<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”
Innate behavior is a behavior manifested that has not been taught nor learned. It is based on their basic instinct.
examples of innate behaviors are:
1) The spider weaving its web. It is not taught nor learned from experience. It has been inculcated in its mind since birth. The spider instinctively knew that to have its food, it must build a web where the food will be trapped.
2) The dog drooling when it is faced with food. It is an instinctive response when it sees food, one it particularly loves.

C. Wind erosion is caused by the wind blowing loose particles of dirt and/or sand from bare and flat lands. Plant structure above ground (leaves and stem) act to shield the wind and plant roots act as anchors to hold down the soil to reduce the effects of wind erosion.
Answer:
The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere, terrestrial, and marine ecosystems. The conversion of nitrogen can be carried out through both biological and physical processes.
