Final answer:
Yes, earthworms have sensory organs that allow them to sense and respond to stimuli such as light and touch. Though lacking complex eyes, some worms have eyespots for light detection. The complexity of sensory organs varies among species and is driven by natural selection.
Step-by-step explanation:
Earthworms do have sensory organs that allow them to respond to various stimuli. They possess a simple brain that enables them to sense and respond to light and touch. While earthworms do not have eyes like humans, some worms, such as the Dugesia flatworm, have eyespots that can detect light in their environment.
Insects, another group of invertebrates, have more complex sensory organs, including a pair of antennae which can detect chemicals, sound, and in some species like butterflies and bees, even color. Higher organisms can have even more advanced sensory systems, like the shark's electrosensitivity, which allows it to detect electrical fields in the water produced by other animals.
As we observe the diversity in the animal kingdom, we see that the sensory systems are tailored to each species' needs, driven by natural selection. This adaptability is evident as we compare the simple sensory system of earthworms to the more complex one found in insects or the specialized electrosensitivity in sharks.
