The following diagram shows molecular evolution over 55 million years (as represented on the timeline). As we see, the evolution diagram starts with Indohyus, which had dense limb bones, sebaceous glands lost, reduced hair, semiaquatic, and nursed underwater. Then we have Pakicetus, which also had dense ear bones for underwater hearing—followed by Remingtonocetus, which had a carnivorous diet and had a robust tail. Similar to these, we have shown several other animals in this molecular evolution chart. Such charts prove to be a great example to the students studying evolution in general. You can use EdrawMax Online to create other similar evolution charts.
