इतनी विशाल ब्लू व्हेल धरती पर कैसे आई????The evolution of whales from land to sea #shortvideo #ytsho

इतनी विशाल ब्लू व्हेल धरती पर कैसे आई???? Pakicetus was a shore-dwelling creature with webbed feet that lived around 49 million years ago. Scientists were able to link Pakicetus to the evolutionary lineage of whales because of its distinct, dense ear bones. Animals like Pakicetus gave rise to the modern-day giants of the deep. The evolution of whales from land to sea. Around 400 million years ago, the ancestor of all four-limbed creatures took its first steps onto dry land. Fast-forward about 350 million years, and a descendant of these early landlubbers did an about-face: It waded back into the water. Both hippos and whales evolved from four-legged, even-toed, hoofed (ungulate) ancestors that lived on land about 50 million years ago. Modern-day ungulates include hippopotamus, giraffe, deer, pig and cow.
