Each Lesson Gets More Fascinating
I was not sold after watching the first lesson. I thought it was going into so much detail that I was going to get lost. But I stuck with it, and by Lesson 3, I was hooked. Dr. Sutherland is whimsical, engaging, and boy, does he know his stuff. There are some rabbit holes he goes down, but this is more than a "surface" overview of paleontology, and I'm grateful for that. And it is entirely relevant today, because of climate events, wildfires, and things that can scare us but that have explanations rooted in history from millions of years ago. If you want to understand what's happening to our planet today, Dr. Sutherland is a great guide.

There is A LOT to learn here!!!
Though this is not a detailed review, I mainly wanted to add my '5 stars' to overall rating. Sutherland is great presenter. He covers many related topics and delivers a very enjoyable & educational course. While I quickly reviewed some of the negative reviews, I respectfully must say that I don't understand their complaints (e.g., boring, too many topics covered, his British accent, a few jokes, etc.). Rather, I strongly recommend this course! It is roughly in the 10%-15% of the +200 courses I have thus far watched.

FINALLY!
DARWINIAN EVOLUTION: Though Darwin’s idea was useful to "get the ball rolling”, the field of “survival of the fittest" as THE driver of evolution has been bothersome for many years. As Sutherland’s course masterfully documents, reality is much more complex. Those of us familiar with complexity theory, (see TGC “Chaos" by Strogatz) have difficulty with “phyletic gradualism” (changes in evolution due solely to Darwin’s ideas) as evolution’s prime mover. Rather, we see multiple causes of DNA change including environmental input (see the Great Course Epigenetics by Mykura) and “random walks" not driven by selective pressure but nonetheless available within existential boundaries. Micropaleontology (the subject of much of this course) is also a player. Lecture 9 (=L9) discusses Hunt’s study of “251 data sets of the morphological characteristics from 53 different evolutionary lineages…” Directional trends (chance and/or Darwinian mechanisms) accounted for a tiny 5%, 45% remained static, and 50% were random (i.e.: non-linear, chaos driven) “random walks”. Thus paleontologically observed “punctuated bursts" of rapid evolution have “just a minor component of…(chance and/or Darwin-style) directed phyletic gradualism”. QED. As Sutherland puts it: “A simplistic (descriptive driven) view of the world will obviously miss the bigger picture."
HIGHLIGHTS: L8’s is a marvelous review of how minerals evolved beyond the 60 expected (after meteors) to 4400 due to everything from tectonics to plants. It might make science fiction writers pause when considering the statistical chances of extending humanity beyond its present confines. L17 shows, in case doubt remains, that the common ancestor of humans did not evolve from chimps. L19 discusses the efficiency of CO2 conserving (and therefore water conserving) pathways of C4 (4-carbon) grasses vs. less efficient metabolic pathways of C3 plants. This chapter will explain why humans could expand and why there was initially concern about the world food supply because of the war in Ukraine. The chapter also includes that mountain up-thrust increased soluble CO2 erosion effects by forming sedimentary clays and decreasing atmospheric CO2. (See also Great Course “Nature of Earth” by Renton L8 if this is unclear).
EXTINCTIONS: This course has a more nuanced view of climate change than most. L14 summarizes the Permian extinction by saying that it had no single cause. While L23 ignores the Novarupta volcanic eruption in Alaska (so powerful it was heard in the Caribbean), Sutherland posits that even the huge 75,000-year-old CO2 spewing Toba eruption may NOT have induced significant climate change as its timing did not correspond with climate change or loss of human populations. This concept is worth following in future courses.
POLITICAL BENEFITS: As certain governmental bodies are now trying to divide our nation into African vs, non-African descent, the reality is that we are all Africans (Lecture L22 = L22). If our society demands black slavery “reparations", L23 suggests a genetic test for anyone with 3% Neanderthal DNA might be a clear dividing line. Unfortunately, TGC’s “African Experience by Vickery" L13-14 demonstrates there were no whites in central Africa to enslave anyone until after the Civil War. Chief Nzinga, later King "Afonso" (not Alfonso), of what is now the Congo was among the first of many West African coast black enslavers. Nzinga nearly emptied out his territory selling his own people for rifles, an African castle, and recognition by a Portuguese King.
CONCLUSION: Early and late in this course, Sutherland refers to the Great Course “Origin and Evolution of Earth" by Robert Hazen. It is one of the most important courses in TGC's repertoire. I'd recommend doing that course first as it provides a background to the mineralogy and earth history of this course. But Sutherland’s course has groundbreaking material, not found in other courses. A Transcript might be more useful than the good 194-page Guidebook in reconstructing the intricacies of Sutherland’s groundbreaking arguments.

Great lecturer but course was a bit disappointing
I bought this course hoping it would give me current, detailed information on life forms that existed previously on our planet. There have been profound discoveries and advances in paleontology over the last few decades in both vertebrate and invertebrate paleontology so I was hoping to be enlightened especially with respect to dinosaurs. I was shocked to find out that there was only one lecture each devoted to dinosaurs and arthropods, two of the most widely and worldly popular fossil groups! So very little on trilobites despite the amazing and important discoveries in Morocco (as well as dinosaur and reptile discoveries there!) and one lecture on dinosaurs that was almost entirely devoted to Spinosaurus with some side notes on dinosaurs in Thailand and Malaysia based on fossil fragments?! The lecture on Spinosaurus was, however, incredibly interesting and it would have been great to hear similar information on other dinosaurs. And I’m sorry, I did not buy a course on paleontology to have one entire lecture devoted to mineral evolution!? Dr Hazen has performed incredible research on this topic but it was totally out of place here! And an entire lecture devoted to grasses?! Coverage of the Devonian and Permian extinctions was good. It essentially ended with a lecture on Neanderthals which I’m sorry belongs in a course on anthropology not to mention they, and Homo sapiens, are only an insignificant blip in the fossil record. The course overview says that it was developed as a partnership with the Smithsonian and how their curators “helped shape the structure and content of the course” then shame on them for omitting so much about dinosaurs (the most successful animals ever on the planet!) along with details on so many other important and interesting fossil groups. Their own Smithsonian magazine recently stated that “there’s never been a better time to be a dinosaur fan” yet only one lecture devoted to them. Dr Sutherland is a great lecturer and really made made this course! He has excellent presentation skills and made all of the lectures worth listening too…even though several lectures/topics were out of place or were of little interest to me. Pretty disappointing overall except for Dr Sutherland.

Paleontology
Well done. Good use of diagrams, charts and graphics. Explanations clear and concise. He is very knowledgeable about his subject matter and presents it well. Did have some difficulty with use of Latin species names that sometimes went on forever. Interesting concepts.

More Than You Need to Know
Be aware that this is a technical approach to the subject as opposed to a “survey course” for general learners. It goes into some detail about mineral formation, the Big Bang, plate tectonics, taxonomy, microfossils, geology, and more. This was a rare occasion when I skipped chapters and didn’t feel guilty. Dr. Sutherland obviously knows his stuff in depth. He uses a chatty, energetic, engaging style. His graphics are many and first-rate. His subject on the face of it is certainly interesting. He gets sidetracked, however, by all the extra alleyways he travels through. Maybe the prof had to stretch to make the presentation into 24 chapters. He wouldn’t be the first to do that. In any event, there is a ton of related but subsidiary information. It’s like asking a carpenter how to drive a nail—who tells you how minerals were formed, how they are mined, techniques of galvanizing, the timeline of square nails in medieval carpentry, and how nails are put to use today. So . . . how do you drive the nail? This course would be quite beneficial to anyone at a university beginning to study paleontology, who needs its web of details. The rest of us must slice through them to find the essence of the course. With that warning, I’d recommend it for listeners who tolerate and respect a rather large web of extraneous facts.

Delightfully Informative
I have had a lifelong "amateur's" interest in paleontology and found this course to be a delight to view. The information was presented in a very organized and easy to understand manner and the visual aids terrific. There was enough depth to the information presented to maintain interest throughout and encourage a desire to delve deeper into specific areas for more details. Well presented throughout.
