What was life really like here on planet Earth before animals were big enough to leave fossils behind? How did living things turn from dinky capsules of genetic material into the intelligent, complex organisms that do things like fart and type curse words into posts on the internet? Scientists think they have found the answer... in algae steroids.

In 1845, Sir John Franklin led two British Royal Navy ships on an ill-fated expedition through the Northwest Passage — a famous and hazardous corridor connecting the Atlantic and Pacific oceans. None of the crew members returned, spawning a mystery that has endured for more than 150 years. A new analysis explores the various ways in which the sailors could have met their demise — including a rare disease historians hadn't considered before.

Palaeontologists uncovered a strange new dinosaur a few years ago — a crazy, patchwork quilt of a creature dubbed Chilesaurus diegosuarezi. Its bizarre and often conflicting characteristics defied classification, forcing scientists to make an educated guess about its place on the dino family tree. New research suggests the initial attempt to classify Chilesaurus was wrong, and that this animal represents an important transitional species within a different group of dinosaurs.

Sea snakes are a striking sight on the sun-dappled Pacific and Indian Ocean coral reefs they call home. They swim with deliberate, yet graceful winding movements above the reef, and they are often conspicuously-coloured, with many species sporting patterns flush with yellows, oranges and blues, broken up by stripes, blotches and spots. This scaly skin, delicately painted by evolution, is part of what makes encounters with them so memorable. However, one species of sea snake — the turtle-headed sea snake (Emydocephalus annulatus) — is losing its captivating stripes. The culprit behind this robbery? Pollution.

The new guy at work invites you over to his house. You feel uneasy. Sure, he's a hard worker, a fast typist, and his intense focus quickly made him an indispensable coworker. But his scarred face seems to betray some violent past. His measured speech seems manufactured. Still, you can't remember the last new friend you made, you have nothing to do, and so you accept the invite.

Nature isn't always sunshine and kitties. This proved itself yet again recently, when researchers at the Universidade Federal Rural do Rio de Janeiro published a study on a pair of conjoined bat twins discovered in southeastern Brazil back in 2001. The animals were dead when they were discovered, which is almost always the case with animals born with a rare condition that results in two heads on a single body.

Sunfish are the living, breathing embodiment of a dad joke — it's kind of funny, but you feel disappointed in yourself for laughing at it because it's painfully silly. Known as the world's largest bony fish, ocean sunfish — which make up the genus mola — look like a drunk person's rendition of a fish, or rather, a person who's never seen a fish's rendition of a fish.

You're probably aware that nature's most badass animal is undoubtedly the tiny tardigrade, or water bear. They might be small, but unlike your weak butt, they can live a life without water, withstand temperatures from -328 to 304 degrees Fahrenheit, and even survive the depths of space. How did evolution make such a strange creature, and who are its relatives?
