Changes in allele frequency (control heritable traits) in a population over time - ANSWER ✔✔
microevolution
Accumulation of changes that lead to the formation of a new species - ANSWER ✔✔
Changes in populations from one generation to the next (over time and happens in 1 or more
heritable characteristics) and results in differential survive and reproduction (fitness)-some
individuals have higher fitness than others - ANSWER ✔✔ evolution
All members of a species that live in one area at the same time - ANSWER ✔✔ population
Group of related individuals that share a distinctive form (and are capable of interbreeding- only
applies to sexually reproducing species) - ANSWER ✔✔ species
Put together the theory of evolution along with Alfred Wallace - ANSWER ✔✔ Charles Darwin
Knowledge of evolution at the time that helped lead Darwin to the theory of evolution -
ANSWER ✔✔ species change - Lamarck, mechanism is wrong
From geology - Hutton and Lyel, geological processes have always occurred at similar paces to
current paces; lead to changes in Earth's characteristics
From economics - Mathus, resources are limited, not all members of a population can and will
survive
1. Changes in populations -overtime
2. Proposed a mechanism - natural selection
3. Existing species are derived from preexisting species - today there is evidence for common
ancestry of life - ANSWER ✔✔ theory of evolution
Mechanism of evolution:
1. Variation within a population
2. The variation is heritable
3. A selective process exists (predator, limited resources, illness/pathogen, parasite)
4. Individuals in a population survive and reproduce differentially
5. Change in population occur
6. Lead speciation - ANSWER ✔✔ natural selection
Different types of evidence for evolutionary change - ANSWER ✔✔ fossil record
Biogeography
Convergent traits
