Reduction in population size, inbreeding, loss of variation are just the first steps in this process.
What is extinction vortex

Farming evolved in this region.
What is the Fertile Crescent?

Some of our characteristics are hardwired in our genes, while others are shaped by both genes and this biological process, which begins at fertilization.
What is development?
200
Mitochondria and chloroplasts evolved by this process.
What is endosymbiosis?
200
This is the least probable model of how two populations evolve reproductive barriers.
What is sympatric speciation?
200
We might consider this alternative to rewilding a slightly ironic approach to conservation.
What is trophy hunting
200
Picking fruit and thermoregulation are just two advantages of this innovation.
What is bipedalism
300
Darwin speculated that this type of inheritance was at work in nature, although he recognized that it might be wrong. Afterall, it contradicted the observation that life is tremendously diverse.
What is blending inheritance?
300
Most extant phyla and body plans evolved during this event and time before present.
What is the Cambrian Explosion and 543 million years ago?
300
Is natural selection really the only process responsible for the evolution of complex adaptations, or might this process also play a significant role?
What is emergence
300
This process can become a dominant evolutionary force after a bottlenecking event.
What is genetic drift
300
There is very little this among humans due to the recency of our species.
What is genetic variation
400
When two doubly heterozygous parents are mated, this is the expected ratio of phenotypes in the offspring population.
What is 9:3:3:1.
400
Transitional forms are hard to find, but this is one of the most convincing fossils linking reptiles and birds.
What is Archaeopteryx
400
Evolution will occur unless all assumptions of this theorem are obeyed by a population.
What is HWE
400
The elimination of this continues to be the main driver of extinction.
What is habitat?

This feature of non-human ape skulls increases the strength of the jaw.
What is saggital crest

I live with my spouse. We have a dog and one goldfish. According to the Simpson’s Diversity Index, this is the level of species diversity in my house.
What is 1-0.375 = 0.625?

This radioactive element is suitable for dating some of the earliest fossils on earth.
What is Uranium238

“Biological systems evolve” is the only proposition we learned about that is true without empirical evidence of evolution in nature; it can simply be deduced from logic and what we know about two properties of biological systems, namely reproduction and this.
What is heritable variation
500
Cheetahs once roamed North America, which explains the running speed of this wild animal.
What is American pronghorn?

This is the currently accepted cellular-level explanation of empathy among apes, especially humans.
