Throughout history, most people believed the Earth to be flat. It wasn't until the ancient Greeks proposed that the Earth was round in the 6th century BC, and this idea gained wider acceptance over time. Today, the spherical shape of the Earth is widely accepted based on scientific evidence.
Most scientists rejected Alfred Wegener's theory of continental drift in the early 20th century because he did not provide a convincing mechanism to explain how continents could move. Additionally, Wegener's idea went against prevailing scientific beliefs at the time, and there was limited geological evidence to support his theory. It wasn't until the development of plate tectonics in the 1960s that Wegener's ideas were widely accepted.
There were two main reasons:Wegener did not propose a plausible mechanism by which continents might move.Wegener was a meterologist, not a geologist, so geologists did not expect him to understand their field.
No, Wegener's theory of continental drift faced significant skepticism and opposition from the scientific community during his time. Many geologists did not accept his idea, as it challenged the prevailing belief in stationary continents. It was not until several decades later, with the discovery of seafloor spreading and the development of plate tectonics theory, that Wegener's ideas gained acceptance and were validated.
The most widely accepted theory among scientists is that the last place humans migrated to was the Americas, crossing the Bering land bridge from Asia between 15,000 and 20,000 years ago.

Most of Darwin's ideas, such as natural selection and common descent, are widely accepted in the scientific community today. However, some aspects of his work, like the mechanisms of heredity and the pace of evolution, have been refined and expanded upon with more recent scientific discoveries.
Theories are ideas accepted as most likely true. Theories are basically hypotheses which have been tested many times by many people and are found to be true.
In science, ideas that are tested through repeated experiments and observations, and are supported by evidence and data, are generally accepted. These ideas are subject to peer review and can be replicated by other scientists.

They were accepted once and at once. They are not accepted now, at least most of his ideas. Freuds ideas, as many ideas in psychology of that day and today, are not supported by evidence but are, seemingly, pulled out of thin air.
