. Without seeing the chart, it’s impossible to specify which type is shown, but you can identify the type by looking for these patterns in trait distribution.
Once a graph has been created would y?
Once a graph has been created, y would be the axis which is shown up and down on the graph. The x axis is shown from left to right on the graph. Both are reference lines on a graph.
What conclusion can be drew from the information on the graph?
What conclusion can be reached by the data shown on the graph?
What process produced the two different types of beaks shown?
The process of natural selection produced the two different types of beaks shown. In this case, the environmental conditions likely favored different beak shapes for different tasks, such as cracking seeds or probing for insects, leading to the evolution of distinct beak shapes in the population.
