Study Notes
Types of Parasites
- Social/brood parasites exploit the social behavior of their host, e.g., cuckoo birds laying eggs in other birds' nests.
- Kleptoparasites steal food or resources from their host, e.g., some bird species stealing food from other birds.
- Hemiparasites obtain some nutrients from a host plant but can also photosynthesize and produce their own food.
Life Cycle
- A specific sequence in an organism's development, beginning with gestation and ending with death.
- Life cycles can be divided into two major stages: growth and reproduction.
Mimicry
- An evolutionary adaptation where a weak organism mimics features of a strong organism for protection.
Metamorphosis
- A biological process where an animal undergoes a significant change in body structure after birth or hatching.
- There are two types of metamorphosis: complete and incomplete.
- Complete metamorphosis occurs through four stages: egg, larva, pupa, and adult.
- Incomplete metamorphosis occurs through three stages: egg, nymph, and adult.
Life History Strategies
- The way an organism divides its resources and energy between survival and growth, and reproduction.
- Life history characteristics affect the survival, mortality, and reproduction of a species (e.g., birth rates, age at first reproduction, number of offspring, and death rates).
Selection and Variation
- Genetic variation occurs within a population and can be inherited.
- Overproduction of offspring leads to competition for survival.
- Individuals with beneficial adaptations are more likely to survive and pass on their genes.
- Over many generations, there is a change in allele frequency (evolution).
Levels of Selection
- Gene-level selection: the unit of selection is the individual gene.
- Individual selection: operates at the level of the individual organism and selects for traits that increase an individual's fitness or reproductive success.
Types of Genetic Drift
- Bottleneck: a population's size becomes very small due to a catastrophic event, leading to a loss of genetic variation.
Big Bang Theory
- Three evidences: Hubble or cosmic expansion, cosmic microwave background, and primordial or big bang nucleosynthesis (BBN).
- Inflation epoch: the universe expanded rapidly and cooled, leading to rapid expansion and cooling.
Earth's Structure
- Outer core: responsible for the Earth's magnetic field, composed of liquid iron and nickel, and has a low viscosity.
