Before the discovery of Lucy in 1974, scientists primarily believed that early hominids were more similar to modern humans and that they evolved from a linear progression of species. The prevailing theories suggested that hominids were primarily tool users and had larger brain sizes compared to earlier primates. Lucy's discovery, however, revealed that early hominids like Australopithecus afarensis exhibited a mix of both ape-like and human-like traits, challenging previous notions about the complexity and diversity of hominid evolution. This finding underscored the idea that human evolution was not a straightforward path but rather a branching tree with various adaptations.

What did Mary Leakey's Discovery Of Footprints Indicate About Hominids?
Mary Leakey's discovery of footprints at Laetoli in Tanzania indicated that hominids were walking upright on two feet around 3.6 million years ago. This finding suggested that bipedalism evolved before the use of tools, changing our understanding of human evolution.
Why does the discovery of Lucy and Ardi make many scientists think that humans started in Africa?
The discovery of Lucy (Australopithecus afarensis) and Ardi (Ardipithecus ramidus) provides crucial evidence for the theory that human evolution began in Africa. Both fossils date back several million years and exhibit a mix of human-like and ape-like traits, suggesting a common ancestor for humans and other primates. Their discovery in East Africa aligns with genetic and archaeological evidence, reinforcing the idea that early hominins evolved in this region before migrating to other parts of the world. This supports the "Out of Africa" model of human evolution.
What are two animals unknown to US scientists before 1803?
flying pigs and Worms lots and lots of worms
How do you use yawn in a sentence?
Scientists still do not know why we yawn.Jillian yawned because it was almost midnight.Some people yawn before exercising to get more oxygen into their system.
Why do dogs turn in circles before they defecate?
Scientists believe dogs turn in circles to stomp down grass and weeds to give the dog a place to defecate. Other theories include looking for predators and finding the best place to mark their territories.
Write about the steps scientists follow before they can announce the discovery of new planets describe them in order?
The scientists basically research carry and number of experiments which are later vetted before a discovery is announced.

What of these was not a characteristic of hominids that lived before humans?
One characteristic of hominids that did not exist before humans is the ability to create and use advanced tools. This skill of crafting and utilizing tools is a unique trait that distinguishes humans from other hominids.
What do most scientists believe existed before the incident known as the big theory?
I believe most scientists would agree that this is not currently known. Some, however, would say that there was no "before" - that time itself started with the Big Bang.

Did any hominids exist before the homo sapiens sapiens?
Yes, several species of hominids existed before Homo sapiens sapiens, including Homo neanderthalensis (Neanderthals), Homo erectus, and Homo habilis. These hominids were our evolutionary ancestors and lived at different points in history before the appearance of modern humans.
Who were the scientists who discovered iron?
The discovery of iron dates back to ancient times, so there is no specific scientist associated with its discovery. Iron has been used by humans for thousands of years due to its abundance and utility.
What do most scientists believe existed before the incident known as big bang?
Most scientists believe that an infinite dense singularity existed before the incident known as the Big Bang.
Frederick Griffith made a scientific discovery in 1928. Which best describes the knowledge about genetics before 1928?
Scientists did not know how traits were inherited.
What do Sikhs believe about the big bang theory?
sikhs do believe in the big bang theory. it was written in the guru granth sahib ji before scientists found out.
What continent scientists believe early modern humans came from?
Scientists believe early modern humans originated in Africa. This theory is supported by fossil and genetic evidence that suggests humans evolved in Africa before migrating to other continents.
