Idea 1.
Elongated hind limbs, better running, reduced forelimbs
Before dinosauromorphs like Asilisaurus, the evolutionary lineage would include earlier archosaurs. One such early archosaur is Marasuchus lilloensis, which lived around 240 million years ago. Marasuchus exhibits several primitive features that are on the evolutionary path towards dinosaurs.
- Kingdom: Animalia > Phylum: Chordata > Class: Reptilia > Order: Dinosauriformes
- 30 to 40 cm (12 to 16 inches)
- Found in Argentina, South America
- primarily bipedal
- carnivore

Idea 3.
Homo habilis, one of the earliest known human ancestors, emerged around 2.3 million years ago with a brain size significantly larger than modern chimpanzees. By around 1.8 million years ago, they became the first species known to use toothpicks for dental hygiene, alongside their advanced tool use for specific tasks like skinning animals and cutting plants.
