Chickens have 78 chromosomes. There is nothing incremental about moving from 76 to 78. Or, from 78 to 80 (turkeys).

- drewbug 7y agoHow is incrementing by 2 not incremental?
- lurquer 7y agoIt's discontinuous. It's obvious what the post implied... that the changes are gradual and continuous.

- Tagbert 7y agoEvolution is a feature of populations, not individuals. If the proto-chickens had 76 chromosomes, and some had a tendency to have offspring with 78 chromosomes, there would be some 78 chromosome chickens born within the population. As long as those chickens bred with each other it would work. Soon they would become a distinct population of individuals breeding with each other.
- lurquer 7y agoHow often do chicken have offspring with an extra pair of chromosomes? Do you have data on this?
