<h2>The given statement is true</h2>
Explanation:
The recent finding of the fossils which showed that <em>Homo erectus</em> and <em>Homo habilis</em> lived side by side in eastern Africa for perhaps half a million years challenged the conventional way that these two species evolved one after the other(<em>H.habilis</em> 1.44 million years old and <em>H.erectus </em>1.55 million years old)
- The fossils were found in Kenya and took years to prepare the specimens for study and to be sure of the identification of the species, the scientists said
- University of Utah geologists determined the dates of the fossils from volcanic ash deposits
- The most recent <em>Homo habilis</em> that had been known was about the same age as the earliest <em>Homo erectus</em><em>,</em> said Daniel Lieberman, a professor of biological anthropology at Harvard University, “Now we have extended the duration of the habilis species, and there’s no doubt that it overlaps considerably with erectus”
- The fact that the two hominid species lived together in the same lake basin for so long and remained separate species, Meave Leakey said in a statement from Nairobi, “suggests that they had their own ecological niche, thus avoiding direct competition”
Cell walls of the kingdom plantae are made of cellulose
When a substance, like water, moves from an area of high concentration to low concentration.
In other words, the substance goes from where it is to where it isn’t.
Answer: a. An earlier start to spring.
Explanation: Notice that this is my opinion and might not be the correct answer! The growing season is the period of the year when crops and other plants grow successfully. And this season depends on warm temperatures, so if spring starts earlier, this adds warm time to the growing season.
