Textbooks give false information about assumed evolution
This is a typical example of a textbook or a web page providing information about organismal change. According to this site, rapid changes in beak size and shape within Darwin's finches is due to evolution and natural selection. These are the key points represented at the site:
- Darwin observed the Galapagos finches had a graded series of beak sizes and shapes and predicted these species were modified from one original mainland species.
- Darwin called differences among species natural selection, which is caused by the inheritance of traits, competition between individuals, and the variation of traits.
- Offspring with inherited characteristics that allow them to best compete will survive and have more offspring than those individuals with variations that are less able to compete.
- Large-billed finches feed more efficiently on large, hard seeds, whereas smaller billed finches feed more efficiently on small, soft seeds.
- When small, soft seeds become rare, large-billed finches will survive better, and there will be more larger-billed birds in the following generation; when large, hard seeds become rare, the opposite will occur.
- natural selection: a process in which individual organisms or phenotypes that possess favorable traits are more likely to survive and reproduce
- evolution: the change in the genetic composition of a population over successive generations
Claim 1. Darwin observed the Galapagos finches had a graded series of beak sizes and shapes and predicted these species were modified from one original mainland species.
This might be the case. Pretty possible.

Claim 2. Darwin called differences among species natural selection, which is caused by the inheritance of traits, competition between individuals, and the variation of traits.
This is false information. According to modern science, differences among species are caused by epigenetic regulation and inheritable epigenetic memory.
Claim 3. Offspring with inherited characteristics that allow them to best compete will survive and have more offspring than those individuals with variations that are less able to compete.
This is also false information. According to latest research, so called survival of the fittest is due to inheritable epigenetic memory. Organisms have coded mechanisms by which they are able to adapt to changing environment, changing food type etc. Changes occur rapidly and they are inherited to the offspring across multiple generations.
Claim 4. Offspring with inherited characteristics that allow them to best compete will survive and have more offspring than those individuals with variations that are less able to compete.
This is partly false information. Offspring with inherited characteristics are adapted in different way than offspring with less inherited characteristics. However, both groups have potential to survive if proper food is available.

Claim 5. Large-billed finches feed more efficiently on large, hard seeds, whereas smaller billed finches feed more efficiently on small, soft seeds.
This is the most pseudoscientific claim. Darwin thought that beak size and shape changes randomly and that birds with certain beak size and shape are forced to select their food type. Modern science has revealed that food type affects organisms epigenomes causing intentional changes to phenotype, in this case to the beak size and shape. In other words, if a bird starts eating seeds, the offspring will have stronger and larger beaks. This is how epigenetic regulation works. No randomness. No natural selection. No random mutations.
Claim 6. When small, soft seeds become rare, large-billed finches will survive better, and there will be more larger-billed birds in the following generation; when large, hard seeds become rare, the opposite will occur.
This is also based on mechanisms. Organisms are able to regulate the number of offspring along to how much food is available.

Key terms are to be corrected:
Natural selection: An imaginary force that has no true impact on organismal change and biodiversity. Mostly it's just bad or good luck.
Evolution: Organismal change occurs due to epigenetic regulation of pre-existing coded information. No genetic mutations have been associated with beak size or shape within Darwin's finches. Epigenetic regulation results in subtle genetic errors. Gradually this leads to genetic decay, degradation, degeneration and genetic entropy. Evolution never happened.
