The Beringia hypothesis has been accepted for many years, but newer DNA evidence from sagebrush, trees, woolly mammoths, bison, rabbits, and other species found in sediments of ancient lakes that once separated the retreating glaciers suggest that the most recent land bridge was actually 12,600 years ago and not 25,000 to 15,000 years ago. How would these new findings alter the explanation for evidence of humans in North America dating to before 12,600 years ago?

"Human induced extinctions are therefore undesirable" Explain this ?
We have looked at what the fossil record can tell us about the amazing History of Life on Earth. We've examined the evidence for an early origin for life in the sea, 3800 million years, and investigated how life invaded life about 500 million years. We've also discussed the subsequent boom in life that massively increased biodiversity but also noted how the History of Life is frequently punctuated by mass extinctions. Today we stand on the threshold of a new mass extinction event. The biodiversity that we take for granted and that sustains humans is threatened to a degree only rarely seen in 4500 million years of Earth History. NOW TO CONCLUDE, ANSWER THE QUESTION. 1. ARE WE ON THE BRINK OF A MASS EXTINCTION? WHAT WOULD BE THE CONSEQUENCES FOR SOCIETY OF LOSING HALF OF ALL SPECIES BY 2100? ARE THERE ACTIONS THAT WE CAN TAKE AS INDIVIDUALS AND AS SOCIETY TO HELP PROTECT LIFE ON EARTH?
According to Figure 2 above, how many extinction events contributed to the end-Ordovician mass extinction and when did they occur?
Would you anticipate the DNA sequences of people living in what is now known as Italy in 1000BC to be similar to those living in the same area in 1900BC? If so, why or why not?

Why are fossils from tropical rainforests (such as Brazilian Amazon) more rarely found than the ones from more temperate biomes (such as Canadian Rocks)?
How does finding the same fossils of a land animal on two different continents support the hypothesis of continental drift? A) The land animal fossil is now found in colder parts of the world which means the continents had drifted since the fossils were made. B) The land animal fossil could only have ended up fossilized on both continents if they were once together C) The land animal fossil was unable to swim across oceans so the fact that its fossils were found on distant continents suggested those continents had once been fused together as later moved apart. D) The land animal fossil wasnt found in Asia which wegner thought was only stable continent that hadn’t moved.

Imagine that you have the DNA sequences fromthe intron of a gene in three species called A, B,and C. Species A and B are most closely related,while C is more distantly related. The sequencesof A and B differ by 18 base pairs, A and C differby 26 base pairs, and B and C differ by 28 basepairs. Fossils show that species A and B divergedabout 1.2 Mya, but there is no fossil evidence asto when the most recent common ancestor ofall three species lived. Use the genetic data toestimate that date. What assumptions are youmaking to get this estimate?
