The concept of uniformitarianism, articulated by James Hutton in the late 1700s, states that O the genetic code is similar among all living and extinct species mutations accumulate at a constant rate in most organisms current geological processes on Earth operate in the same manner as those that operated in the past the rate of extinction has been constant throughout the time life has existed on Earth

EVOLUTION CONNECTION The fossil record indicates that therehave been five mass extinction events in the past 500 millionyears (see Concept 25.4). Many ecologists think we are on theverge of entering a sixth mass extinction event. Briefly discussthe history of mass extinctions and the length of time it typicallytakes for species diversity to recover through the process ofevolution. Explain why this should motivate us to slow theloss of biodiversity today.
Many fossils existed in one layer of rock, but not in others from different time periods and this fossil record separated by rock layers was a map showing that life has changed over time.

Recent reconstructions of evolutionary history are often dependenton assigning divergence in terms of changes in amino acid ornucleotide sequences. For example, a comparison of cytochromec shows 10 amino acid differences between humans and dogs,24 differences between humans and moths, and 38 differencesbetween humans and yeast. Such data provide no information asto the absolute times of divergence for humans, dogs, moths, andyeast. How might one calibrate the molecular clock to an absolutetime clock? What problems might one encounter in such acalibration?
Why is the study of biogeography an important tool in explaining how species have evolved? * It shows us the relationship between a species' environment, and how they have evolved It shows us how the DNA has changed from one generation to the next It shows us how the bone structure of organisms has changed over time It shows us how old the Earth is Sign out US Lenovo ce %23 24 4. 5 7 08 9. backspace %D tab e y a d f g. k C V. alt alt ctrl

Due to conservation efforts, their population size today is above 30,000. How would the genetic diversity of the northern elephant seal population compare to the genetic diversity of the southern elephant seal population, which was not heavily hunted? * g Online sela on Periods 1 and 2 riods MP1, Highschool The northern elephant seal would have much less genetic varlation than the southern elephent seal. hool MP3, The southern elephant sea would have much less genetic variation than the northern elephant seal.
