As mentioned in the video, the environment can also affect an organism’s traits. The example of nourishment was used in the case for Spike, as this could affect his growth and size. This can also occur in humans. UV light was not mentioned in the video. How could UV light potentially affect an organism’s trait? Provide one example.
UV light can potentially affect an organism's trait by causing mutations in its DNA. For example, prolonged exposure to UV light can result in a higher likelihood of developing skin cancer in humans. This is because UV light can damage the DNA in skin cells, leading to mutations that can eventually result in the uncontrolled growth of cancerous cells.
UV light can potentially affect an organism's traits, including those of humans. One example of how UV light can affect an organism's trait is through its impact on skin pigmentation. UV light exposure can stimulate the production of melanin, which is the pigment responsible for the color of human skin, hair, and eyes. Increased exposure to UV light can lead to an increase in melanin production, resulting in darker skin coloration. This is an evolutionary response designed to protect the skin from the harmful effects of UV radiation. Conversely, decreased exposure to UV light can lead to less melanin production, resulting in lighter skin coloration. This demonstrates how the environment, specifically UV light exposure, can influence the trait of skin pigmentation in humans.
