Whoever does the mashup for the end-of-year episode, be sure to get the clip of :cara: saying "gimme some MDMA!"

Good episode.

Regarding Ediacaran and Cambrian fauna.  I think the most plausible timeline is that eukaryotes evolved around 2 billion years ago, and multicellular animals evolved around 1 billion years ago, which evolved into the ancestors of Ediacaran and Cambrian phyla.  Both were present in the Precambrian but the Ediacarans were much more common and successful and much more likely to fossilise.

And then the Ediacaran period came to an end with climatic change, the breakup of the then existing supercontinent, massively increased volcanic activity and a mass extinction, including the the Ediacarans.  And the ancestors of the Cambrian phyla underwent an adaptive radiation to fill the now empty ecological niches.

Something similar happened with the K-Pg event.  Mammals were living along with the dinosaurs, but weren’t very successful.  And then the dinosaurs went extinct...

The Cambrian explosion is somewhat an artefact.  Sites such as the Burgess Shale resulted from collapse of cliffs into inlets covering, killing and preserving a whole host of critters allowing a large number of critters to be fossilised (I love the word ‘critter’).  It’s was an explosion of death, not life.

Cara could be right with her citing of 800 mya as the time since the last common ancestors of octopuses and humans, if it’s based based on estimates coming from genetics.  If I’m right, the ancestor must have lived considerably earlier than 560 mya.

Regarding the new book.  Audible recently offered a 3 books for 2 credits special, so one of the books I chose was ‘the Demon Haunted World’ (I’ve previously read it years ago).  It’s absolutely brilliant, even on rereading.  You’ve got a high standard to match.

BTW - the audiobook is also available for pre-order from Audible.com, delivered on the same day.  I checked this morning to find when it was going to available to find that I’ve already pre-ordered it (along with the e-book).

I now christen "Post HoCara Santa Maria" for all the random ideas that she starts giving when she is proved wrong about something. This occurs most frequently during Science or Fiction, when Steve is trying to tell her what the real fact is, but it can also occur naturally in any other segment where she is incorrect about anything.

Sorry Guys, but BST is British Summer Time, which is Greenwich Mean Time, (GMT) +1.

See you all at QED, can't wait...

Is it true that there’s a campaign to dump BST, to go along with Brexit?  In Western Australia there was a campaign once to introduce daylight saving permanently, which was rejected in 4 referenda after trials of it.

I could never see the sense of daylight saving.  You should live your life according to the Sun not the clock.  The silliest thing I think is the leap second which is added on average once every 18 months in order to make noon occur at exactly 12 midday on two days of the year in Greenwich, to avoid the ‘catastrophe’ of noon occurring a few seconds later each decade.

Hi all. I am a fan from India. Is there any reason why the rogues do not mention India often in their conversation? I am clearly biased and I am just curious. Feel free to point out my mistakes.
Cases in point: 1) Discussion on Swastika but no mention of India. (just a small mention of Eastern Asia). 2) Discussion on left and right hand side driving in a previous episode. But no mention of the largest country (by people) who drive on the left side. (I think Australia or Canada was mentioned). Am I missing something? Be kind. :)

My impression is that a lot of people - especially people who aren't from the eastern hemisphere - don't know a lot about India. The exchange of pop culture and media with America particularly is pretty much one-way. The language barrier is only a part of this.

The EU is going to drop the requirement for DST, so it will be up to each country to decide whether to keep it. As it will for the UK outside of the EU. But some might change their time zones to effectively stay on permanent DST.

I agree that a natural time zone would be the better, and even though Norway isn't in the EU, we'll probably drop the biannual change along with them. Hoping that we stick to normal time all year. We never needed DST in summer, and making winter mornings darker can't be good for public health.

The biannual clock change was the thing I disliked most about DST.  The last trial I just refused to alter my clocks (in was before the time when the Internet automatically corrected the time), and mentally corrected the time.

Actually, I liked DST when I was travelling in Europe.  I could do a full day of sightseeing and still get back to my hotel while it was light.

This weeks discussion about mental illness reminded me of a awesome game that I've played... It's called Hellblade: Senua's Sacrifice. This game was very serious about scientific accuracy in terms of what a person with psychotic schizophrenia... they interviewed a lot of specialists in the area and patients who suffer from mental illness... Also, this game had one of the most brilliant plot twists I've ever seen... an incredible exercise of empathy for those who suffer from psychosis ( if nobody spoiled the mechanic for you), something that can only be done in a video game and scientifically speaking, would be impossible in a movie or a book. It also received praise from patients of mental illness around the world! One of the most memorable games I've ever played in my whole life.

I'm very interest to hear the opinion of Cara about this... :)

I think your post here may have had a real effect on Steve.  In his blog today, he posted an article all about India:

Any time steve or Cara talk about fossils, it's obligatory to say "BeYOOtiful" as much as possible.
