yes they evolved from the trilobites
Birds evolved from small reptiles that lived during the age of dinosaurs, but not from the dinosaurs themselves.
Rhinos first appeared around 50 million years ago during the Eocene epoch. They evolved from smaller ancestors and have undergone significant adaptations over time to become the animals we recognize today.
Mammals evolved adaptations that allowed them to live on land, in the air, and in the water during the Cenozoic Era. The Cenozoic Era began approximately 65 million years ago.
The Tertiary period happened after the extinction that took place during the Cretaceous period, so mammals saw a great diversification, the most notable of which was the movement from eating from trees to eating grass. Along with these mammals, birds also became the dominant animals in land ecosystems.
Why do you think our ancestors have riddles during the early period?
Echinoderms are thought to have evolved from bilaterally symmetrical ancestors because their larval forms exhibit bilateral symmetry. Over time, echinoderms undergo a process called pentaradial symmetry, where they develop a five-point radial symmetry characteristic of adult echinoderms. This suggests a modification from bilateral to radial symmetry during evolution.
The elephant
No: Cenozoic. (Tertiary).
Yes there was music during the ancestors time. But the music is produced by their own bare hands on handmade instruments.
Spears, hatchets and rocks.
Because their ancestors lived in a colder climate than most buffalo species (except the American and Wood Bison). They evolved to be able to grow thick coats during the winter, then shed them for summer.
