Summary Introduction

To suggest: An evolutionary hypothesis to explain why mammals and birds living at the higher altitudes are, on average larger and bulkier than related species living at lower latitudes.

Concept introduction: Thermoregulation is a homeostatic mechanism by which organisms maintain a constant body temperature regardless of external fluctuations. The inability to do so can result in death of an organism.

How would you apply this in a Lamarckian explanation? Tiger Moths (Bertholdia trigona) produce high pitched ultrasonic clicking (at a rate of 4500 clicks/sec) when they hear the echolocation calls of bats (bats eat moths). As a result, the bat's sonar is jammed and the Tiger Moth escapes without being caught, killed, and eaten. Please use your knowledge of Evolution by Natural Selection to explain the process by which this remarkable anti-predator defense evolved in Tiger Moths. Please use your Knowledge of Evolution by Natural Selection to explain the process by which this remarkable anti-predator defense evolved in Tiger Moths.
What makes the ecosystem of the Galapagos Island different than those found on large continentals?  Upon what did Charles Darwin's original research on finches of the Galapagos Island focus?  Describe the research Peter and Rosemary Grant conducted on the finches in the 1970's.  Discuss the relationship between the finches' beak depth size and survival in terms of natural selection and fitness and the environmental causes that shaped the finch population of the islands.
Imagine that you are an evolutionary biologist currenyly studying a particular species of snake on an island off the coast of Durban, South Africa and that you have information indicating that1000 years ago, the same species of snakes in that island was observed to exist in a variety of colours (Red blue,yellow green) and that most of the snakes were blue. This same species of snakes and the same mixof colours were also found on the mainland (i.e Kwazulu Natal)  Assuming that all the snakes are descended from an ancestral blue snake, explain this change in colour frequency (evolution) as though it were based solely on each of the following processes.  a. Natural selection  b. Bottleneck effect  c. Founder effect
