Question

Based on modern evolutionary theory, which of the statements below explains why this species is able to camouflage itself.
(1 point)
• It may have changed because the lizard ate the bark of the tree
• It may have changed its color because it saw a bug changing its color.
• It may have changed due to an instant gene mutation
• It may have changed its color to avoid a predator
Below are structures that belong to 4 species with a common ancestor. These are examples of:
Carpals
Metacarpals
Phalanges
Human
Whale
(1 point)
• Crossing over
• Analogous structures
•samananus strictires

Answer 1

1) It may have changed its color to avoid a predator.
- Modern evolution (natural selection) explains camouflage as a trait that becomes common because individuals with better camouflage survive predators and leave more offspring.

2) These are examples of homologous structures.
- Carpals, metacarpals and phalanges in humans and whales are structurally similar because they were inherited from a common ancestor (not analogous structures).
