PPT-Evidence of Evolution Taylor Zewe, Brooke Loomis, Allison Linton

Pd2 Anatomy and Physiology Evidence for evolution can come in the form of anatomy and physiology For example vestigial analogous and homologous structures Vestigial Structure The concept of vestigiality applies to genetically determined structures or attributes that have apparently lost most or all of their ancestral function in a given species An example is the human appendix. www.linton.info e-mail lneditor@linton.infoVol. 28 NOver 2,350 copies free in Linton, Too good for jumble...THE following items are all for sale: the dismantled shed in Balsham – 6ft x 4ft appro Variation in Living Things.
