Wegener first noticed that it looked like South America coastline could "fit" into Africa's. After that he analysed both their continental shelve's and this showed an even closer fit. The thrid observation that brought about his theory of continental drift was that he found fossils of the same animals (can't remember any names off the top of my head sorry) in both Argentina and east Somalia, Africa.
The animal is the Mesosaurus, a fossil known to live 270 million years ago. This animal was very unlikely to swim across the ocean, so the continents had to conjoined one time in the past. Hope this helps :)
Other scientists did not believe Alfred Wegener's hypothesis of continental drift in the early 20th century because he did not provide a plausible mechanism for how continents could move through the oceanic crust. Additionally, Wegener's evidence supporting his idea was largely based on geological and fossil similarities between continents, which were not considered strong enough to support such a revolutionary idea at the time. It wasn't until the mid-20th century, with the development of the theory of plate tectonics, that Wegener's hypothesis gained widespread acceptance.

Alfred Wegener used several pieces of evidence to support his theory of continental drift, including the fit of continents like South America and Africa, similarities in rock formations and fossils across continents, and the matching of ancient climate indicators like glaciation patterns. Despite facing initial skepticism, Wegener's evidence paved the way for the development of the theory of plate tectonics.
The hypothesis of continental drift suggests that continents were once joined together in a single landmass called Pangaea and have since drifted apart to their current positions. This theory was proposed by Alfred Wegener in the early 20th century and is supported by evidence such as matching geological formations, fossils, and the fit of continental coastlines.
Wegener's ideas of continental drift were not immediately accepted by the scientific community because he did not have a satisfactory explanation for the mechanism that could move continents. Additionally, his hypothesis was contrary to the prevailing scientific beliefs at the time, which focused on fixed continents and seafloor spreading. It wasn't until the development of the theory of plate tectonics in the 1960s that Wegener's ideas gained wider acceptance.
The observation that led Alfred Wegener to develop the hypothesis of continental drift was that the continents looked like a puzzle that could fit together and then found out that fossils of similar kind and whats left of similar plants were found on opposite sides of the world.
Nothing.
Alfred Wegener couldn't describe how the plate tectonics moved. So, scientists rejected his hypothesis.
His hypothesis of continental drift
Which type of evidence was NOT used by Alfred Wegener to support his continental drift hypothesis human remains

i am not sure
The main objection to Wegener's hypothesis of continental drift was the lack of a plausible mechanism to explain how continents could move. Wegener's idea of continents plowing through solid oceanic crust was not supported by scientific knowledge at that time, leading many scientists to reject his hypothesis.
The idea known as "Continental Drift."
Fossils, rock layers, and mountain ranges were some of the land features that provided evidence for Wegener's hypothesis of continental drift.
