  1. Chapter 10 Science Test Notes

  2. Successful reproduction is not a cause of a species to go extinct. • Separation is movements of Earth’s plates which can split a population into groups. • Scientist draw a branching diagram to show how whales are related to other species.

  3. Adaptation helps organisms survive in their environment • Knowledge of genetics did not help Darwin develop his theory. • Comparing the structures and DNA of two species sometimes show that species have common ancestors.

  4. Speciation can create a new species. • When all the members of a species have died out, the species is extinct. • Darwin did not understand the role of genetics in the process of evolution.

  5. Scientists’ knowledge of genetic changes was not a source for Darwin’s ideas about evolution. • In Natural Selection, the process of organisms being better adapted to their environment can survive and reproduce more successfully than less well-adapted organisms. • Evolution by natural selection is affected by genetic variation and environmental factors.

  6. The process by which populations slowly change over time is called evolution. • Separation is what occurs when a population is divided into groups as a result of movements of Earth’s continental plates

  7. If an environment changes and the adaptations of a species don’t help it survive, it may become extinct. • Scientists compare organisms’ anatomy and DNA to support the theory that species share common ancestors.

  8. A spider may produce hundreds of eggs, only a few of which may survive. This is an example of overproduction. • Populations with low genetic variation may have trouble becoming adapted to their environment.

  9. Take a Two Minute Break

  10. Whales possibly inherited hip bones from a four-legged ancestor. • Adaptation can help an organism survive. • The fact that an organism’s offspring are not identical to each other is due to inherited variation.

  11. A timeline of life indicated by traces or remains of organisms found in Earth’s crust is called the fossil record.
