Q: Is inheritance of acquired characteristics true?
A: No, there is no evidence that acquired characteristics can be inherited.
Q: What does natural selection propose?
A: That individuals with certain inherited traits leave more offspring than individuals with other traits.
Q: What are vestigial structures?
A: Remnants of features that served important functions in the organism's ancestors.
1. The Darwinian revolution challenged traditional views of a young Earth inhabited by unchanging species.
2. Descent with modification by natural selection explains the adaptations of organisms and the unity and diversity of life
3. Evolution is supported by an overwhelming amount of scientific evidence
4. The geographic distribution of organisms is consistent with evolutionary theory.
5. Organisms share characteristics because of common descent or because natural selection affects independently evolving species in similar environments in similar ways.
Camouflage as an example of evolutionary adaptation.
Related species of the insects called mantids have diverse shapes and colors hat evolved in different environments.
This chapter is basically about evolution, and shows several scientists and previous beliefs and still developing ideas about evolution.
Ideas about change over time include fossils, paleontolgy, catastrophism, uniformitrarianism. Lamarck first provided with his hypothesis. Then, Charles Darwin came up with the natural selection and stuff to back up his idea.
Many evolutions that have to do with ancestors and environments have been contemplated and discovered.
