Environmental pressures Availability food with droughts and global warming available vegetation can be limited. A variation of a giraffe is its long neck
New variations can be created through genetic mutations, environmental influences, and selective pressures. Mutations are random changes in genetic material, while environmental factors can drive changes in traits based on interactions with surroundings. Selective pressures determine which variations are advantageous and become more common in a population over time.
Some environmental pressures are lack of food, droughts, and also carnivores.
Environmental Pressures of a rabbit are lack of food/water
No. Genetics is a topic in biology. I think what you mean is, the mutations that form in DNA to give different features may be beneficial to the survival of the organism. E.g. Giraffes with long necks are more likely to survive than the giraffes with short necks because they can reach leaves on higher trees but the short giraffes can not. The short giraffes have evidently become extinct as a result.

Giraffes face environmental pressures primarily through their unique adaptations, such as their long necks, which allow them to reach high foliage for feeding while avoiding competition with other herbivores. Their spotted coats provide camouflage in the dappled light of their savanna habitats, helping them evade predators. Additionally, giraffes have developed a social structure that includes forming loose herds, which enhances their vigilance against threats. These adaptations collectively enable them to thrive in their diverse and often challenging environments.
The main variation is that each giraffe has an individual spot pattern - no two giraffes ever have the same pattern.
Similarities in any giraffes compared to other giraffes are variation. Basically just explain a giraffe, you would need to compare two things to find out the difference of variation in them.
environmental variations are characteristics which are adapted by your living area. eg: if you move to America, your accent may change

Living organisms face environmental pressures such as competition for resources, predation, disease, and changes in climate. These pressures drive evolution by selecting for individuals with advantageous traits that increase their chances of survival and reproduction. Organisms must adapt to these pressures in order to thrive in their environment.
