Study Notes

Camouflage and Structural Adaptations

Camouflage aids in survival by allowing organisms to blend into their environment, making it difficult for predators or prey to spot them.

Insulation and Functional Adaptations

Insulation functions by providing a layer that retains body heat, helping animals maintain a stable internal temperature in cold environments.

Sweating and Functional Adaptations

Sweating is a cooling mechanism where moisture evaporates from the skin, helping regulate body temperature during heat.

Smaller Animals in Hot Climates

Smaller animals have a higher surface area to volume ratio, enabling quicker heat dissipation, making them better suited for very hot climates.

Hibernation and Functional Adaptations

Hibernation conserves energy during periods of food scarcity and harsh conditions, slowing metabolism and reducing the need for resources.

Behavioral Adaptations for Survival

Behavioral adaptations, such as migration or nocturnal activity, enhance survival by helping animals find food, avoid predators, or adapt to environmental changes.

Predator Avoidance Behaviors

Example behaviors include hiding, exhibiting warning colors, and mimicking other species to avoid detection by predators.

Variations Within Species

Variation is influenced by genetic differences, environmental factors, and mutations, contributing to the diversity seen within species.

Environmental Selection Process

Natural selection is the process by which the environment favors certain traits, reducing the occurrence of less favorable characteristics over generations.

Speciation

Speciation is the process through which new species arise from existing ones, often due to reproductive isolation or environmental changes.

Divergent Evolution

Divergent evolution occurs when two or more related species develop different traits and adapt to various environments over time.

Homologous Characteristics

Homologous characteristics are anatomical features that share a common ancestry but may serve different functions in modern species.

Evidence Supporting Evolution

Fossil records, comparative anatomy, and molecular biology provide extensive evidence to support the theory of evolution.

Origin of Life on Earth

Life began on Earth approximately 3.5 billion years ago, as indicated by the oldest fossil records.

Analogous Structures

Analogous structures refer to features in different species that serve similar functions but evolved independently, often due to similar environmental pressures.

Biochemistry as Evidence for Evolution

Biochemical evidence includes DNA and protein comparisons that show evolutionary relationships and shared ancestry among species.

Adaptive Radiation Results

Adaptive radiation occurs when a single ancestral species rapidly evolves into a diverse range of forms to occupy different ecological niches.

Survival of the Fittest

"Survival of the fittest" refers to the concept that individuals with advantageous traits are more likely to survive, reproduce, and pass on those traits to future generations.
