Why are there no longer gigantic insects?  Some prehistoric insects could get as large as a meter.  What happened? 

Student Choice Topic Related to Animals or Classification

This week's blog is open to your choice of topic as long as it is related to animals or classification.  For instance, you can research evolutionary lineage, behavior, fossils, etc...

The Importance of Sleep

Research why sleep is so important to health, learning, and memory formation.  Include details and statistics about why you should make it a priority in your daily life.

Neanderthals: Subspecies or Separate Species Than Humans?

What does the current research say about Neanderthals and Homo Sapiens?  Are Neanderthals considered a subspecies of humans, or does science classify them as a separate species.   What does the evidence say?

Mammal Transitionary Fossils

Research what kind of transition fossils exist that shows evidence that mammals evolved from reptilian ancestors.  Include the descriptive evidence that supports this phylogenetic link.

Evolution of the Eye or of Flight

Research how flight evolved.  How many times has it evolved and in what kind of organisms?  What kind of evidence is there?

OR

Research how eyes evolved.  What kind of evidence is there that explains the process of complex eyes being created through natural selection?

DNA and Choromosomal Evidence in Chimps and Humans

What is the evidence that explains how we share a common ancestor with chimpanzees?  There is chromosomal and DNA evidence.  What do these lines of evidence look like?  What is the explanation for how mutations arose to separate our lineages? 

Fossil Evidence for Bacteria

What fossil evidence exists for bacteria?  How do scientists know bacteria existed 3.5 BYA?  (Hint:  look up stromatolites)

Vestigial Structures

What are vestigial structures?  How are they used as evidence that evolution has taken place?  Give several examples of vestigial structures and explain the current and previous function of these structures.
