SO IT SAYS READ the text and say how the adaption is occured in hummingburs and how they were savory flavors but now they are sweet sensing now how it got adapted make a cer How did the presence of an adaptation change the frequency of a specific trait in hummingbirds? This will be graded based on your overall claim and supporting statements, use of evide from the text, and your encreasoning (CER).
Most humans enjoy candy, cake, and ice cream. As a result of evolutionary history, we have a wide variety of tastes. This is not true of all animals. Cats do not seek sweets. Over the course of their evolutionary history, the cat family tree lost a gene to detect sweet flavors. Most birds also lack this gene, with a few exceptions. Hummingbirds are sugar junkies.
Hummingbirds evolved from an insect-eating ancestor. The genes that detect the savory flavor of insects underwent changes, making hummingbirds more sensitive to sugars. These new sweet-sensing genes give hummingbirds a preference for high-calorie flower nectar. Hummingbirds actually reject certain flowers whose nectar is not sweet enough!
