Silver Screen Science - Jurassic Park (1/5)
Part 1 of 5!
By the end of June, there will be five Jurassic Park films! So for each of the five Saturdays this month, we’re re-watching all of the movies and chatting about the science in a series of “science reviews.” How do these movies handle such subjects as prehistoric creatures, the science of paleontology, and the portrayal of scientists?
This episode, we start at the beginning: Jurassic Park (1993).

Episode 35 - De-extinction
It's time for another extinction episode!
Is extinction truly forever? Could something like Jurassic Park actually be possible? If so, should we do it? As we speak, there are scientists around the world working on the early stages of answering these questions, and in the process developing the very real science of De-extinction.
In the news: sea-going crocs, giant sea snakes, early baleen whales, and super-ancient viruses.

Episode 34 - Ancient DNA
Only a few decades ago, the idea of pulling DNA from long-dead organisms was the stuff of science fiction, but the field of ancient DNA is now totally real and thriving. In this episode, we discuss how we get DNA from ancient specimens and just a bit of the incredible world of information paleogenetics opens up for scientists.
In the news: Another ancient croc-cousin, human and sloth footprints, swimming human evolution, and the oldest wolverine!

Episode 33 - Ontogeny
Animals don’t start their lives as tiny copies of adults; there are all sorts of changes that a creature goes through from fertilization to birth and from newborn to mature. This development is called ontogeny. In this episode, we discuss how ontogenetic change impacts animals as they grow, what we can learn from these patterns, and how ontogeny can cause confusion in the fossil record.
In the news: colorful moth fossils, an enormous ichthyosaur, Neanderthals' strange faces, and sea turtle navigation.

Episode 32 - Naracoorte Caves, Australia
Over the past several hundred thousand years, Australia has witnesed numerous ice age cycles, ecosystems dominated by giant marsupials, the arrival of humans, the extinction of those giant animals, and more. And there may be no better window into this dynamic time period than the world-famous Naracoorte Caves of South Australia.
In the news: an infected dinosaur, humans' earliest steps in Canada, horny dinosaurs, and a four-eyed ancient lizard.

Episode 31 - The Ediacaran Biota
Before life as we know it, and before even the Cambrian Explosion, there was a time when the Earth was home to an assortment of strange squishy creatures so unusual that they defy most of our best attempts at classification. This episode, we discuss life’s earliest experiments with complex bodies: the Ediacaran Biota.
In the news: the last pterosaurs, ancient lost tails, island spider evolution, and the legs of gators and crocs.

Episode 30 - Prehistoric Poop
Everybody poops! Throughout the history of life on Earth, animals of all lifestyles have been littering the planet with little presents, and those few that fossilize become coprolites: unique time capsules that can serve as invaluable sources of information, not just on obvious stuff like ancient diets, but also about evolution, extinction, and more. This episode: we talk turds.
In the news: de-escalating plant evolution, reverse speciation in ravens, upside-down dinosaurs, and record-keeping giant sponges.

Episode 29 - Placoderms, The Armored Fish
In the earliest millennia of vertebrate life on Earth, the seas were home to the placoderms, a diverse group of extinct armored fish whose evolutionary innovations set the stage for some of the most important features of vertebrate life. This episode, we talk about some of history's most influential placoderms, with a special spotlight on the most famous of armored fish, the giant predator Dunkleosteus.
In the news: asteroids and volcanoes, running lizards, Shawn's turtle, walking fish, and more on broken mastodon bones.
