Since the formation of the San Andreas Fault system 25-30 million years ago, the juxtaposition of the Pacific and North American plates has formed many faults in California that accommodate lateral motion between the plates.
hope this helps
Sorry I don’t know what it is. Hope you aren’t mad at me.
<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”
Answer:
Eukaryotes consist of membrane bound nucleus whereas prokaryotes lack a membranebound nucleus. Prokaryotic DNA is doublestranded and circular. ... The main difference between prokaryotic and eukaryotic DNA is that prokaryotic DNA is found in the cytoplasm whereas eukaryotic DNA is packed into the nucleus of the cell.
