When Eggs and Sperm Meet
Have you ever wondered why brothers and sisters look similar but not the same? What decides whether one person has their mother’s nose, or their father’s eyebrows?

To begin to answer these questions, and understand what happens when sperm and egg meet, we need to learn a little bit about chromosomes.

But on the inside there are many similarities among human, bird, and bat forearms. Did you know that humans, birds, and bats have the exact same types of bones in their forearm? These organisms share the same forearm bones because they all evolved from a common ancestor.
