The final episode explores dinosaurs' extraordinary ability to survive. Featured dinosaurs include the bizarre magyarosaurus, which lived in the shadow of the biggest flying animal - hatzegopteryx - and showed an amazing adaptation to island life; and the weird nothronychus, a carnivore that gave up meat eating. This astonishing capacity to evolve into ever more diverse and bizarre forms meant that dinosaurs not only spread throughout the world, but also dominated life upon it for more than 160 million years. It was only an unprecedented extraterrestrial event that finally saw the end of planet dinosaur.

Ripped from international headlines, The Hacker Wars takes you to the front lines of the high-stakes battle over the fate of the Internet, freedom and privacy". Get ready to be shuttled between story lines at lightning speed mirroring the disjointed lives of the protagonists and life on the Internet. The Hacker Wars- a film about the targeting of (h)ac(k)tivists and journalists by the US government. Hacktivists are either terrorists or freedom fighters depending on ones perspective on who should control information. Meet weev, infamous hacker; Barrett Brown, journalist and propagandist for the hacktivist collective, Anonymous; and Jeremy Hammond, aka Anarchaos, number one on the FBI's cyber-criminal list. The fourth character is Sabu, the uber-hacker turned FBI informant who ran the FBI's cyber unit for 9 months and is responsible for many arrests. He is the shadowy protagonist in a high-stakes game of espionage and betrayal in the age of the Internet. Barrett Brown, American journalist, is facing 105 years in prison for publicizing information revealed through Jeremy Hammond's epic hacks. Hammond himself has just begun a 10-year prison term. Andrew Auernheimer, known by his hacker handle weev embarrasses large corporations. He was sentenced to 41 months for hacking AT&T, but his conviction was just overturned. He vows to continue doing what landed him in prison in the first place. These hacktivists are the rock stars of the Internetmodern-day folk heroes. Glenn Greenwald (Snowdon Leaks), Pulitzer Prize-winning journalist and others explain why these anti-heroes exposing the security surveillance state are essential to a functioning democracy.

To survive, animals need somewhere to live, a place that provides the necessities of life, shelter from the elements and a refuge from enemies. Good homes are rare and competition can be intense – finding a home is one thing, but defending it is quite another.

This episode covers the nature of how life may have developed on Earth and the possibility of life on other planets. Tyson begins by explaining how the human development of writing systems enabled the transfer of information through generations, describing how Princess Enheduanna ca. 2280 BCE would be one of the first to sign her name to her works, and how Gilgamesh collected stories, including that of Utnapishtim documenting a great flood comparable to the story of Noah's Ark. Tyson explains how DNA similarly records information to propagate life, and postulates theories of how DNA originated on Earth, including evolution from a shallow tide pool, or from the ejecta of meteor collisions from other planets. In the latter case, Tyson explains how comparing the composition of the Nakhla meteorite in 1911 to results collected by the Viking program demonstrated that material from Mars could transit to Earth, and the ability of some microbes to survive the harsh conditions of space. With the motions of solar systems through the galaxy over billions of years, life could conceivably propagate from planet to planet in the same manner. Tyson then moves on to consider if life on other planets could exist. He explains how Project Diana performed in the 1960s showed that radio waves are able to travel in space, and that all of humanity's broadcast signals continue to radiate into space from our planet. Tyson notes that projects have since looked for similar signals potentially emanating from other solar systems. Tyson then explains that the development and lifespan of extraterrestrial civilizations must be considered for such detection to be realized. He notes that civilizations can be wiped out by cosmic events like supernovae, natural disasters such as the Toba disaster, or even self-destruct through war or other means, making probability estimates difficult. Tyson describes how elliptical galaxies, in which some of the oldest red dwarf stars exist, would offer the best chance of finding established civilizations. Tyson concludes that human intelligence properly applied should allow our species to avoid such disasters and enable us to migrate beyond the Earth before the Sun's eventual transformation into a red giant.

The next instalment focuses on dietary needs and how different species have evolved beaks to suit their individual requirements. The latter come in a multitude of forms. Blue tits and goldfinches have beaks akin to tweezers, with which to extract seeds, while the hawfinch's razor-like bill can deal with a cherry-stone. However, the crossbill is the only finch that can twist its mandibles in opposite directions. Jays store acorns for winter by burying them in the ground, whereas woodpeckers can keep up to 60,000 of them in one tree trunk. Sap is also desirable, and there are a variety of methods used to obtain it. The hoatzin is the only specialised leaf-eater, and accordingly has a digestive system more akin to that of cattle. Plants recruit birds to aid pollination, and offer nectar as a reward. Hummingbirds eat little else, and the sword-bill's beak is the longest of any bird in relation to its body. Insects are also highly prized, and Galapagos finches are shown to possess some ingenuity as they not only strip bark, but also use 'tools' to reach their prey. Crows are hailed as being among the most intelligent birds, and one is shown using a twig to spear a grub within a fallen log. The robin is an opportunist, and Sir Attenborough observes one seizing morsels as he digs a patch of earth. In South America, a cattle tyrant sits atop an obliging capybara and uses its vantage point to spot passing food that may be dislodged by its grazing partner.

This completed featured documentary series reveals long-buried information discovered during the filmmakers' seven-year investigation of a series of unsolved crimes, and the man suspected of being at its center – Robert Durst, scion of New York’s billionaire Durst family – and was made with his full cooperation. 'The Jinx' expose police files, key witnesses, never-before-seen footage, private prison recordings, and thousands of pages of formerly hidden documents. Directed and produced by Andrew Jarecki and produced and shot by Marc Smerling.
