Earth formed 4.6 billion years ago, and life forms like microscopic organisms appeared 3.7 billion years ago. Prokaryotes and Eukaryotes came into the picture. Various scientists classified them based on their similarities and difference. Lol, I am an armature and not writing a research article here. Recently started reading about the evolution of living organisms.
All these living creatures have got a connection with the water whether it’s plants or animals. According to the evolution of nature, aquatic organisms colonized the land over the years. Similarly from mosses to mango trees, and sponges to humans. Simplicity and simple are the words preferred by everyone, as it sounds simple but it’s not how nature works. These primitive simple organisms were differentiated into complex ones like humans! This is how I believed until I came across this tweet.
I kept wondering how an aquatic animal could evolve from a terrestrial creature. TBH, I was so dumb to believe that whales and dolphins belong to Pisces. I knew something like they give birth to young ones and don’t lay eggs but I didn’t know they belonged to mammals.
Curiosity arouse about how these land animals (Pakicetus) evolved into the “cetacean“? Curiosity stays until a distraction comes right? As usual, I got distracted by some Instagram reels after shallow surfing on google.
I happened to visit one of my senior’s places for some personal work. While chilling, she played a series and storyline focused on a lawyer who suffered from autism. So, it’s a court-seen drama. The main lead adores whales, and whenever she encounters a problem, she refers to the whales to solve it.
I know it’s dramatic but I loved the concept of bringing whales and their unique characters. Curiosity to know more about whales grew stronger and took a few hours to research and write about it too!
Here we go!
The best and most free university that we have now is YouTube and Google.
As I began, It was amazing and surprising to see nature’s mystery. Pakicetus has four limbs, fingers/toes a nostril (Nose to breathe near the mouth), which looks like a wolf or fox, and a tail. They started moving towards the water surface to catch the fish to eat. After some years, there comes an intermediate who can walk and swim, and then came whales.
The whales didn’t have four limbs instead have two flippers to swim. The nostrils went above the head and are called blowholes, and some whales had baleen. It still amazes me! They are magnificent and weigh up to 150 tons (Blue whales).
What is so important for one’s survival?
Okay, oxygen comes before money! We breathe atmospheric oxygen but these aquatic organisms make use of the dissolved oxygen in the water. Their respiratory system is way more efficient than humans. They come to the surface to get oxygen and can survive up to 2 hours in the deep ocean without breathing. Fascinating, isn’t it?
Whales live in communities and the male whales sing to attract their mate. I wonder what lyrics were written in those songs. Do the females conduct singing competitions? Lol, Nature only knows. These songs are helping to do focused work. Give it a try!
Female whales allow only perfect male whales to proceed further. Despite their preferences, they are the best mothers in the ocean. They don’t leave their calf, even lose their weight to feed the younger ones.
They are very passionate and adorable. It gives warmth and felt a little closer to them!
Here are some! Enjoy!
Cheers!
