Unit Review #10 Artificial Selection v Natural Selection 24-25

Front

What is artificial selection?

Back

Artificial selection is the process by which humans breed plants and animals for specific traits.

Front

What is natural selection?

Back

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

Front

What is a cladogram?

Back

A cladogram is a diagram that shows the evolutionary relationships among various biological species based on similarities and differences in their physical or genetic characteristics.

Front

Why is decreased diversity in artificial selection a concern?

Back

Decreased diversity can lead to organisms with the same traits being more susceptible to extinction.

Front

What is the advantage of having different shaped beaks in birds?

Back

Different shaped beaks allow birds to eat food that is readily available in their environment.

Front

What are genetically modified organisms (GMOs)?

Back

GMOs are organisms whose genetic material has been altered using genetic engineering techniques to exhibit desired traits.

Front

What is the significance of bone similarities among different species?

Back

Similarities in bone arrangements suggest that these organisms share a common ancestor.

Front

What is the role of selective breeding in artificial selection?

Back

Selective breeding involves choosing specific organisms with desired traits to reproduce, enhancing those traits in future generations.

Front

How does natural selection lead to evolution?

Back

Natural selection leads to evolution by favoring traits that enhance survival and reproduction, gradually changing the species over time.

Front

What is the difference between artificial and natural selection?

Back

Artificial selection is driven by human choice, while natural selection is driven by environmental pressures.
