Final answer:
Hominin evolution trends include the emergence of bipedalism, increased brain complexity, technology and communication, and migration patterns.
Step-by-step explanation:
The trends of hominin evolution represent significant changes in the development of human ancestors and include the transition to bipedalism, increased brain size and complexity, development of technology and communication, and patterns of migration. Over time, these adaptations allowed hominins to better survive and navigate their environments. One of the most distinctive trends was the shift from a quadrupedal to a bipedal locomotion, which is thought to have provided numerous advantages such as energy-efficient movement and the ability to carry tools or offspring. As the genus Homo evolved, these early humans began to migrate out of Africa, leading to the global distribution of modern humans today.
