Human Evolution and Biodiversity
Understanding Our Origins and the Diversity of Life

Read MoreHuman Reproduction and Development Stages
Human Reproduction
Females produce female gametes (eggs) and males produce male gametes (sperm). These two cells join to form a zygote.
Internal Fertilization
The egg and sperm unite in the female’s reproductive tract, and the new human being develops there.
Reproduction Steps
- Gamete Production: Specialized reproductive organs produce gametes.
- Fertilization: The union of both gametes inside the female reproductive tract forms the zygote.
- Zygote Development: Within the female reproductive tract, the zygote
