LOOP 3.1: We introduce episode three of Life On Our Planet and discuss one of the most significant stories in the series. We're in agreement that lichens are the unsung heroes of the whole series and that Arthropleura is the crunchiest animal to ever exist. We talk about the ‘fishapod' Strepsodus and its locomotion. Life On Our Planet (LOOP) is a new 8-part series created for Netflix by Silverback Films and Amblin Television. This Steven Spielberg produced series, narrated by Morgan Freeman, is hugely ambitious in its scope, telling the story of life throughout the whole Phanerozoic Eon. Ancient organisms and environments are painstakingly recreated by the supremely talented Industrial Light and Magic, whilst modern natural history scenes add vital context to the story. This show has been worked on for six years, during which time countless papers were read and around 150 different palaeontologists contributed their time and knowledge. The whole production had culture of letting the scientific research dictate scenes, resulting in one of the most accurate on-screen representations of prehistoric life there has ever been. And how do we know all this? Well, our very own team members Tom Fletcher and Dave Marshall have been embedded within the LOOP team since day one! We are therefore in a totally unique position to reveal to you the work that went into this series, from both the production and research side of things. In this unofficial series, we've been granted exclusive access to many of the people responsible for creating LOOP, we explore what it takes to create a palaeontological documentary and we delve deeper into the science with some of the show's academic advisors. Each day, we will be releasing batches of interviews, each relating to a specific episode of LOOP. Image courtesy and copyright of Netflix.
LOOP 3.2: Producer Sophie Lanfear gives us our first insights into how documentaries are shaped. She tells us about the enormous scope of episode three and the difficulty of trying to fit in so many significant events. We analyse her use of emotion throughout the episode and she explains why she opted to use comedy. Finally, we look at the problem of anthropomorphism in documentaries.

Melvyn Bragg and guests discuss one of the greatest changes in the history of life on Earth. Around 400 million years ago some of our ancestors, the fish, started to become a little more like humans. At the swampy margins between land and water, some fish were turning their fins into limbs, their swim bladders into lungs and developed necks and eventually they became tetrapods, the group to which we and all animals with backbones and limbs belong. After millions of years of this transition, these tetrapod descendants of fish were now ready to leave the water for a new life of walking on land, and with that came an explosion in the diversity of life on Earth. The image above is a representation of Tiktaalik Roseae, a fish with some features of a tetrapod but not one yet, based on a fossil collected in the Canadian Arctic.

One of the great themes in palaeobiology is the water-land transition, or how and when the ancestors of today’s four-legged terrestrial animals moved to land. Lines of questioning have included understanding the anatomy and biomechanics of the axial skeleton- head and vertebrae (focusing on biting and swallowing) and the appendicular skeleton (focusing on how the earliest tetrapods walked or swam). Our picture of this story has drastically changed in the last three decades, as new fossils have filled in crucial gaps in the tetrapod evolutionary tree. This changing picture really came to the fore with the work of the late Professor Jenny clack, who’s work at Cambridge in early tetrapods from Greenland and elsewhere brought the water land question back in fashion. Joining us to discuss Jenny Clack's Legacy in this episode are Prof. Mike Coates and Ben Otoo both of the University of Chicago.
Early tetrapods include the earliest animals to grow legs, and their closest ancestors. Moving from the water to land required a number of changes within the skeleton and muscular system, related to moving from swimming to crawling, greater pressure on the body after experiencing further effects of gravity without buoyancy, and the difference in feeding with and without water. This transition is commonly referred to as the 'water-to-land' transition. While a significant amount of work has been done on the anatomical changes through this period, there has been less study on the biomechanics. What has been looked at tends to relate to the mechanical changes related to walking on land and the limbs. However, less has been done looking at the skull mechanics and feeding. Early tetrapod work was pioneered by Professor Jenny Clack. She did a lot of early field work and description, understanding this transition better than anyone. Sadly, Professor Clack passed away in March, but has left behind a legacy of other professors, post docs and students around the globe which she inspired. In this episode, we talk to Dr Laura Porro from University College London about her work on early tetrapod feeding and skull mechanics, and how the skull changed over the water-to-land transition, work which was done with and inspired by Jenny.
In this podcast I have explained clearly and in a detailed way about the tetrapod limb development which is a very important topic for the aspirants of CSIR NET lifescience and other similar biology entrance exams. I have explained about the different elements involved in limb development, three axes of limb development, patterning of forelimb and hindlimb, and introduced the molecular mechanisms controlling these processes. You can solve all CSIR NET lifescience questions based on this topic. If you have any doubt then you can mail me at komaljalan10@gmail.com or biologyatkjc@gmail.com. Your feedback after listening to the podcast will be highly appreciated. --- This episode is sponsored by · Anchor: The easiest way to make a podcast. https://anchor.fm/app --- Send in a voice message: https://anchor.fm/biophilic/message Support this podcast: https://anchor.fm/biophilic/support
Happy New Year! As we transition into a new decade, this episode is about one of the most important and incredible transitions in the evolutionary history of life. In the Late Devonian, one particular group of bony fish spent many millions of years experimenting with new forms of fins, skulls, and lifestyles, ultimately giving rise to the first land-dwelling vertebrates and setting the stage for 300 million years of continental dominance. In the news: the earliest penguins, ancient whale swimming, dinosaur lice, and really old brains.

In this episode I touch on the highlights of your development from a single celled organism to becoming a mammal including the invention of sex, becoming a multicelled organism, moving out of the ocean to wetlands then dry land, the invention of legs, and the displacement of the dinosaurs, with a brief stop to talk about extinction events. All with time for a little banjo break or two.
One of palaeontology‘s great themes of questioning is the rise of novelty: how new structures and functions arise in specific lineages. In this episode we speak with Neil Shubin, Professor of Organismal Biology at the University of Chicago, who has been studying novelty in the context of the vertebrate transition from water to land. Neil studies the fossil record of early tetrapods, the first vertebrates with limbs, to understand what changes underpinned this great transition. The other half his lab uses molecular techniques on living organisms to see how changes to the development of appendages (and their underlying genetic architecture) effected the shift from a fin to a limb. In this interview, we hear about his fieldwork in the Arctic and Antarctic, how palaeontologists decide where to look for key fossils, why development matters, and about his deep involvement in science communication.

The gang spends their 5th anniversary podcast discussing the evolution and distribution of early tetrapods. So basically, we messed up. But at least you can enjoy some insightful discussions about how to improve Sabrina the Teenage Witch. That's something, right? Right? Up-Goer Five (James Edition): The group forget and barely care about their day which comes around every year for five times now. This time they talk about animals with four legs at around the time where they just got out of the water and lived on land before a lot of them died when the things that are not animals and are green and make air went away and everything got less wet. The first paper looks at when these wet areas went away and whether these early animals with four legs ended up with fewer animals that are found over a wider area or lots of animals that are each found in only one area each. It had been though that this change in how much wet made these animals got moved into lots of small areas, but the new paper shows that actually animals with four legs got a lot moved to much wider areas, but that this is because the animals with four legs that lived in water became much less easier to be found while animals with four legs that live on land and have balls that their babies live in early on that don't need water take over and change how animals with four legs lived on the big ball of rock we live on. The second paper looks at where animals with four legs lived before and after the bad time where almost all life died. The paper is interested at whether more animals lived on the middle of the outside of the big ball of rock that we all lived on or whether more of them lived near the top or the bottom of the outside of the big ball of rock. The paper is looking at whether there really is a time where animals with four legs do not live at the middle of the big ball of rock during the bad times where everything was dying. The paper looks at this by seeing how much the rocks lie to us and hide animals that were really there. One way they do this is by looking at tracks as well as dead bodies. This leads to shouting but both people are right and it is okay. The paper shows that while there was some time where there were less animals with four legs in the middle of the big ball of rock, they were still there and so maybe there were just less of them than before but they were not all dead.
