The timeline on this website, The Human Lineage Through Time, added last September, is being expanded. Starting this week and continuing through mid March, we will have an essay for each of the hominin species shown on the timeline. These essays will provide a a wealth of information for students at all levels, discussing how each particular species differes from others on the timeline.
From the Home Page go to The Human Lineage Through Time, observe the evolutionary sweep across seven million years, and click on any icon or binomial. You will see a page of Basic Data on that taxon. Click on the binomial (the two word species name at the top of the page) and you are led to the essay. Several essays will be added each week until all are posted.
Later in the year we plan to add a "photo gallery" to the timeline.
