Natural Selection and Evolution Concepts

The video tutorial explains Charles Darwin's theory of natural selection, highlighting how organisms better adapted to their environment survive and pass on their genes. It discusses the role of adaptation, survival, and mutation in evolution. The video also covers the initial rejection of Darwin's theory due to religious beliefs and lack of scientific explanation at the time. It contrasts Darwin's ideas with Lamarck's theory, which was eventually rejected. The tutorial concludes with a summary of both theories and encourages viewers to engage with the content.

Who proposed the theory of natural selection?

• Gregor Mendel

• Charles Darwin

• Albert Einstein

• Isaac Newton

What does 'survival of the fittest' mean in the context of natural selection?

• Survival is based on luck

• Only the largest organisms survive

• Organisms that adapt better to their environment survive

• The strongest organisms always survive

How does natural selection provide evidence for evolution?

• It suggests that evolution is a myth

• It proves that all organisms are identical

• It demonstrates that complex organisms evolved from simpler ones

• It shows that organisms never change

What are the two main factors that drive natural selection?

• Climate change and food availability

• Environmental changes and mutations

• Human intervention and natural disasters

• Predator presence and prey availability

What is a mutation?

• A change in an organism's diet

• A change in DNA leading to new characteristics

• A change in an organism's habitat

• A change in an organism's behavior

Which of the following is an example of a beneficial mutation?

• A rabbit with smaller ears

• A rabbit with bigger ears for better hearing

• A rabbit with a new fur color that stands out

• A rabbit that cannot run fast

Why was Darwin's theory initially rejected?

• It was too similar to other theories

• It contradicted religious beliefs

• It was not published

• It was too simple

What was a major reason Darwin's theory was not accepted at first?

• Lack of understanding of genetics and DNA

• Lack of evidence for natural selection

• It was not supported by any scientists

• It was too complex to understand

What was Lamarck's theory about the inheritance of traits?

• Traits acquired during an organism's life are passed on

• Traits are randomly passed on

• No traits are passed on

• Only genetic traits are passed on

Why can't characteristics developed through environmental factors be passed on to the next generation?

• They are not encoded in DNA

• They are too complex

• They are not useful

• They are not visible
