When pondering the inhabitability of planets for advanced life, we need to consider planetary evolution and how it changes the weather and surface environments of the planets. The first question is: how much water was available to these planets when they formed? Our terrestrial planets may have been irrigated by asteroids slingshot toward the inner solar system by Jupiter's gravity.

But what happens in systems without Jupiters? A 2010 study by Rebecca Martin of the University of Colorado reported that only a tiny fraction of planetary systems observed to date seem to have giant planets in the right location to produce an asteroid belt of the appropriate size to influence inner planets. If it's more massive the planets are rototilled by frequent asteroid hits - and this might not be good for biological evolution.
Another study by Martin found that our terrestrial planets formed from rocky debris in a dry, hotter region, far inside of the solar system's so-called "snow line." The snow line currently lies in the middle of the asteroid belt. Beyond this point the sun's light is too weak to melt the icy debris left over from the protoplanetary disk. Conditions within disks will vary from star to star and so the solar system's comparative dryness cannot give us insights into Kepler-62.
Compounding the astrobiology question is the fact that Earth's own evolution shows how a planet even in the habitable zone can dramatically change over time. Four billion years ago Earth had a thick carbon dioxide atmosphere and green oceans full of iron. At 700 million years ago Earth was entombed in ice because of runaway glaciation triggered by changes in ocean currents caused by the appearance of a super-continent. Earth has only had a rich surface biosphere for the past 500 million years.

Therefore, planetary evolution keeps shuffling the playing deck. The inner planet, Kepler-62e, may really be a super-Venus rather than super-Earth. It would be a hellish place with a chocking carbon dioxide atmosphere and continuous volcanism. One the other hand could "Venus be just a fluke?" speculated one Kepler scientist.
