A certain species of snail shows variation in its shell coloring from solid yellow shells to Brown bandage shells birds are the main predator of the snail a scientist observed population of the snail in various habitats the data table shows the number of snails of each shell color in a grassland environment
| Shell Color | Number of Snails |
|---------------|------------------|
| Yellow | 100 |
| Brown | 50 |
| Bandage | 25 |
The scientist noticed that in the grassland environment, birds were easily able to spot the yellow snails due to their bright color, making them more vulnerable to predation. On the other hand, the brown and bandage-colored snails were better camouflaged in the grass, making them less likely to be eaten by birds.
This observation could be an example of natural selection in action. Over time, the population of snails in the grassland environment may shift towards more brown and bandage-colored individuals as they have a higher chance of survival and reproduction compared to the yellow snails.
It is important to note that natural selection is just one of the mechanisms driving evolution, and other factors such as genetic drift and gene flow also play a role in shaping the characteristics of populations over time.
