Explanation:
The initial days and even weeks of pregnancy may happen without a woman being aware of the pregnancy. Even though the baby grows quickly, it starts out as just a fertilized egg. So it takes a while to be noticed. And there is plenty of room at first.
But with an ectopic pregnancy, the baby attaches, instead of in the uterus, outside of the uterus. In most cases, the baby attaches inside the fallopian tube. Outside of the uterus is not designed to provide support and space for the baby. As growth occurs, it can cause severe problems. This is dangerous and can cause bleeding, pain, and possibly shock of the woman's condition is not identified and treated.
Hope this helps! Have an awesome day!! :-)
Answer:
Convergent evolution
Explanation:
Convergent evolution is a type of evolution of similar features and/or structures between organisms that are not phylogenetically related. This type of evolution is known to create analogous structures/organs that exhibit similar or the same functions but were not present in the last common ancestor of these taxa. An example of analogous structures (and therefore also of convergent evolution) are the wings of bats and of insects (e.g., butterflies). Conversely, divergent evolution is a type of evolution where species phylogenetically related, i.e., species that share a common ancestor, evolve and accumulate differences over time.
