This week we set about dissecting a Mouse Spider. We have a general look at Tarantulas aka Mygalomorph spiders. We fire up the time machine for a quick look at spider evolution in the Triassic. Harri enjoys the extra oxygen available but decides that the extra size that it gave insects and arachnids might be a worry.
We are back to the old school team of Duncan and Harri this week. We look at Whale evolution, heading back in the time machine to have a look at Pakicetus, Ambulocetus and Remingtonocetus. Harri also hatches a plan to corner the whale milk market, but realises the practicalities of whale milking might prove problematic.
This week we are firing up the time machine and heading back 150 million years to what is now North Africa. Harri has her heart set on riding a Spinosaurus. It has been busy week at SeaDog Vet Services dealing with a crocodile attack and Twit the barking owl, and Xanthe has been making a start on her PADI open water dive ticket. Somehow we manage to morph this into a discussion of Sauropod anatomy.
This week we head back 100 million years to Laramedia and post-mortem a Tyrannosaurus Rex. Harri gets worried about getting home in time for dinner and before 75% of the extant life forms disappeared at the K-T extinction event.
We dust off our time machine to head back 10000 years to visit Beringia. Harri gets a bit freaked out at the thought of Smilodon (Saber-toothed tiger) attack. We discuss the migration of humans to modern day North and South America, Australia and Japan. Xanthe contemplates getting stuck in Beringia and the kind of Hunger Games-esque bow skills that would be required.
This week we indulge in a bit of Q & A about bugs. Somehow we also mention rhinos, body farms, savannahs, edible insects and maggots. Stories via Steve Backshall, Stuff You Should Know Podcast and Entomologist Alex Wild’s www.myrmecos.net
Harri recommends the Body Farm episode of Stuff You Should Know for some gross fun
