The problem with the theory of evolution by natural selection, according to Nagel, is that it does not provide an understanding of consciousness as a likely product of evolution.
Q. What type of natural selection has occurred?
Types of natural selection: Different types of natural selection can impact the distribution of phenotypes within a population.In (a) stabilizing selection, an average phenotype is favored.In (b) directional selection, a change in the environment shifts the spectrum of phenotypes observed.In (c) diversifying selection.
Q. Is natural selection true?
Natural selection provides the outline of an explanatory theory.” Biologists consider it to be a scientific fact that evolution has occurred in that modern organisms differ from past forms, and evolution is still occurring with discernible differences between organisms and their descendants.
Q. Has one species evolved into another?
One species does not “turn into” another or several other species — not in an instant, anyway. The evolutionary process of speciation is how one population of a species changes over time to the point where that population is distinct and can no longer interbreed with the “parent” population.
Q. Why do scientists use homologies like this as evidence for common ancestors?
Multiple types of evidence support the theory of evolution: Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features).
Q. What is predictive power of evolution?
The concept of predictive power, the power of a scientific theory to generate testable predictions, differs from explanatory power and descriptive power (where phenomena that are already known are retrospectively explained or described by a given theory) in that it allows a prospective test of theoretical understanding …
