Cats That Act Like Dogs: The Science Behind Copycat Evolution
Copycat Evolution: How Cats and Dogs Surprised Scientists with Parallel Adaptations? Scientists discovered that flat-faced cats and dogs evolved similar features independently – a Purrfect example of ‘copycat’ evolution! In Bern, Switzerland, an unusual museum collection holds the largest scientific assembly of pedigree dog skulls in the world 2,800 specimens representing more than…

Crocodile Evolution’s Winning Formula
The Secret to Crocodilian Survival Crocodiles and alligators – ancient creatures that seem to have stepped directly out of the Jurassic era. While many of their relatives have vanished, these remarkable reptiles have persisted, defying extinction. What’s their secret? A recent study showed that their extraordinary longevity is deeply rooted in their incredibly flexible lifestyles.…

Why Horses Are Naturally Built for Speed
For over 5,000 years until about 150 years ago horses were essential to human life. Their incredible strength and speed made them perfect for hard labor, travel, and racing. This athletic ability comes from their muscles, which are packed with mitochondria (the cell’s energy factories), allowing them to use oxygen efficiently. Through evolution, horses…

Intertwined sheep and humans over millennia
Coevolution of sheep and humans over millennia(10,000 years old period). By studying ancient DNA, we have found that sheep and humans have been co-evolved. Biology of sheep has an important role in shaping the human civilization. It has helped explain, the human history, culture and survival. Different international research teams from different academic backgrounds including…

Archaic Hominin Admixture
Archaic Hominin Admixture: Paleogenomic studies have found that modern humans interbred with Neanderthals and Denisovans, and that some of us carry DNA from these archaic hominins. Among the discoveries of Paleogenomics, is the evidence of interbreeding between modern humans and archaic hominins like Neanderthals and Denisovans. These are extinct human relatives who lived alongside or before early…

aDNA vs Modern
Ancient DNA (aDNA) and modern DNA differ in many aspects due to the degradation processes that aDNA undergoes over time. We can compare on the bases of Integrity, modern DNA, Typically, well-preserved and intact, existing as long, continuous strands. Ancient DNA, Highly fragmented due to chemical and physical degradation (e.g., exposure to oxygen, water, temperature…

Computational evolution
Computational evolution is a interesting field that uses computational methods to study and simulate evolutionary processes. It draws inspiration from biological evolution, employing concepts like natural selection, mutation, recombination, and genetic drift to solve problems and understand complex systems. Evolutionary Algorithms: These are a family of algorithms inspired by biological evolution, used for optimization and…
