Giraffes have long necks because their ancestors stretched their necks reaching for food, and this trait was passed on their offspring.
Which theory sound like an explanation that Bismarck might give
A "theory" is a scenario of what might be.
there might not be enough proof
scapegoat theory
The primary difference between Darwin's and Lamarck's approaches to evolution (if I remember correctly) was that Darwin believed that evolution operated primarily through breeding and death: members of a species that have unproductive characteristics tend to die early and have less opportunity to produce offspring, and so their characteristics are not passed on to future generations. Lamarck, by contrast, thought that environmental conditions could exert a direct (if slight) influence on the genome, so that parents would tend to produce offspring that were better suited to the environment they lived in. For example, Darwin would explain the thick fur and subcutaneous fat deposits of cold-climate animals by saying that members of the species with less fur and fat would die more easily and earlier in cold weather; Lamarck would explain the same result by saying that the cold climate induced the organisms to produce more fur and fat, and their offspring would be born with a greater capacity to produce those things than their parents. Lamarck's theory has not been disproved - scientists still do not have a clear understanding of the process of evolution - but for various non-scientific reasons it is less accepted in the scientific community (primarily, I think, because it opens the door to a teleological argument abut the nature of species that most scientists find distasteful). It is important to point out that Darwin's theory was that of Natural Selection and The Origin of Species, and he was not proposing any system separate from or one that discredited classical Creationist theory. Jean-Baptiste Lamarck, however, coined the phrase Evolution.
Darwin might give an explanation based on the theory of natural selection, which suggests that organisms best adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to future generations. This theory forms the core of Darwin's theory of evolution.

No, a theory is not a prediction. A theory is a well-supported explanation for a phenomenon based on evidence and research, while a prediction is a statement about what might happen in the future based on the theory.
Lamarck's theory of evolution proposed that traits acquired during the lifetime of the parent were genetically passed on to children. Some animal might, according to Lamarck's theory, learn a novel way of obtaining food, and then its children would be born with this novel mechanism already in place. Darwin, contrarily, proposed that lineages evolved new traits though natural selection: by the elimination of lineages that do *not* possess a certain trait.
a theory is an explanation to a specific question being studied. it has been tested many times. it might be replaced with a new theory because new information come and so the past information will be improved.
Yes. If you have a theory about how things work, it might turn out to be true or it might turn out to be false. The more you know about the subject, the stronger the theory is likely to be, and the likelier it is that the theory will be proven.
Lamarck's theory cannot be true since characteristics of an organism are determined by its DNA and also over time how this is expressed through the epigenetic code. This theory is wrong.
A "theory" is a scenario of what might be.
A suggested explanation that might be true and is subject to testing by further observations is
A fact is something that can be checked and proven. A theory is a possible explanation for something. When discussing a theory, speculative words and phrases are often used such as: may: It seems /Appears.. We suspect.. Might It's possible.. We think/believe.. Could For good music: www.1musica.com
Just say sorry You might want to add a reasonable explanation.
