In the context of evolution, certain traits or alleles of genes segregating within a population may be subject to selection. Under selection, individuals with advantageous or "adaptive" traits tend to be more successful than their peers reproductively—meaning they contribute more offspring to the succeeding generation than others do. When these traits have a genetic basis, selection can increase the prevalence of those traits, because offspring will inherit those traits from their parents. When selection is intense and persistent, adaptive traits become universal to the population or species, which may then be said to have evolved. Scientists who do experimental genetics employ artificial selection experiments that permit the survival of organisms with user-defined phenotypes. Artificial selection is widely used in the field of microbial genetics, especially molecular cloning.
Whether or not selection takes place depends on the conditions in which the individuals of a species find themselves. Adults, juveniles, embryos, and even eggs and sperm may undergo selection. Factors fostering selection include limits on resources (nourishment, habitat space, mates) and the existence of threats (predators, disease, adverse weather). Biologists often refer to such factors as selective pressures.

Of his London upbringing, Tempah states: “London is one of the only places in the world where you can live in a council block and see a beautiful semi-detached house across the street. Growing up around that was inspirational, it kept me motivated".
In 2006, Tempah gained a great deal of airplay on British music TV channel, Channel AKA, for his song "Tears" He made his first mixtape in 2007 with 28 songs, freestyles and remixes, featuring Mz Bratt, Chipmunk and G-Unit.[citation needed] His first album, Disc-Overy, debuted at number one in October 2010 and was preceded by the number-one singles "Pass Out" and "Written in the Stars" and the UK Top 5 hits "Frisky" and "Miami 2 Ibiza".

You search me - behind of me
Help me - oh, my misery!
Searching son - always on the run
Can't escape - life begins to late
Selected - selected
Trace me - catch me
Kill me - oh, set me free!
Drifting son - believe and ever run
Hiding himself - in a world of emptiness
Exhaust me - love me
Hate me - for my eternity
Now I'm gone - this battle I've won
No more sorrow days - cause you've lost my way
Selected - selected
Searching son - always on the run
Can't escape - this is my fate
Selected - selected
Don't, don't, don't
Don't, don't, don't
Don't do it no more forever
Don't do it, don't do it no more forever!
Selected - selected, forever...
Searching son - always on the run
Can't escape - why have you crossed my way?
Why've you? Why've you? Why've you?
Why have you crossed my way?
Why have you crossed my way?
Don't, don't, don't
Don't, don't, don't
Don't, don't, don't
Don't, don't, don't
