Phylogeny Flashcards
Synapomorphy
a trait shared only
by members of a clade
- An apomorphy shared by multiple,
close relatives.
Nodes
Common ancestor of descendants
Draw a phylogentic tree
Use the example worksheet
Nice
Convergent evolution
same, but independent. Solution for a common problem.
Think about wings and air travel
Evolutionary reversal
Reverting to ancestral state
Homoplasies
make sure to know think. maybe look at a video
Convergent evolution, all moving in the same direction, although appearing to move backwards
Lineage
From root through decendant species
Taxon
Group of species
Clade
All the evolutionary descendants of common ancestor
Comparison of homologous genes can
Reveal evolutionary relationships and conserved adaptaions
Myoglobin
Higher offspirng for oxygen
Regulatory genes with Changing the time and
changing of the structure
Hetrochrony
And can lead to…
Change of timing and how it can lead to profund chnages.
Ex. Giraffe vertebrae
How does phylogentics analysis used for classification and the stdy of life on earth.
Just summarized what you learned
Describe how changes in size and arragnment of genomes can lead to speciation
Rates in functional genes , heterochrony,
