Study Notes
Life Cycle Comparison
- All species on Earth have descended from the same simple organism and have evolved differently along the tree of life.
- The differences between species can be seen in their life cycles, including reproduction, lifespan, and development.
Reproduction
- Mammals produce live young, while insects, birds, and amphibians lay eggs.
- The gestation period for mammals ranges from 12 days to 95 weeks.
Lifespan
- The shortest-lived species are mayflies, which can live from 5 minutes to 24 hours.
- The longest-lived species are bowhead whales, which can live up to 200 years.
- Other species with notable lifespans include the termite queen (50 years), Laysan albatross (47 years), and cave salamanders (100 years).
Development
- Mammals are born fully formed, while insects and amphibians undergo metamorphosis from larvae to adult.
- Birds are also born fully formed, but may take time to develop fully.
Parenting
- Mammals nurture their young for varying periods, from a few weeks to many years.
- Insects do not provide parental care, while birds and amphibians care for their young for a short period.
Diet
- The diet of young mammals is the same as their mothers' milk, while young insects and amphibians have different diets than their adults.
- Tadpoles, the young of amphibians, eat plants, whereas adult amphibians are carnivores.
