Learn 1 /7 Study using Learn
The time it takes for half of a radioactive substance to decay into a stable form.
Example: If the half-life of Carbon-14 is ~5,730 years, then after 1 half-life, only
half of the original C-14 remains.

Relative Fitness The reproductive success of an individual genotype
compared to other genotypes in the population.
, What obstacles are there to passing 1. Survival
on genes? (agents of selection) 2. Reproduction
examples of agents of selection 1. Predators
2. climate
3. disease
4. competition
5. mate availability.
Examples of survival obstacles 1. finding food
2. Predators/parasites
3. environment
4. compete/cooperate with others
5. protection from elements
Examples of Reproduction obstacles 1. Finding a mate
2. energy to reproduce
3. Offspring care
4. compilations
5. defend making territory
Putative adaptation A trait that appears to be an adaptation but needs
testing.
The 4 types of studies 1. Observation Study / Natural Experiment
2. Controlled Experiment
3. Comparative Methods
4. Computer Simulation
Observation Study / Natural ✅ Pro: Can be done on humans
Experiment ❌ Con: Confounding variables
Controlled Experiment ✅ Pro: Controls confounding variables
❌ Con: Limited in human studies
Comparative Methods Comparing species (e.g. bat study).
✅ Pro: Uses data from many species
❌ Con: Less focused on mechanisms
