BC is also pretty strict. Those who do software development in areas where failure could cause threat to life, health, or the environment are required to be (or overseen by) Professional Engineers, and non-PEngs can't call themselves software engineers. The major universities offer accredited software engineering programs which are separate degrees from computer science, focus less on theory, and include first year sciences and professional ethics courses.

No actually. If you consider the plants to be Archaeplastida (glaucophytes, red algae, and Viridiplantae) or Viridiplantae (the green algae including Embryophyta) then the common plant ancestor is unicellular (greens and reds evolved multicellularity independently). If you consider the plants to just be Embryophyta (the land plants) then they already had highly specialized cells and looked plant-like before they split off from the rest of the green algae.

I'm not sure if the fungal common ancestor is believed to have been unicellular or multicellular but if it was multicellular then it would've been filamentous like modern multicellular fungi, rather than a sheet of cells

Fun fact: Animal embryos can be disassociated by depriving them of calcium (E-cadherin, the molecule that holds the cells together, needs to calcium to work) and then can be allowed to reassociate by adding back calcium. If you do this in early enough stages then the embryo will function and develop normally once reaggregated, despite all the cells being jumbled up

Early animals were likely very similar to Trichoplax, but they weren't Trichoplax. Trichoplax adherins is a modern species with just as many millions of years of evolution between it and the first animal as between us and the first animal. Just bugs me when people end up implying that orthogenisis is real

I think you misread wikipedia when it talks about its endosymbioses. Whole bacteria are found within an organlle (the endoplasmic reticulum) of Trichoplaxs.

That being said what you described does happen in a number of organisms (including 'complex' ones like nudibranchs): they steal the chloroplasts from the algae they eat in a process called kleptoplasty. Seeing as mitochondria and chloroplasts originated as bacterial endosymbionts that were then heavily integrated into their hosts, calling kleptoplasty a form of symbiosis isn't that unusual.

The HBC History Foundation will continue to exist as a non-profit and all the HBC records have been held by the Manitoba Archives since the 70s, so the bit of heritage that actually matters is going to stay.

Not 200 years. The last major direct conflict was the War of 1812 but relations weren't rosy until the Great Rapprochement starting around 1895. The period inbetween saw the Fenian Raids, Patriots' War, Britain's tacit support of the Confederacy and the Trent Affair, and disputes around the Oregon Country and Alaska border. Hell, Confederation happened mostly because of fears of the US's growing power after its civil war.

Tall Boyz: absurdist sketch comedy somewhat evocative of Kids in the Halls (which makes sense Bruce McCulloch was executive producer). Or hell just watch old Kids in the Hall.

Haven't gotten around to seeing it myself but I've heard North of North is pretty good. It's a sitcom set in Nunavut

Das Boot is also really good. A very raw and suspenseful Second World War drama set both in occupied France and inside a German submarine. There's also no "pretend this guy isn't speaking english" thing which is pretty cool. The actors actually speak German when their characters speak German, French when they speak French, etc. So most of the show is subtitled.
