There is no force more creative than the painstakingly slow process of evolution. Ever wanted to walk through walls? Naked mole rats can physically bore through concrete. How about fly? There are a couple dozen different ways to accomplish that goal, even if you’re a squid. Incredible power of regeneration? Flatworms, roundworms, and echinoderms have us beat. Among the vertebrates, species like the axolotl can regrow limbs, organs, and parts of their brain. For practically every super power we can imagine, something on the tree of life has come up with a real-world analog.
Some real super power are more super than others:
1. The immortal rotifer that absorbs the abilities of anything it touches.
Around 80 million years ago, a small, unassuming group of metazoa decided that sex just wasn’t for them. Instead of going through the effort of recombining their genetic material with a mate every generation to produce a viable offspring with a roughly 50% contribution from each parent, Bdelloid Rotifers started reproducing asexually. Males completely disappeared from class bdelloidea, leaving females to generate genetic duplicates through parthenogenesis. This is not their super power.
Bdelloid rotifers are incredibly tough. When environmental conditions are less than favorable, they can enter a dormant state. In this dormant state,they can survive the worst unscathed. Dehydrated, they can endure extreme temperatures, drought, even ionizing radiation. A bdelloid rotifer in its dormant state can even survive in space. If that isn’t enough, while dormant, these rotifers continue to produce offspring, which also remain dormant. This is not their super power.
Bdelloid rotifers’ super power appears when they recover from their dormant state. As they rehydrate and repair whatever damage their cells incurred, they incorporate DNA fragments from their environment. This includes partially digested food and any DNA in close proximity to them, even bacterial and archael DNA. It is this ability that allows bdelloid rotifers to overcome the limitations of asexual reproduction and survive for 80 million years without mates. They can literally absorb the attributes of those around them.
Their incredible toughness, celibate lifestyle, and ability to absorb the powers of anything they touch, put Bdelloid Rotifers firmly on par with X-Men perennial favorite: Rogue.

Originally published on August 30th, 2011, Climbing Mount Chernobyl is one of my personal favorite posts. It feels appropriate to re-post it today for World Ocean Day.

In the last century, humans have made dramatic changes to both local and global ecosystems. Some of these changes have been subtle and remained unnoticed until very recently, while others were so visible and so destructive that their names are indelibly etched into our collective consciousness. Despite a legacy of desolation, many of these places, unsafe and long-abandoned, have made dramatic recoveries. Standing tall, but not alone, among these environmental catastrophes is the melt-down of reactor 4 at the Chernobyl Nuclear Power Plant.
