When studying fossils from different time periods, scientists noticed that the types and numbers of organisms stayed the same for a long time. Suddenly, many new types appeared in the fossil record, showing a quick increase in biodiversity.
This pattern of long stability followed by rapid change is called (a)

To investigate evolutionary relationships, scientists examine the amino acid sequences of a particular protein in sharks and several other marine animals. By comparing these sequences, they aim to determine which species are most closely related to sharks and how their lineages have diverged over time.
Based on the amino acid sequences, which animal is most similar to the shark?
Ray
Salmon
Dolphin
Turtle

On a large island, all the frogs used to breed at the same time and use the same mating calls. Over time, some frogs began calling in a new way, while others started breeding in a different season. Now, frogs only respond to certain calls and breed during their group’s chosen time. As a result, separate groups have formed that rarely mate with each other, even though they live in the same area.
Which type of isolation is mainly causing these frog groups to become separate species?
Geographical Isolation
Behavioral isolation
Temporal isolation
Artificial selection
