What calendar did scientists use to outline history of life on earth?
Scientists use the geologic time scale to outline the history of life on Earth. This scale divides Earth's history into different time intervals based on major geological and biological events. It includes periods, epochs, and ages that help scientists understand the timing and sequencing of events in the history of life on our planet.
What are scientists called who study the first humans and early civilizations?

Abundant and diverse fossils first appeared in the Cambrian era, although there is fossil evidence throughout much of the Precambrian.
Which period in the geologic time scale did the penguins first live in?

What Scientists named the first humans Homo habilis which means .?

When did humans get formed on earth?
Humans are believed to have evolved around 200,000 years ago in Africa. The exact timing of when the first human-like species appeared is still an area of active research and debate among scientists studying human origins.
