 A. All classifications above species is “invented” by researchers who decide how to distinguish between 1 genus and another.

Similar traits often indicates common ancestry Phylogeny (fahy-loj-uh-nee): evolutionary histories of a species Determined by examining: – Fossils –

Warm Up Monday, February 11, 2013 Write out the following analogy with the correct answer attached Mitosis is to Meiosis as… Diploid is to haploid Homozygous is to heterozygous Gentotype is to phenotype

Cladograms

Objectives 1) Determine the common ancestor of a group of organisms by reading a cladogram. 2) List common traits of groups found on a cladogram. 3) Explain how different selection pressures cause a species to evolve.

What is a cladogram? = diagram that show evolutionary relationships btw groups of living things Like a family tree for species

How do you read a cladogram? Closer 2 species are: More closely they are related Have more recent common ancestor May list characteristics that make 2 groups different Everything past this point has 4 limbs.
