Evolution, Classification, and Genetics
29 cards
Card 1
Question: What is the basic idea of evolution as described here?
Answer: Species change over time, adapting to their environments through genetic variation and natural selection.
Card 2
Question: According to Lamarck’s theory of use and disuse, how do organisms acquire traits?
Answer: Organisms acquire traits during their lifetime (e.g., stretching) and pass them to offspring — an idea modern science has disproven.
Card 3
Question: What are the key ideas of Darwin’s theory of natural selection?
Answer: Variation exists within populations; individuals with advantageous traits are more likely to survive and reproduce, and evolution acts on populations,
Card 4
Question: What does the Neo-Darwinism (Modern Synthesis) combine?
Answer: It combines Darwin’s natural selection with genetics: mutations create variation and natural selection determines which traits persist.
Card 5
Question: Give one application of evolutionary theory to medicine.
Answer: Explains antibiotic resistance in bacteria.
Card 6
Question: Give one example of how evolution predicts responses to climate change.
Answer: Species may develop traits suited to new conditions — example: Mexican kit fox with large ears adapted to heat.
Card 7
Question: What metaphor describes the relatedness of all organisms mentioned in the content?
Answer: The "Tree of Life" connects all organisms through common ancestry.
Card 8
Question: What is a domain in biological classification?
Answer: The highest taxonomic rank.
Card 9
Question: What are Archaea and how are they characterized in the content?
Answer: Archaea are extremophile prokaryotes with unique cell walls.
Card 10
Question: How were Archaea and Bacteria described in relation to cellular organization?
Answer: Both are prokaryotic kingdoms (groups of prokaryotes).
