Natural Selection and Evolution
Evolution: the process of species changing over time and it happens mainly through the process of natural selection. Natural Selection: individuals who are best adapted to their environments survive and reproduce the best. Decreases genetic variation. Over time, there will be more of those traits in the population as they survive better and pass their genes on to their children. Adaptation: a trait that helps an organism survive or reproduce in its environment. Gene flow: the exchange of genes between two populations. Increases genetic variation

Explore: 1. How many brown beetles are there? How many green beetles?
2. Describe what you see happening to the beetles? 3. What color beetle would you like to be? Why?
10
Explore: Cont… How many brown beetles are there? How many green beetles? What is happening to the population of beetles?

Explore: Cont… How many brown beetles are there? How many green beetles? Describe what happened to the beetle population over time? What beetle was best suited to survive?
14
Homologous structures are characteristics that have the same basic structure found in different species because they evolved from a common ancestor, not because they serve the same purpose (like the forelimbs above).
15
Analogous structures are structures that serve a similar purpose in two distantly related species.
They are a product of convergent evolution- species becoming more similar over time (example: both butterflies and birds have wings, but they evolved wings independently, not because they are closely related.
16
Because life is so diverse, scientists have created a system for organizing all living things called Taxonomy. The largest taxa (or groups) of living things are called domains. There are only 3 domains— Eukarya (all eukaryotic organisms), Archaea, and Bacteria. The next smaller group is a kingdom. There are 6 kingdoms—Bacteria, Archaea, Plants, Animals, Fungi, and Protists.
17
The full classification system is shown to the right—remember that the best way to remember the order of each taxon is to create a mnemonic for yourself such as. The scientific name for a species consists of its Genus and species.

Phylogenetic Trees show the relationships between different organisms
Phylogenetic Trees show the relationships between different organisms. The different “nodes” (where they come together) represent common ancestors. Some phylogenetic trees are called cladograms and show when traits were gained or lost. Time moves left-->right Phylogenetic Trees Newer Older

Independent Practice Work SILENTLY and INDEPENDLY on questions 1 through 10. If you have any questions raise your hand silently and wait for me to come around. If you are done, raise your hand so I may check your work.
