Summary:

This video expands on the idea of evolution and how new generations share similar traits as others. The idea of natural selection is discussed and how it influences evolution. Although the video is very brief and does not explain how life started, it explains the history of life and why we are the way we are today.

Why watch this video?

1. Have you ever wondered who created the theory of natural selection?
2. Would you like to know how new generations have different variations than the previous generation?
3. Have you ever been confused by natural selection, and what it is?

Key Terms

1. Evolution- A long process over time in which different forms of life (whether it be animals or people) give different characteristics to new generations causing different genetic changes.
2. Natural Selection- A process involving evolution over time. It is a process that allows different life forms to have different characteristics than each other (ie: different hair colour, eye colour etc.), resulting in differences amongst individuals in new generations, to help each new species better survive and adapt to the environment around them.
3. Generation- All of the people and creatures living in a specific period of time.

Loose Ends

1. Though the video does not expand on evolution a whole bunch (in terms of explaining how we came to be on the Earth), the video more so explains why we are the way we are today. Focusing on how our traits were passed down and how they differ with each new generation. One loose end, is the fact that it does not explain how we evolved and came to be on Earth, which can be confusing to some people, and might want to be explained before explaining why we are the way we are now.
2. When he says the point “biological evolution is about something more” it can be confusing what “more” means. He is expanding again on the fact that evolution does not just tell us how we came to be the way we are today, but also emphasizes on the fact that each generation passes down traits and that we also inherit traits from the generations before.
3. The final loose end is what are the biological rules? The biological rules are patterns that we see from previous generations into the next.

Self Test Questions

Question 1: Who created the theory of natural selection?

Answer A: Darwin and Wallace

Answer B: Darwin and Freud

Answer C: Freud and Erikson

Answer D: Erikson and Darwin

Correct answer: A) Darwin and Wallace is the correct answer because Freud created the psychosexual stage theory and Erikson created the psychosocial stage theory.

Question 2: Darwin and Wallace’s natural selection theory includes three main arguments. Which one is NOT one of the arguments?

Answer A: All life is descended from a common ancestor

Answer B: New generations show variation

Answer C: The more often a trait survives the more common it will become

Answer D: Some generations share all of the same traits with no differences

Correct answer: D) The correct answer is d because it is impossible for a new generation to share all of the same traits as the previous because during evolution traits are passed down all while creating new traits.

Question 3: What does evolution help us understand according to the video?

Answer A: Helps us understand how we came onto the Earth

Answer B: Helps us understand the history of life

Answer C: Helps us understand why we have the personalities that we do

Answer D: Helps us understand why each generation is exactly the same as the previous

Correct answer: B) Evolution tells us how all beings came to be how they are today by the traits passed down through previous generations.

Question 4: Who do the basic biological rules pertain to?

Answer A: Human beings only

Answer B: Animals only

Answer C: No one

Answer D: All creatures big and small

Correct answer: D) The correct answer is d because all creatures big and small all descend from previous generations, which means the biological rules apply to them.

Question 5: Who passes on their traits more often?

Answer A: Any creature that lives long enough to reproduce and create more life

Answer B: Creatures that do not reproduce

Answer C: No creature passes on their traits

Answer D: None of the above

Correct answer: A) The correct answer is “a” because any creature that can reproduce with another creature will pass on their traits.
