|
The belief that Species are formed spontaneously (from nothing)
|
Spontaneous Generation! |
|
Examples of the Struggle for Survival for Existence is due to
|
Competition for limited resources such as food, water, harsh environment, predation, floods, drought, competing for mates and nesting sites! |
|
Gamete Mutations (unknown to Darwin)
|
Genetic DNA changes in a woman's ova (eggs) or man's sperm GAMETES, that will be passed on to next generations!
|
|
Heterozygous for Sickle Cell (relationship to Malaria) |
This trait does not have the disease and is protected from malaria. It turns out that the odd shape of some of the blood cells in a person who is heterozygous prevents the parasite that causes malaria from attaching to their cells!
|
|
Organisms Reproduce in Excess – Overpopulation |
To insure some offspring survive....the Oyster (114 million eggs in a single spawning season), and the Leatherback sea turtle (595 eggs in a single nesting season) and an elephant (6 offspring in her fertile 60 years)!
|
|
Somatic Mutations (unknown to Darwin) |
Body Cell DNA mutations, changes, damage to our DNA from smoking exposure to toxins, in our body cells usually leading to cancer!
|
|
Common Ancestor theory proposed by Darwin |
That many organisms descended from a previously existing common ancestors!
|
|
Descent with Modification (Darwin Idea) |
Some species look more similar and some more different since they have changed over millions of years!
|
|
Example 1 of Natural Selection (Darwin Idea) |
If only tall necked giraffes survive to reproduce, then over time the population or group will become taller!
|
|
Similar Embryology |
Similar pigs, mice, cats and human embryos is one evidence of Darwin's evolution! |
|
Definition of Natural Selection (Darwin Idea) |
The process in nature that causes evolution and natural selection of a species by reproductive success, and because they are better adapted and tolerant of the environment at that time!
|
|
Cytology |
The study of cells, matching proteins, this was not known to Darwin in his time!
|
|
Darwin's Finches |
17 different beaks types of these birds as there was different food sources available to them!
|
|
Can random changes in DNA of our gametes ever lead to an improvement in offspring? |
Yes, this is the mechanism behind evolution, occurring, the species with the mutations that match the current environment survive and reproduce!
|
|
Homozygous Recessive for Sickle Cell |
Hemoglobin blood disease where 1 amino acid mutation replaced with another causing a debilitating disease! |
