Darwin vs. Lamarck --Lesson 3 Evolution

Front

What is Darwin's theory of evolution by natural selection?

Back

Darwin's theory states that organisms with traits better suited to their environment are more likely to survive and reproduce, passing those traits to the next generation.

Front

What is Lamarck's theory of evolution?

Back

Lamarck's theory suggests that organisms can pass on traits acquired during their lifetime to their offspring, such as a bodybuilder's muscles.

Front

How do flashy colors in butterflies support Darwin's theory?

Back

Flashy colors can attract mates, leading to better reproductive success for those butterflies, which aligns with natural selection.

Front

What is an example of a trait that Lamarck would say could be inherited?

Back

A heron's long thin legs, which Lamarck would argue developed due to the heron stretching to wade through water.

Front

What is antibiotic resistance in bacteria an example of?

Back

Antibiotic resistance is an example of Darwin's theory, as bacteria that survive antibiotics can reproduce and pass on their resistant traits.

Front

What does the term 'natural selection' mean?

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is the difference between Darwin's and Lamarck's views on evolution?

Back

Darwin believed in natural selection, while Lamarck believed in the inheritance of acquired characteristics.

Front

Can acquired traits be passed down according to Darwin?

Back

No, Darwin's theory states that only genetic traits can be passed down, not acquired traits.

Front

What is an example of a trait that Darwin would say is inherited?

Back

The beak shape of finches, which evolved based on the food sources available in their environment.

Front

How does the concept of 'survival of the fittest' relate to Darwin's theory?

Back

It refers to the idea that the fittest individuals are those that are best adapted to their environment and thus more likely to survive and reproduce.
