Wegener's theory of continental drift could not be taken seriously because he did not present it as a proven theory, nor did he have factual evidence that clearly stated why his theory could be true. Scientists can observe these movements using satellite images that show, for example, that the North a. Lesson 1: Earth’s Layers 1. Genetic drift may cause gene variants to disappear completely and thereby reduce genetic variation. Each INB activity is designed to help students compartmentalize information for a greater understanding of the concept. The theory of continental drift was first proposed by Alfred Wegener in 1912.

Continental drift was rejected Continental drift was a good hypothesis that was rejected by other scientists. They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils. But there is a place where sea-floor spreading can be seen on land. When Wegener proposed his idea the lack of a mechanism was the key flaw. For example, let's say that there is an animal that Chapter 6 – Plate Tectonics and Earthquakes If the continents drift, where are we going? I.
