Artificial selection- the identification by humans of desirable traits in plants and animals
Adaptation- the biological mechanism by which organisms adjust to new environments or to change their current environment
Fitness- reproductive success 
Natural selection- the process in nature by which organisms better adapted to their environment tend to survive 
Descent with modification- The idea that species change over time from a common ancestor
Principle of common descent- all the organism present on the Earth have evolved from a common ancestor and each species has diverged from a common ancestor in the past
Homologous structures- similar physical features in organisms that share a common ancestor 
Hox genes- play a key role in controlling the body plan
Charles Darwin- Proposed the theory of biological evolution by natural selection.

So basically it controls/acts on phenotypes and characteristics of organisms.]]> 2022-05-17 02:27:13 UTC https://padlet.com/2024jordank/plt4o7cynwyie83r/wish/2186764022 2024jordank https://padlet.com/2024jordank/plt4o7cynwyie83r/wish/2186770667 https://www.youtube.com/watch?v=0SCjhI86grU]]> 2022-05-17 02:31:56 UTC https://padlet.com/2024jordank/plt4o7cynwyie83r/wish/2186770667 2024jordank https://padlet.com/2024jordank/plt4o7cynwyie83r/wish/2186774615

What do hox genes control? Answer: They determine the general body plan, such as the number of body segments of an animal, the number and placement of appendages, and animal head-tail directionality.

What were Lamarck’s ideas about evolution? Answer: He thought that living things evolved in a continuously upward direction, from dead matter, through simple to more complex forms.

What does natural selection directly act on? Answer: An organism's characteristics/phenotype. 

What shape will a graph have if it represents a polygenic trait? Answer: A bell shaped curve.

His theory helped generate the many different beliefs that people have as to how humans have evolved and come to be on Earth. Without his theories, we wouldn't be as scientifically advanced or aware of how we got here. That is why it is very important that we keep studying and applying his theories and concepts. ]]> 2022-05-17 02:38:53 UTC https://padlet.com/2024jordank/plt4o7cynwyie83r/wish/2186779582 2024jordank https://padlet.com/2024jordank/plt4o7cynwyie83r/wish/2186783260 2022-05-17 02:41:44 UTC https://padlet.com/2024jordank/plt4o7cynwyie83r/wish/2186783260 2024jordank https://padlet.com/2024jordank/plt4o7cynwyie83r/wish/2186784085 2022-05-17 02:42:17 UTC https://padlet.com/2024jordank/plt4o7cynwyie83r/wish/2186784085 2024jordank https://padlet.com/2024jordank/plt4o7cynwyie83r/wish/2186784632 2022-05-17 02:42:42 UTC https://padlet.com/2024jordank/plt4o7cynwyie83r/wish/2186784632 2024jordank https://padlet.com/2024jordank/plt4o7cynwyie83r/wish/2186785046 2022-05-17 02:43:03 UTC https://padlet.com/2024jordank/plt4o7cynwyie83r/wish/2186785046 2024jordank https://padlet.com/2024jordank/plt4o7cynwyie83r/wish/2186788445 2022-05-17 02:45:35 UTC https://padlet.com/2024jordank/plt4o7cynwyie83r/wish/2186788445 2024jordank https://padlet.com/2024jordank/plt4o7cynwyie83r/wish/2186788881 2022-05-17 02:45:57 UTC https://padlet.com/2024jordank/plt4o7cynwyie83r/wish/2186788881 2024jordank https://padlet.com/2024jordank/plt4o7cynwyie83r/wish/2186790907 2022-05-17 02:47:29 UTC https://padlet.com/2024jordank/plt4o7cynwyie83r/wish/2186790907
