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).
