Evolution is gradual change of heritable traits (determined by an organism’s alleles) in a population across generations, eventually generating new species over time.. Organism DNA. 1a. Some of the strongest evidence for evolutionary relationships comes from studying the DNA of different organisms.. 1b. The fact that all organisms use the same DNA molecule to code for genetic information suggests that these organisms share a distant ancestor.. A mechanism for change in populations.. Any change in the . inherited . traits within a population across generations. Individuals better adapted to their environment tend to survive and . produce more offspring. History of Evolution. The evolution of life is linked to the physical and chemical evolution of the earth.. Life on earth evolved in two phases over the past 4.7 -4.8 billion years. Chemical evolution (1 billion years) of the organic molecules and systems of chemical reactions needed to form the first proto-cells..

Problematic – species only looked similar on the outside, but inside were very different . Evolution. – when a species of plants or animals adapts to their environment in order to survive over a long period of time. Key points!. Species. Plants or Animals. Adaptations. In order to survive. Adaptation. Adaptations are inherited traits that increase a group’s chance of . survival & reproduction. This type of finch has a thick beak .  adaptation for cracking open seeds. Variation.
