Because new species will eventually evolve to replace those that humans are driving to extinction, why is declining biological diversity such a threat?

How does an understanding of evolution enhance our ability to conserve endangered species? Think back to all of the topics we discussed this semester and how they might apply to species conservation.

The Endangered Species Act (ESA) of 1973 has helped to slow the destruction of habitat and the loss of species in the United States.  There are now many success stories of animals/plants that were on the edge of extinction and now are returning.  Even with the success stories there are many who criticize ESA. I want you to give at least 2 examples (with explanation) that show the success and need for The Endangered Species Act. And give 2 reasons why ESA is still criticized after all these years.

Which part of these statements isn't right ?       A species is a group of organisms that can potentially interbreed with one another to produce viable, fertile offspring. Speciation is when two new species form from one original one. Sympatric speciation occurs when there is a geographic separation of a population. Allopatric speciation occurs while the population remains in the same area. Adaptive radiation occurs when one species evolves into many to fill several different niches. Natural selection requires traits to be passed from parent to offspring, more offspring are produced than can survive creating competition, and inherited traits vary among offspring. Fossils, Anatomy and embryology, biogeography, and molecular biology all provide support for the theory of evolution. Evolution can be driven by many different things. Mutations are changes in DNA that create new alleles in a population. Gene flow is the flow of alleles in and out of a population resulting from the migration…

Are all species introductions the fault of humans?

Insects are the largest group of animals on Earth. Insect diversity is greatest in the tropics, where habitat destruction and species extinction are occurring at an alarming rate. What biological, economic, and ethical arguments can you advance to persuade people and governments to preserve this biological diversity? Instructions:

Define extinction

How does natural selection help species adapt to the pressures of their biome?
