Life has a very long history, and we are a very late part of it. You walk through the main events from the first cells to the dinosaurs and the mammals. Then you follow the human line from the early apes to Homo sapiens, with the size of the brain at each step. At the end you read evolutionary trees and the numbers of human evolution with Python. It serves the Indian syllabus (NCERT, NEET) and the matching topic of A-Level, IB and AP.

Life has a very long history, and we are a very late part of it. This lesson walks through the main events that NCERT gives, from the first cells to the age of the mammals, on a strip that you can measure. It also says which parts the NEET syllabus does not list.
We are one branch of a long family line. NCERT follows it from the hairy apes of 15 million years ago to the modern human. This lesson gives each step in turn, with its brain size and what it did, and then follows the numbers.
Two species look alike. Are they close relatives? A tree shows the answer, and numbers can build the tree. This lesson reads evolutionary trees, builds one from a table of differences and uses numbers to date a split.
