The remains of their houses and tombs are scattered throughout the island.Often, sites of this period first become visible through the exposure of middens, the accumulated refuse generated within settlements.

Remains such as those found at Kilellan (Burgess, 1976) and Newton (Mac Cullagh, 1989) indicate that the buildings of this period were rough shelters dug into the sand.

As the climate improved, the fertile lands of Islay attracted the first farmers to come and settle.

This group is dedicated to providing information about the scientific method as it concerns the idea of evolution in the Creation/Evolution debate.

The site provides background information about stratigraphic principles and relative time, biostratigraphy (using fossils for relative dating), and radiometric dating.

The idea of radioactive decay and half lives, a type of absolute dating, is shown through an activity using M&M's candy and graph paper. Sequencing Time, University of California, Berkeley. This 5-12-grade activity lets students place parts of their own life story into a time line so that they can better understand how geologic time is reconstructed by scientists.

Who's on First, University of California, Berkeley. This website is a book chapter about geologic time. This online version of their informative booklet contains short, content explanations about relative time, major geologic time divisions, index fossils for use in age dating, radiometric dating and the age of the earth. These schematic columnar sections contain the stratigraphic sequence for the Transvaal Basin in Africa and the Nabberu Basin and Hamersley Basin in Western Australia.Click to expand a text description Three color coded columns.A few chance finds of bronze artefacts are recorded from Islay, although little is known of the context from which they came.The Iron Age on Islay, extending from the mid first millennium BC to the mid first millennium AD, is poorly researched.The site also provides fact sheets on the age of the Earth and isochron dating.
