Ket [755]

The extinct ancient human Homo erectus is a species of firsts. It was the first of our relatives to have human-like body proportions, with shorter arms and longer legs relative to its torso.

<h3>What are Homo erectus?</h3>

Homo erectus, an extinct species of Pleistocene archaic human, first appeared about 2 million years ago. Several human species, including H. heidelbergensis and H. antecessor, seem to have diverged from H. erectus, with the former being largely accepted as the ancestor of Neanderthals, Denisovans, and modern humans. Among the first recognizable representatives of the genus Homo are its specimens. The first known ancestor of modern humans, H. erectus, had a continental range that stretched from the Iberian Peninsula to Java. H. floresiensis and possibly H. luzonensis may have its origins in Asian populations of Homo erectus. H. erectus soloensis, from Java, dates to a time period between 117,000 and 108,000 years ago.

The old world monkeys characterize for having molars with four cusps joined by ridges. They have bilophodont teeth with better crushing, shearing and wearing capabilities than apes.

The graph models the linear relationship between the water level of the river in feet and number of days the water level measure
galina1969 [7]

Answer:

option 4, y=1/4x+16

Explanation:

to solve this you must find the slope and the y intercept.

slope is rise/run, and equal to 2/8 or 1/4

then, the find the y intercept, find where the line crosses the y axis. Here it is 16.

finally you plug these answers into the slope intercept form, y=mx+b. In this form, m= slope, x=days, and b= y intercept.

after you plug in your answers you are left with y=1/4x+16.
