Do two slightly different fossils represent an
evolutionary trend? This section of the module addresses this
question by engaging you in an activity where you will be asked to use
prior knowledge from life science and some mathematical knowledge and
skill to develop concepts about variation of characteristics in a
population, evolution--including indicators of past environments and
changes in those environments, the role of climate in biological
adaptation, and use of geological data to examine a data set that might
just document evolution in action. On the menu bar to the left
are two links, the
Field Data
link provides you with a Microsoft Excel file that contains the raw
data used by Kelly in her study of Mollusk Evolution, while the
Learning Activity link provides you
with a downloadable worksheet that asks you to use the information you
have leared in this website, and apply it to outside problems to put
your new found understanding of evolution in to action.
Chose a link on the
left to get
started, or click on the
Change Over
Time: A Virtual Field Study In Evolution link on the menu bar
to return to the main menu.
