PPT-Species and Populations

Significant ideas A species interacts with its abiotic and biotic environments and its niche is described by these interactions Populations change and respond to interactions with the environment.

Island in Lake Malawi in the 1960s, has split into two genetically distinct populations, located at the north and south ends of the island. How can scientists determine whether these populations are now different species, according to the biological species concept?. There is overwhelming evidence for the evolution of life on Earth. . Evolution in summary. Evolution occurs when heritable characteristics of a species change. . Evolution at its most fundamental level simply describes a . and Population Control. Chapter 5 (Miller and . Spoolman. , 2010). Figure 5.1. An endangered southern sea otter in Monterey Bay, California (USA), uses a stone to crack the shell of a clam (insert). It lives in a giant kelp bed near San Clemente Island, California (background). Scientific studies indicate that the otters act as a keystone species in a kelp forest system by helping to control the populations of sea urchins and other kelp-eating species..

Per the theory - You would expect older rock to contain mostly organisms that are less complex and less like current (living) organisms.

It is the variety of earth’s species, the genes they contain, the ecosystems in which they live, and the ecosystems processes such as energy flow and nutrient cycling that sustain all life..

Daniele Dendi. a- Do you expect evolutionary forces to act on the new iguana population of Anguilla? If yes, which evolutionary agent (s) do you expect to act on this population?. b- Outline a study designed to test your hypothesis that the evolutionary agent (s) you identified in the previous question produced allele frequency differences in the 2 populations of iguanas (the “old” population of Guadalupe and the “new” population of Anguilla)..
