UNIT 1 – LESSON 2 NOTES Natural Selection and Evidence for Evolution: The mechanism for evolution is called Natural Selection to distinguish it from Artificial Selection. Evolution occurs at the population level because genetics don’t change. The frequencies of different genetic types (genotypes) within a population do change over time & can create new species. There is genetic variation in all populations; some individuals are successful at surviving and finding resources & produce

The Theory of Evolution by Natural Selection has been highly scrutinized since its first publication in 1859. The theory states‚ “the process by which organisms change over time as a result of changes in heritable physical or behavioral traits. Changes that allow an organism to better adapt to its environment will help it survive and have more offspring”. This theory is the basis of all biological sciences‚ and it lays the foundation for various scientific schools of thought. However‚ as in all things

specific environment. Contrary to the beliefs of early philosophers and scientists‚ an organism’s compatibility to its environment is caused by natural selection. Natural selection‚ the process in which individuals with certain heritable traits survive and reproduce at higher rights‚ improves an individual’s ability to adapt to their environment. Natural selection may improve an organism’s ability to survive and reproduce in its environment‚ however‚ the evolutionary process is recognizable because

Most would tell you they would like to see that‚ yet in their mind they know it isn’t possible. All know that when nations are all not democratic‚ this concept makes the world go round.

TOK Essay Natural Sciences - How far do expectations influence observations? Alysia Francis In my opinion I believe that expectations influence or observations greatly. If we think something will happen we are more likely to look hard for it. If we want something to appear then it is more likely that we will think that we see it. An example of this is when people hallucinate. Someone is more likely to see a ghost if they believe or are expecting to see one. In natural sciences when looking

he consequences of natural selection for all the species that do not vary and that are genetically identical is that the environment around them may cause them to go extinct. The environment has many powerful factors that play a role in natural selection. 2. Thomas Robert inspired Darwin and Wallace to write the theory for natural selection. He was an English clergyman and economist. The essay was about the increase and decrease of resources and population. It said the while the mankind population

Substantive law is the statutory or written law that defines rights and duties‚ such as crimes and punishments (in the criminal law)‚ civil rights and responsibilities in civil law. It is codified in legislated statutes or can be enacted through the initiative process. Substantive law stands in contrast to procedural law‚ which is the "machinery" for enforcing those rights and duties. Procedural law comprises the rules by which a court hears and determines what happens in civil or criminal proceedings
