What evolutionary pressures would lead to Elves?

In my story Elves, Humans, and a bunch of other fantasy races live along side each other and i'm curious as to what evolutionary pressures would to a group of divergent hominids to evolve into Elves? some basic characteristics of my Elves are:

• are on average 158.4cm (5.2ft) tall and weigh 40kg (90lb)
• live on average between 250 and 270 years (addressed here)
• have pointy ears
• are as intelligent as humans
• have an improved sense of hearing and eyesight
• are overall weaker than humans but do have a slightly stronger grip
• are faster and more agile
• have slightly worse endurance (but not as poor as an Orcs)
• are more slender
• are less fertile

Note: magic does not exist in my story
