"Past Hiro mistakes Present Hiro for the Future Hiro."

Here's how I think abilities are triggered.
In times of emotional stress or times of fear, an evolved human will develop an ability to help them in such a situation.
Examples
Nathan with his flight during the car crash; Becky and her invisibility when trying to hide from Noah; Maya's poison emission when she wanted to hurt people; Stephen Canfield when he wanted his neighbour to go away; Linderman's healing when he wanted to heal his mother's cancer; DL's phasing when he wanted to escape prison; Claire's RCR after hurting her hand; Rachel's teleportation when she needed to escape a falling beam; Donna Dunlap's telescopic vision when trying to read in the dark as a child.
For those whose abilities develop during an eclipse and other times, their ability developed reflects their personalities and their wants and daily needs.
Examples
Peter Petrelli wanted to emotionally help people, and developed empathic mimicry; Charlie Andrews was a waitress and was always taking note of orders, so her ability developed as enhanced memory; Niki Sanders wanted the strength to look after her son; Emma Coolidge is deaf and her ability first manifested as being able to see sounds; Arthur Petrelli always wanted to be the one in power, so he steals others' abilities; Santiago wanted to know where his life was going; Bob seems to be well educated and enjoy finer things in life, much like a rich person; Elle's personality could be described as shocking; Joseph wanted to keep his brother calm; Tracy was known as the ice queen because of her cold personality; Candice wanted to look different and wanted others to look different; Joe Macon's job was to write on a lot of paper, imprinting was useful for his job; Sylar was a watchmaker and his intuitive aptitude helped him understand their workings; Sue Landers worked in an office, lie detection would have helped her pick out liars in her office; Eric Doyle always wanted to be in control; James Martin wanted to be someone else; Hiro Nakamura wanted time to pass, so he gained STM; Daphne Millbrook couldn't walk, then was able to run with no problems; Matt Parkman wanted to know what others thought about him, and got telepathy; Alex Woolsly was a swimmer who developed underwater breathing.
