Evolution Quote by Bill Nye
““Once an egg has been fertilized and managed to attach itself to the wall of the uterus and gastrulates (produces the three layers), the next key stage is the development of the “blastocyst,” the sack or sphere of just one hundred fifty cells that is produced by the first few divisions of the single cell that is the fertilized ovum. These cells will divide and divide to become a porpoise, a possum, or a person.””

Embryonic development proceeds from fertilized egg to blastocyst, a stage where cells multiply before differentiating into diverse organisms.
In simple terms: Early cells multiply before becoming specific animals.

Questions to Reflect On
- How does early cellular environment influence later traits?
- What ethical considerations arise from manipulating early embryos?
A Different Perspective
Complex genetics and environmental factors also shape outcomes, not just early cell count.
