Humans mice and giraffes have seven vertebrae in their necks. What can scientists conclude from this observation?

Answer 1

Scientists can conclude that these three species have a similar biological structure and organization, as evidenced by the number of vertebrae in their necks. This similarity may suggest a common evolutionary ancestor or a shared adaptation for their specific lifestyles and environments. Additionally, it may indicate that having a specific number of vertebrae in the neck is advantageous for these species in terms of movement, flexibility, and other physiological functions.
