Document Summary

Chapter 19: species and speciation i and ii. If there are actually (evolutionary independent) 9 subspecies, then some of these subspecies are actually critically endangered. There should be no gene flow because that ensures that: each group has its own genetic distinctness and its own evolutionary trajectories. This will allow them to stay separate species: however, gene flow keeps allele frequency. similar among populations and keeps species cohesive (similar traits, new traits spread among populations, morphological sc. Individuals of one species share measurable traits that distinguish them from other individuals from other species: the traits do not have to be morphological -> can be physiological, genetic, etc. They: are unable to interbreed successfully, have distinct morphological characteristics. Lecture 12: form independent branches on a phylogenetic tree. How do we have 23 pairs and chimpanzees have 24: hypothesis: chromosome fusion event, conservation of order of homologous genes, conserved structure (centromere, ex.
