Charles Darwin encountered a tiny fox-like creature during his famous voyage but instead of discovering its fascinating evolutionary story, he just knocked it on the head with his geology hammer.
Thanks as always to Julio Lacerda ( / juliotheartist ) for the tremendous reconstruction of Darwin's Fox!

And the sad part is, Darwin sat on his discovery for 20 years out of fear religious thugs attacking him (and it really happened, Darwin was verbally assaulted dozens if not hundreds of times and his theory was rabidly torn apart, but he was lucky a few young atheist biologists like Thomas Henry Huxley adopted his thinking as it was based on prof, not stone age voodoo, and started vigorously fighting back, or the theory of evolution would be buried and forgotten for the next century)...

@@KuK137 Darwin also experimented with the sea iguanas of the Galapagos by throwing them in the water and watching them swim back to land, where he caught them and threw them back. He was demonstrating that these creatures instinct said that they were safer on land when in danger, even if the danger was a lizard-throwing naturalist. Probably fun for Darwin, and non-lethal for the iguana.

It's so interesting to see how a natural corridor allowed canids to find these ecological opportunities and expand their territory. Ironically, now, we have to create corridors like this one to save species. Our crew recently filmed a project that aims to create a jaguar corridor through south and central America to save the species. Jaguars lost 50% of their natural habitat, which makes it harder for them to find each other and reproduce. Travelling wouldn't be a problem for them, but the territory they have to cross to reach protected areas are roads, and croplands, making everything extremely dangerous for them. On the positive side, the project is already showing promising results.

Yes indeed. Florida also is creating natural corridors to help the florida Panther rebound back from the bring of extinction. Originally they roamed all of the SE USA. But now there are only 250 left with only breeding population in SW florida. Hopefully they allow these bills to pass to protect the Florida Panther; bc there’s only so many pieces of unspoiled paradise left.

@runenorderhaug7646 Жыл бұрын

Technically evolution to some level was being worked on before. What Darwin really started is realizing how much of the process tied into natural selection rather than being solely based on something like lamarkian evolution. While things like epigenetics have brought up aspects of those periods in super specific areas, this realisation around natural selection was what truely ended up creating modern biology

I am a Palaeolithic archaeogist. My kids, like so many, are obsessed with ancient animals and evolution. This PBS series is extremely praisewothy as it does not only explain why happened in the past and why, but it also explains the epistomology of the disciplines that investigate the past and teaches children (and adults!) how we know what we know and why we conclude it is true. So we learn about theories of knowledge and how to apply them. Unfortubately, this is something not adequately taught --if it is taught at all -- in most of our public schools where children are not encouraged to question and explore, but rather are rewarded for demonstrating their indoctrination into unchallenged "systems of belief" reinforced by rote memorization. Thus we have a population that accepts without question what they have been told most loudly and with most repetition, and is suspicious even antagonistic to scientific inquiry.

@probablygeorge6489 Жыл бұрын

I mean you can thank religion for normalizing childhood indoctrination and brainwashing. I mean religion in of itself is antagonistic to scientific inquiry as where science is willing to say "I don't know, let me put together falsifiable hypotheses and test them until I come upon one I cannot disprove" while religion asserts "this is true, this is fact." Usually without explanation.
