DARWIN PRESENTS HIS CASE Big Q Under what
DARWIN PRESENTS HIS CASE Big Q: Under what conditions does natural selection occur? Big Q: What does Darwin’s mechanism for evolution suggest about living and extinct species? Big Q: What do homologous structures and similarities in embryonic development suggest about the process of evolutionary change”
ENGAGE - COMPARING BONES ➤ Investigate the similarities and differences between the forelimb of a cat and a lizard ➤ ***Answer all questions on your Inquiry Warm-Up Worksheet
EXPLAIN - DARWIN’S FINDINGS ➤ Natural Selection - organisms with variations most suited to their local environment survive and procreate ➤ Variation differences in heritable traits ➤ Adaptation characteristics that increase survivability ➤ Survival of the Fittest ➤ how well an organism can survive and reproduce Fitness traits that describe how well a species can survive
EXPLAIN - COMMON DESCENT ➤ Common Ancestor - all species, living and extinct, descended from a common ancestor Phylogenetic Tree - shows ancestral relationship
ELABORATE - BIRDS OF A FEATHER ➤ Investigate local animals and suggest common ancestors ➤ ***Answer questions on your Inquiry Warm-Up Worksheet
EXPLAIN - BIOGEOGRAPHY ➤ Biogeography - study of where organisms live now and where their ancestors lived in the past ➤ Darwin studied fossil records to support this study Identify possible advantages of specific changes
EXPLAIN - COMPARATIVE ANALOGY ➤ Homologous Structures similar structure, different function ➤ Analogous Structures different structure, similar function ➤ Vestigial Structures structures that no longer function
EXPLAIN - COMPARATIVE ANATOMY ➤ Embryology - similar patterns in embryological development suggest common descent ➤ Molecular Biology - genetic code and homologous molecules provide evidence of common descent
ELABORATE - MOLECULAR HOMOLOGY IN the HOXC 8 ➤ Analyze the data from Hoxc 8 gene in different species ➤ **Answer questions on your worksheet
