One of compelling evidence of evolution is the bone structure of whale and dolphins. According to theory of evolution, whales evolve from 4 legged land dwelling mammal. https://twitter.com/dummyosi/status/1252434130492481538

As an animal who lives in the ocean, whales and dolphins supposedly does not need bones like the pelvic girdle and the hind limb bones. A close inspection of whales' bone structure reveal that they have both of those things though at a much smaller scale (see the small bone near

-the tail?) Now why would an animal that has no legs, which lives in the ocean at that, has pelvic girdle at all? The evolutionists theorised that those are the remnants or residue of bones from their ancestors which used to walk on land.

Aside from that, the complicated breathing apparatus of whales where it uses its muscle to open and close its blowhole to breathe while in the same time preventing water from entering the hole instead of just having simple gills like fish is also a proof that those animals-

-had gone through evolution and used to live on land and breathe through their nostrils. The bone structure of their flippers are also unmistakably alike to the bone structure of mammalian hands like having carpal, metacarpals, etc.

"If evolution isn't real, and animals are all created by God, why didn't God just create whales with gills? Why bother designing such a complicated way of breathing for these animals while fish's gills work even more efficient (i.e they dont need to go to the surface to breathe)"

That's the argument that evolutionists use against creationists who believes that all living creatures have remain the same way ever since God created them milennias ago. To me personally, this is a very strong argument against the creationist. Because, if evolution isnt real,-

-why do some living creatures (including us) have residual evidence that shows we once evolve from something else? Take our coccyx for example, it's literally called tailbone. I'm sure you can guess why, right?

Take also the example of our vas deferens.

Look at how it takes a long detour from the testes and make a loop pass the bladder before it finally reach its target destination- the urethra. Why is it designed that way? Instead of just having a direct route from the testes to the urethra? The evolutionists theorised it's

-cause our ancestors way back then used to have their testicals way higher up than the position it is in now, which explains the unnecessary loop and detour. If humans are personally designed and created by God, evolutionists argue, it'd make more sense if He makes a direct route

-instead of the current route that the sperm has to take before reaching urethra. Other than that there is also the case of animals having similar bone structures with various species, like bat's wing bones that are identical to human hands, just in different proportion seems to-

-suggest that all living creatures once came from the same ancestors and that evolution is real. There are actually many other compelling and accumulating evidence that prove evolution is real, like DNA, fossil evidence and so on which is impossible to cover in a Twitter thread,

-but you get my point, right? Me personally, I believe in the theory of evolution (because there are just too many evidence to say otherwise) but i believe that evolution is not only driven by natural selection and random mutations, but also through God's Wisdom. Just as various

-raw materials cannot assemble itself to become a sophisticated machine, so does the elements and particles in this universe cant spontaneously give rise to such complex and intricate various of life forms we see all around us. Wallahualam, He knows best.
